When complications arise during labor and birth, risk of perinatal morbidity and mortality increases. Some complications are anticipated, especially if the mother is identified as high risk during the antepartum period; others are  unexpected or unforeseen. The woman, her family, and the obstetric team can feel devastated when things go wrong. Nurses must recognize these feelings if they are to provide effective support. It is crucial for nurses to understand the normal birth process to prevent and detect deviations from normal labor and birth and to implement nursing measures when complications arise. Optimal care of the laboring woman, fetus, and family experiencing complications is possible only when the nurse and other members of the obstetric team use their knowledge and skills in a concerted effort to provide care. This chapter focuses on the problems of preterm labor and birth, dystocia, and postterm pregnancy and obstetric emergencies.



Dystocia is long, difficult, or abnormal labor; it is caused by various conditions associated with the five factors affecting labor. It is estimated that dystocia occurs in approximately 8% to 11% of women during the first stage of labor when the fetus is in a vertex presentation. Secondstage dystocia is equally as common (Wiznitzer, 1995).

Dystocia can be caused by any of the following:

• Dysfunctional labor, resulting in ineffective uterine contractions or maternal bearing-down efforts (the powers); the most common cause of dystocia (Cunningham et al., 2001)

• Alterations in the pelvic structure (the passage)

• Fetal causes, including abnormal presentation or position, anomalies, excessive size, and number of fetuses (the passenger)

• Maternal position during labor and birth

• Psychologic responses of the mother to labor related to past experiences, preparation, culture and heritage, and support system

These factors are interdependent. In assessing the woman for an abnormal labor pattern, the nurse must consider the way in which these factors interact and influence labor progress. Dystocia is suspected when there is an alteration in the characteristics of uterine contractions, a lack of progress in the rate of cervical dilation, or a lack of progress in fetal descent and expulsion.



Dysfunctional labor is described as abnormal uterine contractions that prevent the normal progress of cervical dilation, effacement (primary powers), or descent (secondary powers). Dysfunction of uterine contractions can be further described as being hypertonic or hypotonic.

Several factors seem to increase a woman's risk for uterine dystocia, including the following:

• Body build (e.g., 30 pounds or more overweight, short stature)

• Uterine abnormalities (e.g., congenital malformations, overdistention as with multiple gestation or hydramnios)

• Malpresentations and positions of the fetus

• Cephalopelvic disproportion

• Overstimulation with oxytocin

• Maternal fatigue, dehydration and electrolyte imbalance, and fear

• Inappropriate timing of analgesic or anesthetic administration

Research has also documented a familial occurrence of dystocia. Laboring women whose mothers or sisters experienced dystocia during their labors had an increased risk for experiencing dystocia themselves, possibly related to a genetic factor affecting uterine activity (Berg-Lekas, Hogberg, & Winkvist, 1998).


Hypertonic uterine dysfunction

The woman experiencing hypertonic uterine dysfunction, or primary dysfunctional labor, often is an anxious first-time mother who is having painful and frequent contractions that are ineffective in causing cervical dilation or effacement to progress. These contractions usually occur in the latent stage (cervical dilation of less than 4 cm) and are usually uncoordinated (Fig. 4). The force of the contractions may be in the midsection of the uterus rather than in the fundus, and the uterus is therefore unable to apply downward pressure to push the presenting part against the cervix. The uterus may not relax completely between contractions (Gilbert & Harmon, 1998; Varney, 1997).


Fig. 4 Uterine contractility patterns in labor. A, Typical normal labor. B, Subnormal intensity, with frequency greater than needed for optimum performance. C, Normal contractions but too infrequent for efficient labor. D, Incoordinate activity. E, Hypercontractility.


Women experiencing hypertonic uterine dysfunction may be exhausted and express concern about loss of control because of the intense pain they are experiencing and the lack of progress. Therapeutic rest, which is achieved with a warm bath or shower and the administration of analgesics such as morphine, meperidine (Demerol), or nalbuphine (Nubain) to inhibit uterine contractions, reduce pain, and encourage sleep, is usually prescribed for the management of hypertonic uterine dysfunction. After a 4- to 6-hour rest these women are likely to awaken in active labor with a normal uterine contraction pattern (Gilbert & Harmon, 1998).


Hypotonic uterine dysfunction

The second and more common type of uterine dysfunction is hypotonic uterine dysfunction, or secondary uterine inertia. The woman, who may be in her first or a subsequent pregnancy, initially makes normal progress into the active stage of labor; then the contractions become weak and inefficient or stop altogether (see Fig. 4). The uterus is easily indented, even at the peak of contractions. Intrauterine pressure during the contraction (usually less than 25 mm Hg) is insufficient for progress of cervical effacement and dilation (Gilbert & Harmon, 1998). Cephalopelvic disproportion and malpositions are common causes of this type of uterine dysfunction.

A woman experiencing hypotonic uterine dysfunction may become exhausted and be at increased risk for infection. Management usually consists of performing an ultrasound examination to rule out cephalopelvic disproportion and assessing the fetal heart rate and pattern, characteristics of amniotic fluid if membranes are ruptured, and  maternal well-being. If findings are normal, measures such as ambulation, hydrotherapy, an enema, stripping or rupture of membranes, nipple stimulation, and oxytocin infusion can be used to augment the progress of labor (Varney, 1997).


Secondary powers

Secondary powers, or bearing-down efforts, are compromised when large amounts of analgesic are given. Anesthesia may also block the bearing-down reflex and, as a result, alter the effectiveness of voluntary efforts (Mayberry et al., 1999). Exhaustion resulting from lack of sleep or long labor and fatigue resulting from inadequate hydration and food intake affect the woman's voluntary efforts. Maternal position can work against the forces of gravity and decrease the strength and efficiency of the contractions. Table 2 summarizes the characteristics of dysfunctional labor.

Alterations in pelvic structure

Pelvic dystocia. Pelvic dystocia can occur whenever there are contractures of the pelvic diameters that reduce the capacity of the bony pelvis, including the inlet, midpelvis, outlet, or any combination of these planes.

Disproportion of the pelvis is the least common cause of dystocia (Cunningham et al., 2001). Pelvic contractures may be caused by congenital abnormalities, maternal malnutrition, neoplasms, or lower spinal disorders. An immature pelvic size predisposes some adolescent mothers to pelvic dystocia. Pelvic deformities may also be the result of automobile or other accidents.

An inlet contracture is diagnosed whenever the diagonal conjugate is less than 11.5 cm. The incidence of face and shoulder presentation is increased. Because these presentations interfere with engagement and fetal descent, the risk of prolapse of the umbilical cord is increased. Inlet contracture is associated with maternal rickets and a flat pelvis. Weak uterine contractions may be noted during the first stage of labor in affected women.

Midplane contracture, the most common cause of pelvic dystocia, is diagnosed whenever the sum of the interischial spinous and posterior sagittal diameters of the midpelvis is 13.5 cm or less. Fetal descent is arrested (transverse arrest of the fetal head) in such births because the head cannot rotate internally. These infants are usually born by cesarean, but vacuum-assisted birth has been used safely when the cervix is fully dilated. Midforceps-assisted birth usually is not done because of the increased perinatal morbidity associated with this intervention.

Outlet contracture exists when the interischial diameter is 8 cm or less. It rarely occurs in the absence of midplane contracture. Women with outlet contracture have a long, narrow pubic arch and an android pelvis, and this causes fetal descent to be arrested. Maternal complications include extensive perineal lacerations during vaginal birth because the fetal head is pushed posteriorly.

Soft tissue dystocia. Soft tissue dystocia results from obstruction of the birth passage by an anatomic abnormality other than that involving the bony pelvis. The obstruction may result from placenta previa (low-lying placenta) that partially or completely obstructs the internal os of the cervix. Other causes, such as leiomyomas (uterine fibroids) in the lower uterine segment, ovarian tumors, and a full bladder or rectum, may prevent the fetus from entering the pelvis. Occasionally, cervical edema occurs during labor when the cervix is caught between the presenting part and the symphysis pubis or when the woman begins bearing-down efforts prematurely, thereby inhibiting complete dilation. Sexually transmitted infections (e.g., human papillomavirus) can alter cervical tissue integrity and thus interfere with adequate effacement and dilation. Bandl's ring, a pathologic retraction ring, is associated with prolonged rupture of membranes and protracted labor (Cunningham et al., 2001).


Fetal causes

Dystocia of fetal origin may be caused by anomalies, excessive fetal size and malpresentation, malposition, or multifetal pregnancy. Complications associated with dystocia of fetal origin include neonatal asphyxia, fetal injuries or fractures, and maternal vaginal lacerations. Although spontaneous vaginal birth is possible in these instances, a low-forceps-assisted, vacuum-assisted, or cesarean birth often is necessary.

Anomalies. Gross ascites, large tumors, and open neural tube defects (e.g., myelomeningocele, hydrocephalus) are fetal anomalies that can cause dystocia. The anomalies affect the relationship of the fetal anatomy to the maternal pelvic capacity, with the result that the fetus is unable to descend through the birth canal.

Cephalopelvic disproportion. Cephalopelvic disproportion (CPD), also called fetopelvic disproportion, is related to excessive fetal size (i.e., 4000 g or more). It occurred at a rate of 18.3 per 1000 live births in 1999 (Ventura et al., 2001).

When CPD is present, the fetus cannot fit through the maternal pelvis to be born vaginally. Excessive fetal size, or macrosomia, is associated with maternal diabetes mellitus, obesity, multiparity, or the large size of one or both parents. If the maternal pelvis is too small, abnormally shaped, or deformed, CPD may be of maternal origin. In this case the fetus may be of average size or even smaller.

Malposition. The most common fetal malposition is persistent occipitoposterior position (i.e., right occipitoposterior or left occipitoposterior), occurring in approximately 25% of all labors. Labor, especially the second stage, is prolonged; the woman typically complains of severe back pain from the pressure of the fetal head (occiput) pressing against her sacrum. Box 24-9 identifles suggested measures to relieve back pain and facilitate rotation of the fetal occiput to an anterior position, which will facilitate birth (Gilbert & Harmon, 1998; Simkin, 1995).


BOX 9 Back LaborOcciput Posterior Position


Measures to Reduce Back Pain during a Contraction

Counterpressure: apply fist or heel of hand to sacral area

Heat or cold applications: apply to sacral area

Double hip squeeze:

Woman assumes a position with hip joints flexed such as knee-chest

Partner, nurse, or doula places hands over gluteal muscles and presses with palms of hands up and inward toward the center of the pelvis

Knee press:

Woman assumes a sitting position with knees a few inches apart and feet flat on the floor or on a stool

Partner, nurse, or doula cups a knee in each hand with heels of hands on top of tibia then presses the knees straight back toward the woman's hips while leaning forward toward the woman

Measures to Facilitate the Rotation of the Fetal Head (May Also Relieve Back Pain)

Lateral abdominal stroking: stroke the abdomen in direction that the fetal head should rotate

Hands-and-knees position (all-fours): can also be accomplished by kneeling while leaning forward over a birth ball, padded chair seat, bed, or over-the-bed table


Pelvic rocking

Stair climbing

Lateral position: lie on side toward which the fetus should turn

Lunges: widens pelvis on side toward which woman lunges

Woman stands, facing forward, next to/alongside a chair so that she can lunge toward the side the fetal back is on or in the direction of the fetal occiput

Places foot on seat of chair with toes pointed toward the back of the chair then lunges

Alternative position for lunge: kneeling


Malpresentation. Breech presentation is the most common form of malpresentation, occurring in 3% to 4% of all births and as many as 25°/o of preterm births. There are four main types of breech presentation: frank breech (thighs flexed, knees extended); complete breech (thighs and knees flexed); and two types of incomplete breech, one in which the knee extends below the buttocks and the other in which the foot extends below the buttocks (Fig. 5). Breech presentations are associated with multifetal gestation, preterm birth, fetal and maternal anomalies, hydramnios, and oligohydramnios. Diagnosis is made by abdominal palpation and vaginal examination and usually is confirmed by ultrasound scan (Laros, Flanagan, & Kilpatrick, 1995; Ventura et al, 2001).


Fig. 24-5 Types of breech presentation. A, Frank breech: thighs are flexed on hips; knees are extended. B, Complete breech: thighs and knees are flexed. C, Incomplete breech: foot extends below the buttocks. D, Incomplete breech: knee extends below the buttocks.


During labor, the descent of the fetus in a breech presentation may be slow because the breech is not as good a dilating wedge as the fetal head; the labor itself usually is not prolonged. There is risk of prolapse of the cord if the membranes rupture in early labor. The presence of meconium in amniotic fluid is not necessarily a sign of fetal distress because it results from pressure on the fetal abdominal wall as it traverses the birth canal. Assessment of fetal heart rate (FHR) and pattern should be used to determine whether the passage of meconium is an expected finding associated with breech presentation or is a nonreassuring sign associated with fetal hypoxia. The fetal heart tones of infants in a breech position are best heard at or above the umbilicus.

Vaginal birth is accomplished by mechanisms of labor that manipulate the buttocks and lower extremities as they emerge from the birth canal (Varney, 1997) (Fig. 6). Piper forceps sometimes are used to deliver the head. External cephalic version (ECV) may be tried to turn the fetus to a vertex presentation.

E, Internal rotation of shoulders and head. F, Face rotates to sacrum when occiput is anterior. G, Head is born by gradual flexion during elevation of fetal body.


Although opinions vary, a cesarean birth is commonly performed when the fetus is estimated to be larger than 3800 g or smaller than 1500 g, if this is a first pregnancy, if labor is ineffective, or if complications occur (Scott, 1999). Although cesarean birth reduces the risks to the fetus, the maternal risks are increased. ECV also poses risks and is not always successful. Women whose breech presentation occurs late in pregnancy need to be informed of the options for birth, as well as the risks associated with each option.

Face and brow presentations are uncommon and are associated with fetal anomalies, pelvic contractures, and CPD. Vaginal birth is possible if the fetus flexes to a vertex presentation, although forceps often are used. Cesarean birth is indicated if the presentation persists, if there is fetal distress, or if labor stops progressing.

Cesarean birth is usually necessary for a fetus in a shoulder presentation (i.e., the fetus is in a transverse lie), although ECV may be attempted after 38 weeks of gestation (Cunningham et al., 2001; Varney, 1997).

Multifetal pregnancy. Multifetal pregnancy is the gestation of twins, triplets, quadruplets, or more infants. Since 1980, the twin birthrate has increased by 53%. The twin birthrate was 28.9 per 1000 live births in 1999. The higher-order multiple birthrate (i.e., triplet and more) was 184.9 per 100,000 live births in 1999, representing the first decline in what had been a rapid escalation since 1980 (Ventura et al., 2001). It is likely that the rapid escalation was related to use of fertility-enhancing medications and procedures and the older age of childbearing. Refinements in the treatments used to treat infertility may be responsible for the recent decline in higher-order multiple births.

Multiple births are associated with more maternal complications (e.g., dysfunctional labor, hemorrhage) than are single births. The higher incidence of maternal complications and higher risk of perinatal mortality primarily stems from the birth of low-birth-weight infants resulting from preterm birth or IUGR in part related to placental dysfunction and twin-to-twin transfusion. Fetuses may experience distress and asphyxia during the birth process as a result of cord prolapse and the onset of placental separation with the birth of the first fetus.

In addition, fetal complications such as congenital anomalies and abnormal presentations can result in dystocia and an increased incidence of cesarean birth. For example, in only half of all twin pregnancies do both fetuses present in the vertex position, the most favorable for vaginal birth; in one third of the pregnancies, one twin may present in the vertex position and one in the breech (Cunningham et al., 2001; Ellings, Newman, & Bowers, 1998).

The health status of the mother may be compromised by an increased risk for hypertension, anemia, and hemorrhage associated with uterine atony, abruptio placentae, and multiple or adherent placentas. Duration of the phases and stages of labor may vary from the duration experienced with singleton births.

Teamwork and planning are essential components of the management of childbirth in multiple pregnancies. Early detection and care of complications associated with multiple births is essential to achieve a positive outcome for mother and babies. Maternal positioning and active support are used to enhance labor progress and placental perfusion. Emotional support that includes expression of feelings and full explanations of events as they occur and of the status of the mother and the fetuses/newborns is important to reduce the anxiety and stress the mother and her family experience (Ellings, Newman, & Bowers, 1998).


Position of the woman

The functional relationships between the uterine contractions, the fetus, and the mother's pelvis are altered by the maternal position. In addition, the position can provide either a mechanical advantage or disadvantage to the mechanisms of labor by altering the effects of gravity and the body part relationships important to the progress of labor. For example, the hands-and-knees position facilitates rotation from a posterior occiput position more effectively than does the lateral position. Sitting and squatting facilitate fetal descent during pushing and shorten the second stage of labor (Biancuzzo, 1993). Discouraging maternal movement or restricting labor to the recumbent or lithotomy position may compromise progress. The incidence of dystocia in women confined to these positions is increased, resulting in increased need for augmentation of labor or the use of forceps-assisted, vacuum-assisted, or cesarean birth.


Psychologic responses

Hormones released in response to stress can cause dystocia. Sources of stress vary for each woman, but pain and the absence of a support person are two recognized factors. Confinement to bed and restriction of maternal movement can be a source of psychologic stress that compounds the physiologic stress caused by immobility in the nonmedicated laboring woman. When anxiety is excessive, it can inhibit cervical dilation and result in prolonged labor and increased pain perception. Anxiety also causes increased levels of stress-related hormones (e.g., betaendorphin, adrenocorticotropic hormone, cortisol, epinephrine). These hormones act on the smooth muscles of the uterus; increased levels can cause dystocia by reducing uterine contractility (Biancuzzo, 1993).


Abnormal labor patterns

In 1999 prolonged labor patterns occurred at a rate of 7.9 per 1000 live births. The incidence of prolonged labor patterns was slightly higher (i.e., 8.4) among women who were under 20 years of age (Ventura et al., 2001).

Six abnormal labor patterns have been identified and classified by Friedman (1989) according to the nature of the cervical dilation and fetal descent. The labor patterns seen in normal and abnormal labor are described in Table 3.


TABLE 3 Labor Patterns in Normal and Abnormal Labor


1. Dilation: continues

a. Latent phase: <4 cm and low slope

b. Active phase: >5 cm or high slope

c. Deceleration phase >9 cm

2. Descent: active at >9 cm dilation





Prolonged latent phase

>20 hr

>14 hr

Protracted active phase dilation

<1.2 cm/hr

<1.5 cm/hr

Secondary arrest: no change



Protracted descent

<1 cm/hr

<2 cm/hr

Arrest of descent

>1 hr

>V2 hr

Failure of descent

No change during deceleration phase and second stage

Precipitous labor

>5 cm/hr

10 cm/hr


These patterns may result from a variety of causes, including ineffective uterine contractions, pelvic contractures, CPD, abnormal fetal presentations or position, early use of analgesics, conduction anesthesia, and anxiety and stress. Progress in either the first or second stage of labor can be protracted (prolonged) or arrested (stopped). Abnormal progress can be identified by plotting cervical dilation and fetal descent on a labor graph (partogram) at various intervals after the onset of labor and comparing the resulting curve with the expected labor curve for a nulliparous or multiparous labor.

Health care providers must be careful when diagnosing a labor pattern as prolonged and when intervening based on this diagnosis. Criteria defining the differences between false, latent, and active labor should be established. Using hospital admission areas to evaluate a woman's labor status is helpful in preventing the premature implementation of labor interventions such as induction of epidural anesthesia. If a woman is found to be in false or latent (early) labor she can be sent home or remain in the admissions area until labor becomes active (McNiven et al., 1998).

Maternal morbidity and death may occur as a result of uterine rupture, infection, serious dehydration, and postpartum hemorrhage, all possible consequences of abnormal labor patterns. The fetus is at increased risk for hypoxia. A long and difficult labor also can have an adverse psychologic effect on the mother, father, and family.

Precipitous labor. Precipitous labor occurred at a rate of 19.9 per 1000 live births in 1999. Precipitous labor occurred at a slightly higher rate among women ages 35 to 54 and at the lowest rate (i.e., 14.3) among women younger than 20 years of age (Ventura et al., 2001).

Precipitous labor may result from hypertonic uterine contractions that are tetanic in intensity. Maternal and fetal complications can occur as a result. Maternal complications include uterine rupture, lacerations of the birth canal, amniotic fluid embolism, and postpartum hemorrhage. Fetal complications include hypoxia caused by decreased periods of uterine relaxation between contractions and intracranial hemorrhage related to rapid birth (Cunningham et al., 2001).

Women who have experienced precipitous labor often describe feelings of disbelief that their labor began so quickly, alarm that their labor progressed so rapidly, panic about the possibility they would not make it to the hospital on time to give birth, and finally relief when they arrived at the hospital. In addition, women have expressed frustration when nurses would not believe them when they reported their readiness to push. Some women have difficulty remembering the details of their labor and birth and require others, including caregivers, to help them fill in the gaps in their memory (Rippin-Sisler, 1996).


Assessment and Nursing Diagnoses

Risk assessment is a continuous process in the laboring woman. Review of the findings obtained during the initial interview conducted at the woman's admission to the labor unit and ongoing observations of her psychologic response to labor may reveal factors that can be a source of dysfunctional labor. These factors may include anxiety or fear, a complication of pregnancy, or previous labor complications. The initial physical assessment and ongoing assessments provide information about maternal well-being; status of labor in terms of the characteristics of uterine contractions and progress of cervical effacement and dilation; fetal well-being in terms of FHR and pattern, presentation, station, and position; and status of the amniotic membranes. Ultrasound scanning can identify potential dysfunctional labor problems related to the fetus or maternal pelvis. All these assessments contribute to accurate identification of potential and actual nursing diagnoses related to dystocia and maternal-fetal compromise.

Nursing diagnoses that might be identified in women experiencing dystocia include the following:

• Risk for maternal or fetal injury related to

-interventions implemented for dystocia

• Powerlessness related to

-loss of control

• Risk for infection related to

-rupture of membranes

• Ineffective coping related to

-lack of support system


Expected Outcomes of Care

Expected outcomes for the woman who is experiencing dystocia include that the woman will do the following:

• Understand the causes and treatment of dysfunctional labor

• Use measures recommended by the obstetric care team to enhance the progress of labor and birth

• Express relief of pain

• Experience labor and birth with minimal or no complications, such as infection, injury, or hemorrhage

• Give birth to a healthy infant who has not experienced fetal distress

Plan of Care and Interventions

Nurses assume many caregiving roles when labor is complicated. They also work collaboratively with other health care providers in providing care. Interventions that the nurse may implement or assist with include external cephalic version, trial of labor, induction or augmentation with oxytocin, amniotomy, and operative procedures. The nursing role is identified with each of the procedures described.


LEGAL TIP Standard of Care—Labor and Birth Complications

• Document all assessment findings, interventions, and patient responses on patient record and monitor strips according to unit protocols, procedures, and policies and professional standards.

• Assess whether the woman (and her family, if appropriate) is fully informed about procedures for which she is consenting.

• Maintain safety in administering medications and treatments correctly.

• Have verbal orders signed as soon as possible.

• Provide care at the acceptable standard (e.g., according to hospital protocols and professional standards).

• If short staffing occurs in the unit and the nurse is assigned additional patients, the nurse should document that rejecting this additional assignment would have placed these patients in danger as a result of abandonment.

• Maternal and fetal monitoring continues until birth according to the policies, procedures, and protocols of the birthing facility, even when a decision to carry out cesarean birth is made.




Version is the turning of the fetus artificially from one presentation to another and may be done either externally or internally.

External cephalic version. External cephalic version (ECV) is used to attempt to turn the fetus from a breech or shoulder presentation to a vertex presentation for birth. It may be attempted in a labor and birth setting after 37 weeks of gestation. Before it is attempted, ultrasound scanning is done to determine the fetal position; locate the umbilical cord; rule out placenta previa; and assess the amount of amniotic fluid, the fetal age, and the presence of any anomalies. A nonstress test is performed to confirm fetal wellbeing, or the FHR pattern is monitored for a time (usually 10 to 20 minutes). Informed consent is obtained. Contraindications to ECV include uterine anomalies, previous cesarean birth, CPD, placenta previa, multifetal gestation, and oligohydramnios (Cunningham et al., 2001; Laros, Flanagan, & Kilpatrick, 1995).

ECV is accomplished by the exertion of gentle, constant pressure on the abdomen (Fig. 7). A tocolytic agent, such as magnesium sulfate or terbutaline, often is given to relax the uterus and facilitate the maneuver. Ultrasound scanning is done to identify potential problems, such as cord entanglement and placental separation (Cunningham et al., 2001; Laros, Flanagan, & Kilpatrick, 1995).

During an attempted ECV, the nurse continuously monitors the FHR, especially for bradycardia; checks the maternal vital signs; and assesses the woman's level of comfort because the procedure may cause discomfort. After the procedure is completed, the nurse continues to monitor maternal vital signs, uterine activity, and FHR and assess for vaginal bleeding until the woman's condition is stable. Women who are Rh negative should receive Rh immune globulin because the manipulation can cause fetomaternal bleeding (Cunningham et al., 2001; Laros, Flanagan, & Kilpatick, 1995).

Internal version. With internal version, the fetus is turned by the physician, who inserts a hand into the uterus and changes the presentation to cephalic (head) or podalic (foot). Internal version may be used in multifetal pregnancies to deliver the second fetus. The safety of this procedure has not been documented; maternal and fetal injury is possible. Cesarean birth is the usual method for managing malpresentation in multifetal pregnancies. The nurse's role is to monitor the status of the fetus and to provide support to the woman.


Trial of labor

A trial of labor (TOL) may be initiated if the mother's pelvis is of questionable size or shape, if the fetus is in an abnormal presentation, or if she wishes to have a vaginal birth after a previous cesarean birth. It is a form of care likely to be beneficial when implemented after a previous low segment cesarean birth (Enkin et al., 2001). Fetal sonography or maternal pelvimetry may be done before a TOL to rule out CPD. The cervix must be soft and dilatable. During TOL, the woman is evaluated for the occurrence of active labor, including adequate contractions, engagement and descent of the presenting part, and effacement and dilation of the cervix. Nurses must recognize that the woman and her partner are often anxious about her health and well-being and that of their baby. Supporting and encouraging the woman and her partner and providing information regarding progress can reduce stress, enhance the labor process, and facilitate a successful outcome.


Induction of labor

Induction of labor is the chemical or mechanical initiation of uterine contractions before their spontaneous onset for the purpose of bringing about the birth. In 1999 approximately 20% of women who gave birth had their labors induced, a doubling of the labor induction rate in 1990 (Ventura et al., 2001). Induction may be indicated for a variety of medical and obstetric reasons. These include pregnancy-induced hypertension, diabetes mellitus and other medical problems, postterm gestation, suspected fetal jeopardy (e.g., IUGR), logistic factors such as history of previous rapid birth or distance of the woman's home from the hospital, and fetal death. Under such conditions, the risk to the mother or fetus is less than the risk of continuing the pregnancy (Mathews, 1998).

Both chemical and mechanical methods are used to induce labor. Intravenous oxytocin and amniotomy are the most common methods used in the United States. Less commonly used methods include nipple stimulation (manual or with a breast pump), the ingestion of castor oil or herbal preparations, a soap-suds enema, stripping of the membranes, and acupuncture (Summers, 1997). Prostaglandins are also used for inducing labor, but their use for this purpose continues to be investigated (Mastrogiannis & Knuppel, 1995; Summers, 1997).

Success rates for induction of labor are higher when the condition of the cervix is favorable, or inducible. A rating system such as the Bishop score (Table 4) can be used to evaluate inducibility. For example, a score of 9 or more on this 13-point scale might indicate that the cervix is soft (2), anterior (2), 50% or more effaced (1), and dilated 2 cm or more (1) and that the presenting part is engaged (3). Induction of labor is likely to be more successful if the score is 9 or more (Cunningham et al., 2001).

Cervical ripening methods

Chemical agents. A prostaglandin E2 gel has been approved by the FDA since 1993 as a cervical ripening agent. Currently, preparations of prostaglandin Ej and prostaglandin E2 can used before induction to "ripen" (soften and thin) the cervix (see Medication Guides). This treatment usually results in a higher success rate for the induction of labor, the need for lower dosages of oxytocin during the induction, and shorter induction times. In some cases, women will go into labor after the administration of prostaglandin, thereby eliminating the need to administer oxytocin to induce labor (ACOG, 1995b; Gilbert & Harmon, 1998; Mundle & Young, 1996; Simpson & Poole, 1998; Summers, 1997; Wilson, 2000).


Medication Guide

Cervical Ripening Using Prostagiandin E, (PGE-,): Misoprostol CCytotec)


PGE, ripens the cervix, making it softer and causing it to begin to dilate and efface; stimulates uterine contractions.


PGE, is used for preinduction cervical ripening (ripen cervix before oxytocin induction of labor when the Bishop score is 4 or less) and to induce labor or abortion

(abortifacient agent).


Insert 25 to 50 jxg (1/4 to 1/2 of a 100-/u,g tablet) intravaginally into the posterior fornix using the tips of index and middle fingers without the use of a lubricant. Repeat every 4 to 6 hours as needed to a maximum of 300 to 400 ;u,g in a 24-hour period or until an effective contraction pattern is established (3 or more uterine contractions in 10 minutes), cervix ripens (Bishop score of 8 or greater), or significant adverse reactions occur.

Administer: 50-100 /xg, PO q4-6h (Gl effects increased; may be less effective)


Higher dosages are more likely to result in adverse reactions such as nausea and vomiting, diarrhea, fever, tachysystole (12 or more uterine contractions in 20 minutes without alteration of FHR pattern), hyperstimulation of the uterus (tachysystole with nonreassuring FHR patterns), or fetal passage of meconium.


• Explain procedure to woman and her family. Ensure that an informed consent has been obtained as per agency policy.

• Assess maternal-fetal unit, before each insertion and during treatment following agency protocol for frequency.

Assess maternal vital signs and health status, FHR pattern, and status of pregnancy, including indications for cervical ripening or induction of labor, signs of labor or impending labor, and the Bishop score. Recognize that a nonreassuring FHR pattern; maternal fever, infection, vaginal bleeding, or hypersensitivity; and regular, progressive uterine contractions contraindicate the use of misoprostol.

• Use caution if the woman has a history of asthma, glaucoma, or renal, hepatic, or cardiovascular disorders.

• Have woman void before procedure.

• Assist woman to maintain a supine position with lateral tilt or a side-lying position for 30 to 40 minutes after insertion.

• Prepare to swab vagina to remove unabsorbed medication using a saline soaked gauze wrapped around fingers and to administer terbutaline 0.25 mg subcutaneously or intravenously if significant adverse reactions occur.

• Initiate oxytocin for induction of labor 2 to 4 hours after last dose of misoprostol was administered, following agency protocol, if ripening has occurred and labor has not begun.

• Document all assessment findings and administration procedures.

Misoprostol (Cytotec) has not yet been approved by the FDA for cervical ripening or labor induction.

Medication Guide

Cervical Ripening Using Prostaglandin E2 (PGE2): Dinoprostone (Cervidil Insert; Prepidil Gel)


PGE2 ripens the cervix, making it softer and causing it to begin to dilate and efface; stimulates uterine contractions.


PGE2 is used for preinduction cervical ripening (ripen cervix before oxytocin induction of labor when the Bishop score is 4 or less), and to induce labor or abortion (abortifacient agent)


Place Cervidil insert (10 mg dinoprostone gradually released over 12 hours) intravaginally into the posterior fornix. Insert Prepidil gel (2.5-ml syringe containing 0.5 mg of dinoprostone) into cervical canal just below internal cervical os. Repeat gel insertion in 6 hours as needed to a maximum of 1.5 mg in a 24-hour period.

Continue treatment until maximum dosage is administered or until an effective contraction pattern is established (3 or more uterine contractions in 10 minutes), cervix ripens (Bishop score of 8 or greater), or significant adverse reactions occur.


Potential adverse reactions include headache, nausea and vomiting, diarrhea, fever, hypotension, tachysystole (12 or more uterine contractions in 20 minutes without alteration of FHR pattern), hyperstimulation of the uterus (tachy- systole with nonreassuring FHR patterns), or fetal passage of meconium.


• Explain procedure to woman and her family. Ensure that an informed consent has been obtained as per agency policy.

• Assess maternal-fetal unit, before each insertion and during treatment following agency protocol for frequency. Assess maternal vital signs and health status, FHR pattern, and status of pregnancy, including indications for cervical ripening or induction of labor, signs of labor or impending labor, and the Bishop score. Recognize that a nonreassuring FHR pattern; maternal fever, infection, vaginal bleeding, or hypersensitivity; and regular, progressive uterine contractions contraindicate the use of dinoprostone.

• Use caution if the woman has a history of asthma; glaucoma; or renal, hepatic, or cardiovascular disorders.

• Bring gel to room temperature before administration. Do not force warming process by using a warm water bath or other source of external heat (e.g., microwave).

• Have woman void before insertion.

• Assist woman to maintain a supine position with lateral tilt or a side-lying position for 30 to 60 minutes after insertion of gel or for 2 hours after placement of insert.

• Prepare to swab vagina to remove remaining gel using a saline-soaked gauze wrapped around fingers or pull string to remove insert and to administer terbutaline 0.25 mg subcutaneously or intravenously if significant adverse reactions occur.

• Initiate oxytocin for induction of labor within 6 to 12 hours after last instillation of gel or within 30 minutes after removal of the insert.

• Follow agency protocol for induction if ripening has occurred and labor has not begun.

• Document all assessment findings and administration procedures.

Dinoprostone is the only FDA-approved medication for cervical ripening or labor induction.


Mechanical methods. Hydroscopic dilators (substances that absorb fluid from surrounding tissues and then enlarge) also can be used for cervical ripening. Laminaria tents (natural cervical dilators made from seaweed) and synthetic dilators containing magnesium sulfate (Lamicel) are inserted into the endocervix without rupturing the membranes. As they absorb fluid, they expand and cause cervical dilation. These dilators are left in place for 6 to 12 hours before being removed to assess cervical dilation. Fresh dilators are inserted if further cervical dilation is necessary. Synthetic dilators swell faster than natural dilators and become larger with less discomfort (ACOG, 1995b; Simpson & Poole, 1998; Summers, 1997).

Hydroscopic dilators compare favorably with prostaglandins in terms of their effectiveness in ripening the cervix but are associated with a higher incidence of postpartum maternal and newborn infections. Nursing responsibilities for women who have dilators inserted include documenting the number of dilators and sponges inserted during the procedure, as well as the number removed, and assessment for urinary retention, rupture of membranes, uterine tenderness/pain, contractions, vaginal bleeding, and fetal distress (Gilbert & Harmon, 1998; Simpson & Poole, 1998).

Amniotomy. Amniotomy (artificial rupture of membranes) can be used to induce labor when the condition of the cervix is favorable (ripe) or to augment labor if progress begins to slow. Labor usually begins within 12 hours of the rupture; however, if amniotomy does not stimulate labor, the resulting prolonged rupture may lead to infection. Once an amniotomy is performed, the woman is committed to giving birth. For this reason, amniotomy often is used in combination with oxytocin induction. Before the procedure, the woman should be told what to expect; she should also be assured that the actual rapture of the membranes is painless for her and the fetus, although she may experience some discomfort when the Amnihook or other sharp instrument is inserted through the vagina and cervix (see Procedure box).


Procedur Assisting with Amniotomy


Explain to the woman what will be done.

Assess FHR before procedure begins to obtain a baseline reading.

Place several underpads under the woman's buttocks to absorb the fluid.

Position the woman on a padded bed pan, fracture pan, or rolled up towel to elevate her hips.

Assist the health care provider who is performing the procedure by providing sterile gloves and lubricant for the vaginal examination.

Unwrap sterile package containing Amnihook or Allis clamp and pass instrument to the primary health care provider, who inserts it alongside the fingers and then hooks and tears the membranes.

Reassess the FHR.

Assess the color, consistency, and odor of the fluid.

Assess the woman's temperature every 2 hours or per protocol.

Evaluate the woman for signs and symptoms of infection.


Record the following:

Time of rupture

Color, odor, and consistency of the fluid

FHR before and after the procedure

Maternal status (how well procedure was tolerated)


The presenting part of the fetus should be engaged and ell applied to the cervix to reduce the risk of cord prolapse (ACOG, 1995c; Summers, 1997). The membranes are ruptured with an Amnihook or other sharp instrument, and the amniotic fluid is allowed to drain slowly. The color, odor, and consistency of the fluid is assessed for the presence or absence of meconium or blood. The time of rupture is recorded.


NURSE ALERT The FHR is assessed before and immediately after the amniotomy to detect any changes (e.g., variable decelerations) that may indicate cord compression or prolapse.


The woman's temperature should be checked at least every 2 hours to rule out possible infection. If her temperature is 38° C or higher, the physician or nurse-midwife should be notified. The nurse assesses for other signs and symptoms of infection, such as maternal chills, fetal tachycardia, uterine tenderness on palpation, and foul-smelling vaginal drainage (Simpson & Poole, 1998). Comfort measures, such as frequently changing the woman's underpads, and perineal cleansing are implemented.

Oxytocin. Oxytocin is a hormone normally produced by the posterior pituitary gland; it stimulates uterine contractions. It may be used either to induce labor or to augment a labor that is progressing slowly because of inadequate uterine contractions.

The indications for oxytocin induction or augmentation of labor may include, but are not limited to, the following:

• Suspected fetal jeopardy (e.g., IUGR)

• Inadequate uterine contractions; dystocia

• Premature rupture of membranes

• Postterm pregnancy

• Chorioamnionitis

• Maternal medical problems (e.g., woman with severe Rh isoimmunization, diabetes, renal disease, or chronic pulmonary disease)

• Pregnancy-induced hypertension

• Fetal demise (death)

• Multiparous women with a history of precipitous labor or who live far from the hospital

The management of stimulation of labor is the same regardless of the indication. Because of the potential dangers associated with the injection of oxytocin in the prenatal and intrapartal periods, the FDA has issued certain restrictions to its use. Contraindications to oxytocin stimulation of labor include, but are not limited to, the following:

• CPD, prolapsed cord, transverse lie

• Nonreassuring FHR

• Placenta previa or vasa previa

• Prior classic uterine incision or uterine surgery

• Active genital herpes infection

• Invasive cancer of the cervix

Certain maternal and fetal conditions, although not contraindications to the use of oxytocin to stimulate labor, do require special caution during its administration. These conditions include the following:

• Multifetal presentation

• Breech presentation

• Presenting part above the pelvic inlet

• Abnormal FHR pattern not requiring emergency birth

• Polyhydramnios

• Grand multiparity

• Maternal cardiac disease; hypertension

Oxytocin use can present hazards to the mother and fetus. These hazards are primarily dose related, with most problems caused by high doses that are given rapidly. Maternal hazards include water intoxication and tumultuous labor with tetanic contractions, which may cause premature separation of the placenta, rupture of the uterus, lacerations of the cervix, or postpartum hemorrhage. These complications can lead to infection, disseminated intravascular coagulation, or amniotic fluid embolism. Women may become anxious or fearful if the induction is not successful because they may then have concerns about the method of birth.

Uterine hyperstimulation reduces the blood flow through the placenta and results in FHR decelerations (bradycardia, diminished variability, late decelerations), fetal asphyxia, and neonatal hypoxia. If the estimated date of birth is inaccurate, physical injury, neonatal hyperbilirubinemia, and prematurity are other hazards.

The physician or nurse-midwife writes the order for the induction or augmentation of labor with oxytocin. The nurse implements the order by initiating the primary intravenous infusion and administering the oxytocin solution through a secondary line. The nurse's actions related to assessment and care of a woman whose labor is being induced are guided by hospital protocol and professional standards (Fig. 8 and Box 10).

BOX 10 Protocol: Induction of Labor with Oxytocin


Explain technique, rationale, and reactions to expect:

• Route and rate for administration of medication

• What "piggyback" is for

• Reasons for use:

Induce labor, improve labor

• Reactions to expect concerning the nature of contractions: the intensity of contraction increases more rapidly, holds the peak longer, and ends more quickly; contractions will come regularly and more often

• Monitoring to anticipate:

Maternal: blood pressure, pulse, uterine contractions, uterine tone

Fetal: heart rate, activity

• Success to expect: a favorable outcome will depend on inducibility of the cervix (e.g., Bishop score of 9)

• Keep woman and support person informed of progress



Position woman in side-lying or upright position

Assess status of maternal fetal unit

Prepare solutions and administer with pump delivery system according to prescribed orders:

• Infusion pump and solution are set up (e.g., 10 U/1000 ml isotonic electrolyte solution)

• Piggyback solution is connected to IV line at proximal port (port nearest point of venous insertion)

• Solution with oxytocin is flagged with a medication label

• Begin induction at 0.5 to 2 mU/min

• Increase dose 1 to 2 mU/min at intervals of 15 to 60 minutes until a dose of up to 20 to 40 mU/min is reached


• Intensity of contractions results in intrauterine pressures of 40 to 90 mm Hg (shown by internal monitor)

• Duration of contractions is 40 to 90 seconds

• Frequency of contractions is 2- to 3-minute intervals

• Cervical dilation of 1 cm/hr in the active phase


• Monitor blood pressure, pulse, and respirations every 30 to 60 minutes and with every increment in dose

• Monitor contraction pattern and uterine resting tone every 15 minutes and with every increment in dose

• Assess intake and output; limit IV intake to 1000 ml/8 hr; output should be 120 ml or more every 4 hours

• Perform vaginal examination as indicated

• Monitor for nausea, vomiting, headache, hypotension

• Assess fetal status using electronic fetal monitoring; evaluate tracing every 15 minutes and with every increment in dose

• Observe emotional responses of woman and her partner


• Uterine hyperstimulation

• Nonreassuring FHR pattern

• Suspected uterine rupture

• Inadequate uterine response at 20 mU/min


Discontinue use of oxytocin per hospital protocol:

• Turn woman on her side

• Increase primary IV rate up to 200 ml/hr, unless patient has water intoxication, in which case, the rate is decreased to one that keeps the vein open

• Give woman oxygen by face mask at 8 to 10 L/min or per protocol or physician's or nurse-midwife's order


• Medication: kind, amount, time of beginning, increasing dose, maintaining dose, and discontinuing medication in patient record and on monitor strip

• Reactions of mother and fetus

• Notification of physician or nurse-midwife


In the past the aim of induction has been to achieve a contraction pattern that simulates the active phase of labor as quicldy as possible. However, research on uterine tolerance to oxytocin has shown that lower doses given over a longer time are as effective as previous protocols and are less likely to cause uterine hyperstimulation and dysfunctional labor (ACOG, 1995b; Simpson & Poole, 1998; Summers, 1997).

Nursing considerations. A written protocol for the preparation and administration of oxytocin should be established by the obstetric department (physicians, nurses) in each institution. One procedure recommended for a woman who is eligible for induction of labor is discussed in Box 10.


NURSE ALERT Oxytocin is discontinued immediately and the primary health care provider notified if uterine hyperstimulation or nonreassuring FHR (or both) occurs.


Other nursing interventions, such as administering oxygen by face mask, positioning the woman on her side, and infusing more intravenous fluids, are implemented immediately (see Emergency box). Based on the status of the maternal-fetal unit, the physician or nurse-midwife may order that the infusion be restarted once the FHR and uterine activity return to acceptable levels (ACOG, 1995b).





Uterine contractions lasting more than 90 seconds and occurring more frequently than every 2 minutes

Uterine resting tone greater than 20 mm Hg

Nonreassuring FHR:

Abnormal baseline (<110 or >160 beats/min)

Absent variability

Repeated late decelerations or prolonged decelerations


Maintain woman in side-lying position

Turn off oxytocin infusion; keep maintenance IV line open; increase rate

Start administering oxygen by face mask, per protocol or physician's order

Notify primary health care provider

Prepare to administer terbutaline (Brethine) 0.25 mg subcutaneously if ordered to decrease uterine activity

Continue monitoring FHR and uterine activity

Document responses to actions


Augmentation of labor

Augmentation of labor is usually implemented for the management of hypotonic uterine dysfunction resulting in a slowing of the labor process (protracted active phase). Common augmentation methods include oxytocin infusion, amniotomy, and nipple stimulation. Noninvasive methods such as emptying the bladder, ambulation and position changes, relaxation measures, nourishment and hydration, and hydrotherapy should be attempted before invasive interventions are initiated. The administration procedure and nursing assessment and care measures for augmentation of labor using oxytocin are similar to those used for induction of labor with oxytocin (Gilbert & Harmon, 1998; Pozaic, 1999; Simpson & Poole, 1998).

Some physicians advocate active management of labor, that is, the augmentation of labor to establish efficient labor with the aggressive use of oxytocin (e.g., a starting dose of 6 mU/min with increases of 6 mU/min every 15 minutes to a maximum dose of 40 mU/min) to shorten labor (ACOG, 1995c).

Additional components of the active management of labor include strict criteria to diagnose that the woman is in active labor with 100% effacement, amniotomy within 1 hour of admission of a woman in labor if spontaneous rupture of the membranes has not occurred, and continuous presence of a nurse who provides one-on-one care for the woman while she is in labor. When all components are fully implemented, active management of labor is associated with a lower incidence of cesarean birth (ACOG, 1995c). Active management of labor continues to be under study in the United States to determine effectiveness and impact on perinatal morbidity and mortality rates. Thus far results have been disappointing, especially in terms of a lack of reduction in the rate of cesarean birth. The disappointing results have been attributed, in part, to a greater than one-to-one nurse-patient ratio and the high rate of epidural anesthesia. It is considered to be a form of care of unknown effectiveness (Enkin et al., 2001; Gilbert & Harmon, 1998; Simpson & Poole, 1998).


Forceps-assisted birth

A forceps-assisted birth uses an instrument with two curved blades to assist in the birth of the fetal head. The cephalic-like curve of the forceps commonly used is similar to the shape of the fetal head, with a pelvic curve to the blades conforming to the curve of the pelvic axis. The blades are joined by a pin, screw, or groove arrangement. These locks prevent the forceps from compressing the fetal skull. Maternal indications for forceps-assisted birth include the need to shorten the second stage of labor in the event of dystocia or to compensate for the woman's deficient expulsive efforts (e.g., if she is tired or has been given spinal or epidural anesthesia) or to reverse a dangerous condition (e.g., cardiac decompensation).

Fetal indications include birth of a fetus in distress, certain abnormal presentations, arrest of rotation, or to deliver the head in a breech presentation. The use of forceps during childbirth has been decreasing. In 1999 forceps were used to assist 2.3% of births compared with 5.5% in 1989 (Ventura et al., 2001).

Certain conditions are required for a forceps-assisted birth to be successful. The woman's cervix must be fully dilated to avert lacerations and hemorrhage. The bladder should be empty. The presenting part must be engaged, and a vertex presentation is desired. Membranes must be ruptured so that the position of the fetal head can be determined and the forceps can firmly grasp the head during birth (Fig. 9). In addition, CPD should not be present.


Fig. 9 Outlet forceps-assisted extraction of the head.


Nursing considerations. The nurse obtains the type of forceps requested by the physician. The nurse may explain to the mother that the forceps blades fit like two tablespoons around an egg, with the blades coming over the baby's ears.


NURSE ALERT Because compression of the cord between the fetal head and the forceps would cause a drop in FHR, the FHR is assessed, reported, and recorded before and after application of the forceps.


If a drop in FHR occurs, the physician would then remove and reapply the forceps. Ordinarily, traction is applied during contractions.

After birth, the mother is assessed for vaginal and cervical lacerations (e.g., bleeding that occurs even with a contracted uterus); urine retention, which may result from bladder injuries; and hematoma formation in the pelvic soft tissues, which may result from blood vessel damage. The infant should be assessed for bruising or abrasions at the site of the blade applications, facial palsy resulting from pressure of the blades on the facial nerve (cranial nerve VII), and subdural hematoma. Newborn and postpartum caregivers should be told that the birth was forceps assisted.


Vacuum-assisted birth

Vacuum-assisted birth, or vacuum extraction, is a birth method involving the attachment of a vacuum cup to the fetal head, using negative pressure to assist in the birth of the head. Indications for its use are similar to those for outlet forceps. Prerequisites for use include a vertex presentation, ruptured membranes, and absence of CPD (Cunningham et al, 2001).

The rate of use of the vacuum extractor was 5.1% in 1999 (Ventura et al., 2001). When an operative vaginal birth is required, vacuum assistance is preferred as a more beneficial form of care than forceps assistance (Enkin et al., 2001).

When the birth is to be vacuum assisted, the woman is prepared for a vaginal birth in the lithotomy position to allow for sufficient traction. The cup is applied to the fetal head, and a caput develops inside the cup as the pressure is initiated (Fig. 10). Traction is applied to facilitate descent of the fetal head, and the woman is encouraged to push as suction is applied. As the head crowns, an episiotomy is performed if necessary. The vacuum cup is released and removed after birth of the head. If vacuum extraction is not successful, a forceps-assisted or cesarean birth is then performed.



Fig. 10 Use of vacuum extraction to rotate fetal head and assist with descent. A, Arrow indicates direction of traction on the vacuum cup. B, Caput succedaneum formed by the vacuum cup.


Risks to the newborn include cephalhematoma, scalp lacerations, and subdural hematoma. Fetal complications can be reduced by strict adherence to the manufacturer's recommendations for method of application, degree of suction, and duration of application. Maternal complications are uncommon but can include perineal, vaginal, or cervical lacerations and soft tissue hematomas.

Nursing considerations. The nurse's role for the woman who has a vacuum-assisted birth is one of support person and educator. The nurse can prepare the woman for birth and encourage her to remain active in the birth process by pushing during contractions. The FHR should be assessed frequently during the procedure. After birth, the newborn should be observed for signs of trauma and infection at the application site and for cerebral irritation (e.g., poor sucking or listlessness). The newborn may be at risk for cephalhematoma and neonatal jaundice as bruising resolves. The parents may need to be reassured that the caput succedaneum will begin to disappear in a few hours. Neonatal caregivers should be told that the birth was vacuum assisted.


Cesarean birth

The purpose of cesarean birth is to preserve the life or health of the mother and her fetus; it may be the best choice for birth when there is evidence of maternal or fetal complications. Since the advent of modern surgical methods and care, and the use of antibiotics, maternal and fetal morbidity and mortality rates have decreased. In addition, incisions are made into the lower uterine segment rather than into the muscular body of the uterus and thus promote more effective healing. However, despite these advances, cesarean birth still poses threats to the health of the mother and infant.

The incidence of cesarean births has increased from less than 5% in 1965 to 22% in 1999. Factors cited as sources of this increase include use of electronic fetal monitoring and epidural anesthesia; an increase in the number of firsttime pregnancies, as well as pregnancies at an older age; and the high incidence of repeat cesarean births. Between 1998 and 1999 the rate increased by 4%. This increase in cesarean birthrate is most likely associated with a decrease in the rate of vaginal birth after cesarean (VBAC). After increasing from 18.9% in 1989 to 28.3% in 1996, the rate of VBAC declined to 23.4% in 1999 (Guyer et al., 1998; Ventura et al., 2001).

Women 35 years of age and older had a cesarean birthrate of 30% in 1999, approximately twice the rate for women younger than 20 years of age (Ventura et al., 2001). Women who have private insurance, are of a higher socioeconomic status, or deliver in a private hospital are more likely to experience cesarean birth than are women who are poor, have no insurance, are receiving public assistance (e.g., Medicaid), or deliver in public hospitals (DiMatteo et al., 1996; Porreco & Thorp, 1996; Scott, 1999).

Approaches for the management of labor and birth to reduce the rate of cesarean birth and increase the rate of VBAC are presented in Box 11. These management approaches involve the combined efforts of health care professionals and pregnant women and their families (Flamm, Berwick, & Kabcenell, 1998; McNiven et al., 1998).


BOX 11 Selected Measures to Reduce Cesarean Birth Rate and Increase Rate of VBAC


• Advantages and safety of the home environment for early or latent labor

• Indicators for hospital admission

• Management techniques to use during labor to enhance progress

• Nonpharmacologic measures to reduce pain and discomfort and enhance relaxation

• Safety and effectiveness of TOL and VBAC


• Distinguish clinical manifestations for false labor, latent/ early labor, and active labor

• Conduct admission assessments in a separate admissions area

• Send women in false or early/latent labor home or keep them in the admissions area

• Admit women in active labor to the labor and birth unit


• Determine status of the maternal-fetal unit

• Establish an individualized rationale for initiating labor interventions such as epidural anesthesia, induction/ augmentation, amniotomy, cesarean birth


• Schedules admission during active labor

• Avoids automatic interventions such as routine induction for spontaneous rupture of membranes at term or postterm pregnancy and cesarean birth for breech presentation, twin gestation, genital herpes, or failure to progress

• Relies on assessment findings reflective of the status of the maternal-fetal unit rather than strict adherence to set ranges for the duration of the stages and phases of labor

• Employs intermittent rather than continuous electronic fetal monitoring of low risk pregnant women

• Focuses on measures that are known to enhance the progress of labor such as upright positions, frequent position changes, ambulation, oral nutrition and hydration, relaxation techniques, hydrotherapy

• Emphasizes nonpharmacologic measures to relieve pain

• Uses nonpharmacologic measures in a manner that reduces their labor-inhibiting effects

• Establishes criteria for elective cesarean birth and TOL

• Encourages women who have had a previous cesarean birth to participate in TOL to attempt a vaginal birth


The type of nursing care given may also influence the rate of cesarean births. Radin, Harmon, and Hanson (1993) found that cesarean rates were lower for women whose nurses provided supportive care during labor. A labor management approach that uses one-to-one support and emphasizes ambulation, maternal position changes, relaxation measures, oral fluids and nutrition, hydrotherapy, and nonpharmacologic pain relief facilitates the progress of labor and reduces the incidence of dystocia (Albers, Lydon-Rochelle, & Krulewitch, 1995; Porreco & Thorp, 1996). The labor management approach that most consistently reduced cesarean birthrate was one-to-one support of the laboring woman by another female such as a nurse, nurse-midwife, or doula (Cefalo & Bowes, 1998; Gabay & Wolfe, 1997).

Indications. There are few absolute indications for cesarean birth. Today, most cesarean births are performed primarily for the benefit of the fetus. The most common indications for cesarean birth are related to labor and birth complications. The complications most closely associated with cesarean birth include fetal distress, CPD, malpresentations such as breech and shoulder, placental abnormalities (previa, abruptio), umbilical cord prolapse, dysfunctional labor pattern, and multiple gestation. Medical risk factors most closely associated with cesarean birth include hypertensive disorders, active genital herpes, and diabetes (Porreco & Thorpe, 1996; Ventura et al, 2001).

Ethical consideration: forced cesarean birth. A woman's refusal to undergo cesarean birth for fetal reasons is often described as a maternal-fetal conflict. Health care providers are ethically obliged to protect the well-being of both the mother and the fetus; a decision for one affects the other. If a woman refuses a cesarean birth that is recommended because of fetal jeopardy, health care providers need to make every effort to find out why she is refusing and provide information that may persuade her to change her mind. If the woman continues to refuse surgery, health care providers must decide if it is ethical to get a court order for the surgery; however, every effort should be made to avoid this legal step.

Surgical techniques. The two main types of cesarean operation are the classic and the lower-segment cesarean incisions. Classic cesarean birth is rarely performed today, although it may be used when rapid birth is necessary and in some cases of shoulder presentation and placenta previa. The incision is made vertically into the upper body of the uterus (Fig. 11, A). Because the procedure is associated with a higher incidence of blood loss, infection, and uterine rupture in subsequent pregnancies than is lowersegment cesarean birth, vaginal birth after a classic cesarean birth is contraindicated.


Fig . 11 Cesarean birth; skin and uterine incisions. A, Classic: vertical incisions of skin and uterus. B, Low cervical: horizontal incision of skin; vertical incision of uterus. C, Low cervical: horizontal incisions of skin and uterus.


Lower-segment cesarean birth can be achieved through a vertical or transverse incision into the uterus (Fig. 11,B and C). The transverse incision is more popular because it is easier to perform, is associated with less blood loss and fewer postoperative infections, and is less likely to rupture in subsequent pregnancies (Cunningham et al., 2001; Scott, 1999).

Complications and risks. Cesarean births are not without complications, for both the mother and fetus. Maternal complications occur in 25% to 50% of births and include aspiration, pulmonary embolism, wound infection, wound dehiscence, thrombophlebitis, hemorrhage, urinary tract infection, injuries to the bladder or bowel, and complications related to anesthesia. There also is a risk that the fetus will be born prematurely if the gestational age has not been accurately determined; fetal injuries can occur during the surgery (Scott, 1999). Besides these risks, the woman is at economic risk because the cost of cesarean birth is higher than that of vaginal birth and a longer recovery period may require additional expenditures.

Following a cesarean birth, women may experience a delay in their ability to interact with their newborns after birth is delayed. These women are less likely to breastfeed and may even have some difficulty expressing positive feeling about their newborns for some time after birth. They are often less satisfied with their childbirth experience and report more fatigue and poor physical functioning during the first few weeks after discharge. These reactions are more pronounced among women who had unplanned or emergency cesarean birth (DiMatteo et al., 1996).

Anesthesia. Spinal, epidural, and general anesthetics are used for cesarean births. Epidural blocks are popular because women want to be awake for and aware of the birth experience. However, the choice of anesthetic depends on several factors. The mother's medical history or present condition, such as a spinal injury or hemorrhage, may rule out the use of regional anesthesia. Time is another factor, especially if there is an emergency and the life of the mother or infant is at stake. In such a case, general anesthesia will most likely be used unless an epidural block is already in place. The woman may not know all the options or may have fears about "a needle in her back" or of being awake and feeling pain. She needs to be fully informed about the risks and benefits of the different types of anesthesia so that she can participate in the decision whenever there is a choice.

Scheduled cesarean birth. Cesarean birth is scheduled or planned if labor is contraindicated (e.g., complete placenta previa), if birth is necessary but labor is not inducible (e.g., hypertensive states, which cause a poor intrauterine environment that threatens the fetus), or if this has been decided on by the physician and the woman (e.g., a repeat cesarean birth).

Women who are scheduled to have a cesarean birth have time to prepare for it psychologically. However, the psychologic responses of these women may differ. Those having a repeat cesarean birth may have disturbing memories of the conditions preceding the initial surgical birth and of their experiences in the postoperative recovery period. They may be concerned about the added burdens of caring for an infant and perhaps other children while recovering from a surgical operation. Others may feel glad that they have been relieved of the uncertainty about the date and time of the birth and to be free of the pain of labor.

Unplanned cesarean birth. The psychosocial outcomes of unplanned or emergency cesarean birth are usually more pronounced and negative in nature when compared with the outcomes associated with a scheduled or planned cesarean birth (DiMatteo et al., 1996). Women and their families experience abrupt changes in their expectations for birth, postbirth care, and the care of the new baby at home. This may be an extremely traumatic experience for all.

The woman usually approaches the procedure tired and discouraged after an ineffective and difficult labor. Fear predominates as she worries about her own safety and well-being and that of her fetus. She may be dehydrated, with low glycogen reserves. Because preoperative procedures must be done quickly and competently, the time for explanation of the procedures and operation is often short. Because maternal and family anxiety levels are high at this time, much of what is said may be forgotten or misunderstood. The woman may experience feelings of anger or guilt in the postpartum period. Fatigue is often noticeable in these women, and they need much supportive care.

After surgery, therefore, time must be spent reviewing the events preceding the operation and the operation itself to ensure that the woman understands what has happened and that gaps in her recollections are filled. This approach will help create more realistic memories of the childbirth experience, thereby having a more positive influence on future pregnancies and labors (Ryding, Wijma, & Wijma, 1998).

Whether cesarean birth is planned (scheduled) or unplanned (emergency), the loss of the experience of giving birth to a child in the traditional manner may have a negative effect on a woman's self-concept. An effort is therefore made to maintain the focus on the birth of a child rather than on the operative procedure.

Prenatal preparation. Concerned professional and lay groups in the community have established councils for cesarean birth to meet the needs of these women and their families. Such groups advocate that a discussion of cesarean birth be included in all parenthood preparation classes. No woman can be guaranteed a vaginal birth, even if she is in good health and there is no indication of danger to the fetus before the onset of labor. For this reason, every woman needs to be aware of and prepared for this eventuality.

Childbirth educators stress the importance of emphasizing the similarities and differences between a cesarean and vaginal birth. In support of the philosophy of family centered birth, many hospitals have instituted policies that permit fathers and other partners and family members to share in these births as they do in vaginal ones. Women who have undergone cesarean birth agree that the continued presence and support of their partners helped them respond positively to the entire experience. In addition to preparing women for the possibility of cesarean birth, childbirth educators should empower women to believe in their ability to give birth vaginally and to seek care measures during labor that will enhance the progress of their labors and reduce their risk for cesarean birth.

Preoperative care. Family-centered care is the goal for the woman who is to undergo cesarean birth and for her family. The preparation of the woman for cesarean birth is the same as that done for other elective or emergency surgery. The primary health care provider discusses, with the woman and her family, the need for the cesarean birth and the prognosis for the mother and infant. The anesthesiologist assesses the woman's cardiopulmonary system and describes the options for anesthesia. Informed consent is obtained for the procedure.

Blood and urine tests are usually done the day before a planned cesarean birth or on admission to labor. Laboratory tests, most commonly ordered to establish baseline data, include a complete blood cell count and chemistry, blood typing and crossmatching, and urinalysis. Maternal vital signs and blood pressure and FHR continue to be assessed per the hospital routine until the operation begins. Physical preoperative preparation usually includes inserting a retention catheter to keep the bladder empty and administering prescribed preoperative medications. An abdominal-mons shave or a clipping of pubic hair may be performed. An antacid, administered orally to neutralize gastric secretions in case of aspiration, is a beneficial form of care (Enkin et al., 2001). Intravenous fluids are started to maintain hydration and to provide an open line for the administration of blood or medications if needed.

Removal of dentures, nail polish, and jewelry may be optional, depending on hospital policies. If the woman wears glasses and is going to be awake, the nurse should make sure her glasses accompany her to the operating room so she can see her infant. If the woman wears contact lenses, the nurse can find out whether they can be worn for the birth.

During the preoperative preparation the support person is encouraged to remain with the woman as much as possible to provide continuing emotional support (if this action is culturally acceptable to the woman and support person). The nurse provides essential information about the preoperative procedures during this time. Although the nursing actions may be carried out quickly if a cesarean birth is unplanned, verbal communication, particularly explanations, is important. Silence can be frightening to the woman and her support person. The nurse's use of touch can communicate feelings of care and concern for the woman. The nurse can assess the woman's and her partner's perceptions about cesarean birth (e.g., the woman feels that she is a failure because she did not have a vaginal birth). If there is time before the birth, the nurse can teach the woman about postoperative expectations and about pain relief, turning, coughing, and deep-breathing measures.

Intraoperative care. Cesarean births occur in operating rooms in the surgical suite or in the labor and birth unit. Once the woman has been taken to the operating room, her care becomes the responsibility of the obstetric team, surgeon, anesthesiologist, pediatrician, and surgical nursing staff (Fig. 12). If possible, the partner, who is gowned appropriately, accompanies the woman to the operating room and remains close to her so that continued support and comfort can be provided.

C, A quick assessment is performed; note extreme molding of head resulting from cephalopelvic disproportion. (Courtesy Marjorie Pyle, RNC, Lifecircle, Costa Mesa, CA.)


The nurse who is circulating may assist with positioning the woman on the birth (surgical) table. It is important to position her so that the uterus is displaced laterally to prevent compression of the inferior vena cava, which causes decreased placental perfusion. This is usually accomplished by placing a wedge under the hip. A Foley catheter is inserted into the bladder at this time if one is not already in place.

If the partner is not allowed or chooses not to be present, the nurse can stay in communication with him or her and give progress reports whenever possible. If the woman is awake during the birth, the nurse or anesthesiologist, or both, can tell her what is happening and provide support. She may be anxious about the sensations she is experiencing, such as the coldness of solutions used to prepare the abdomen and pressure or pulling during the actual birth of the infant. She also may be apprehensive because of the bright lights or the presence of unfamiliar equipment and masked and gowned personnel in the room. Explanations by the nurse can help decrease the woman's anxiety.

Care of the infant usually is delegated to a pediatrician or a nurse team skilled in neonatal resuscitation, because these infants are considered to be at risk until there is evidence of physiologic stability after the birth.

A crib with resuscitation equipment is readied before surgery. Those responsible for care are expert not only in resuscitative techniques but also in their ability to detect normal and abnormal infant responses. After birth, if the infant's condition permits, the baby can be given to the woman's partner to hold. If the mother is awake, she can see and touch the baby (Fig. 13). The infant whose condition is compromised is transported after initial stabilization to the nursery for observation and the implementation of appropriate interventions. In some institutions the partner may accompany the infant; if not, personnel keep the family informed of the infant's progress and parentinfant contacts are initiated as soon as possible.

B, Parents become better acquainted with their newborn while mother rests after surgery. (Courtesy Marjorie Pyle, RNC, Lifecircle, Costa Mesa, CA.)


If the family cannot accompany the woman during surgery, the family is directed to the surgical or obstetric waiting room. The physician then reports on the condition of the mother and child to the family members after the birth is completed. Family members may accompany the infant as she or he is transferred to the nursery, giving them an opportunity to see and admire the new baby.

Immediate postoperative care. Once surgery is completed, the mother is transferred to a recovery room or back to her labor room. Women who have experienced a cesarean birth have both postoperative and postpartum needs that must be addressed. They are surgical patients, as well as new mothers (Eakes & Brown, 1998). Nursing assessments in this immediate postbirth period include degree of recovery from the effects of anesthesia, postoperative and postbirth status, and degree of pain. A patent airway is maintained, and the woman is positioned to prevent possible aspiration. Vital signs are taken every 15 minutes for 1 to 2 hours, or until stable. The condition of the incisional dressing, the fundus, and the amount of lochia are assessed, as well as the intravenous intake and the urine output through the Foley catheter. The woman is helped to turn and do coughing, deep-breathing, and leg exercises. Medications to relieve pain may be administered. If the baby is present, the mother and her partner are given some time alone with him or her to facilitate bonding and attachment. Breastfeeding can be initiated if the mother feels like trying. If the woman is in a recovery area, she usually is transferred to her postpartum room after 1 to 2 hours, or once her condition is stable and the effects of anesthesia have worn off (i.e., she is alert, oriented, and able to feel and move extremities) (see Care Path).

Postoperative/postpartum care. The attitude of the nurse and other health team members can influence the woman's perception of herself after a cesarean birth. The caregivers should stress that the woman is a new mother first and a surgical patient second. This attitude helps the woman perceive herself as having the same problems and needs as other new mothers while at the same time requiring supportive postoperative care.

The women's physiologic concerns for the first few days may be dominated by pain at the incision site and pain resulting from intestinal gas, and hence the need for pain relief. If epidural anesthesia was used for the surgery, epidural narcotics can be given in the recovery period to provide pain relief for approximately 24 hours. Otherwise, pain medications usually are given every 3 to 4 hours, or patientcontrolled analgesia may be ordered instead. Other comfort measures such as position changes, splinting of the incision with pillows, and relaxation techniques may be implemented. Women are often the best judges of what their bodies need and can tolerate, including the postoperative ingestion of foods and fluids. If desired by the woman, the early introduction of solid food is safe. Women who eat early have been found to require less analgesia and have fewer gastrointestinal problems (Burrows et al., 1995). Ambulation and rocking in a rocking chair may relieve gas pains, and avoiding the consumption of gas-forming foods and carbonated beverages may help minimize them (Thomas et al., 1990) (see Teaching Guidelines box).

Daily care includes perineal care, breast care, and routine hygienic care, including showering after the dressing has been removed (if showering is acceptable according to the women's cultural practices). The nurse assesses the woman's vital signs, incision, fundus, and lochia according to hospital policies, procedures, or protocols. Breath sounds, bowel sounds, circulatory status of lower extremities, and urinary and bowel elimination also are assessed. It is important to note maternal affect.

During the postpartum period the nurse can also provide care that meets the psychologic and teaching needs of mothers who have had cesarean births. The nurse can explain postpartum procedures to help the woman participate in her recovery from surgery. The nurse can help the woman plan care and visits from family and friends that will allow for adequate rest periods. Information on and assistance with infant care can facilitate adjustment to the mothering role. The woman is supported to breastfeed her baby by receiving individualized assistance to comfortably hold and position the baby at her breast. The partner can be included in infant teaching sessions and in explanations about the woman's recovery. The couple should also be encouraged to express their feelings about the birth experience. Some parents are angry, frustrated, or disappointed that a vaginal birth was not possible. Some women express feelings of low self-esteem or a negative self-image. Others express relief and gratitude that the baby is healthy and safely born. It may be helpful for them to have the nurse who was present during the birth visit and help fill in "gaps" about the experience. Other psychologic and lifestyle concerns that may occur after discharge include depression, feeling limited in activities, and changes in family interactions (Miovech et al., 1994; Ryding, Wijma, & Wijma,1998).

Discharge after cesarean birth is usually by the third postoperative day (Curtin & Kozak, 1998). The time is often determined by criteria established by the woman's insurance carrier or the federal government (e.g., diagnosisrelated groups).

The Newborn's and Mother's Health Protection Act of 1996 provides for a length of stay of up to 96 hours for cesarean births. These criteria may not coincide with the woman's physical or psychosocial readiness for discharge. Some states have added home care provisions for mothers who meet appropriate criteria for discharge and choose to leave sooner than the allowed length of stay. This policy recognizes that home care is less costly than hospital care and in most cases is more beneficial for recovery (Carpenter, 1998).

Eakes and Brown (1998) studied the expressed postdischarge needs of women who experienced planned and unplanned cesarean births. Findings revealed that the three predominant needs expressed by both groups of women were for rest and sleep; relief of pain and discomfort; and assistance with household chores, infant care and feeding, and self-care. Women who experienced planned cesarean births also expressed a need for help with depression, socialization, and family closeness, especially with regard to the limited amount of time they had to spend with their other children.

The nurse must provide discharge teaching to prepare women for self-care and newborn care in a limited time, while trying to ensure that the woman is comfortable and able to rest. The nurse should assess the woman's information needs and coordinate the health care team's efforts to meet them.

Discharge teaching and planning should include information about nutrition; measures to relieve pain and discomfort; exercise and specific activity restrictions; time management that includes periods of uninterrupted rest and sleep; hygiene, breast, and incisional care; timing for resumption of sexual activity and contraception; signs of complications (see Teaching Guidelines box and Self-Care box); and infant care. The nurse assesses the woman's need for continued support or counseling to facilitate her emotional recovery from the birth. The woman's family and friends should be educated regarding her needs during the recovery process, and their assistance should be coordinated before discharge. Referral to support groups or to community agencies may be indicated to further promote the recovery process. A postdischarge program of telephone follow-up and home visits can facilitate the woman's full recovery following cesarean birth.

Vaginal birth after cesarean

Indications for primary cesarean birth, such as dystocia, breech presentation, or fetal distress, often are nonrecurring. Therefore a woman who has had a cesarean birth may subsequently become pregnant and not have any contraindications to labor and vaginal birth in that pregnancy. ACOG (1999) encourages a TOL and VBAC attempt in women who have had one previous cesarean birth by low transverse incision. Vaginal birth is relatively safe, but there is a risk for uterine rupture through a lower uterine segment scar. Increased reports of uterine rupture in the United States and Canada in the 1990s have raised concerns about the safety of VBAC. Recommendations for the use of VBAC are being reevaluated (ACOG, 1999; Cunningham et al., 2001). Labor and vaginal birth are not recommended if there are contraindications, such as a previous fundal classic cesarean scar or evidence of CPD.

According to Scott (1999), 60% to 88% of women can give birth vaginally after a TOL. Women are most often the primary decision makers with regard to choice of birth method. During the antepartal period, the women should be given information about VBAC and encouraged to choose it as an alternative to repeat cesarean birth, as long as no contraindications exist. VBAC support groups and prenatal classes can help prepare the woman psychologically for labor and vaginal birth. Women need to believe not only that their efforts during a TOL will be successful but also that they are fully capable of doing what is necessary to give birth vaginally (self-efficacy) (Dilks & Beal, 1997).

This labor should occur in a hospital facility that has the equipment and personnel available to begin the surgery within 30 minutes from the time a decision is made to perform cesarean birth. Ideally, the woman is admitted to the labor and birth unit at the onset of spontaneous labor. In the latent phase of labor, the nurse encourages her to engage in normal activities such as ambulation. In the active phase of labor, FHR and uterine activity usually are monitored electronically and intravenous access such as a heparin lock may be established. The physician should be immediately available during active labor.

There is no evidence that administering oxytocin to induce or augment labor or the use of epidural anesthesia is contraindicated, although caution and close monitoring of the laboring woman is urged if these are used (Cunningham et al., 2001).

Attention should be paid to the woman's psychologic, as well as physical, needs during the TOL. Anxiety can inhibit the release of oxytocin, thus delaying the progress of labor and possibly leading to a repeat cesarean birth. To alleviate such anxiety, the nurse can encourage the woman to use breathing and relaxation techniques and to change positions to promote labor progress. The woman's partner can be encouraged to provide comfort measures and emotional support (Fawcett, Tulman, & Spedden, 1994). Collaboration among the woman in labor, the nurse, and other health care providers often results in a successful VBAC. If a TOL does not proceed to vaginal birth, the woman will need support and encouragement to express her feelings about having another cesarean birth.



Evaluation of the effectiveness of nursing care for a woman experiencing dystocia is based on the expected outcomes.



Shoulder dystocia is an uncommon obstetric emergency that increases the risk for fetal/neonatal and maternal morbidity and mortality during the attempt to deliver the fetus vaginally. Fetopelvic disproportion related to excessive fetal size (macrosomia) or maternal pelvic abnormalities may be a cause of shoulder dystocia (Hall, 1997; Wiznitzer, 1995). The fetus/newborn is more likely to experience birth injuries related to asphyxia, brachial plexus damage, and fracture, especially of the humerus or clavicle. The mother's primary risk stems from excessive blood loss as a result of uterine atony or rupture, lacerations, extension of the episiotomy, or endometritis. It is estimated that 0.23% to 2.09% of all vaginal births are complicated by shoulder dystocia (Bruner et al., 1998; Naef& Martin, 1995).



Many maneuvers such as suprapubic pressure and maternal position changes have been suggested and tried to free the anterior shoulder, although no one particular maneuver has been found to be most effective (Naef & Morrison, 1994). Suprapubic pressure can be applied to the anterior shoulder using the Mazzanti or Rubin technique (Fig. 14) in an attempt to push the shoulder under the symphysis pubis (Naef & Morrison, 1994). Having the woman move to a hands-and-knees position, a squatting position, or a lateral recumbent position has also been used to resolve cases of shoulder dystocia (Hall, 1997; Piper & McDonald, 1994).



Fig. 14 Application of suprapubic pressure. A, Mazzanti technique. Pressure is applied directly posteriorly and laterally above the symphysis pubis. B, Rubin technique. Pressure is applied obliquely posteriorly against the anterior shoulder.


In the McRoberts maneuver (Fig. 15), the woman's legs are flexed apart, with her knees on her abdomen (Piper & McDonald, 1994). This maneuver causes the sacrum to straighten and the symphysis pubis to rotate toward the mother's head; the angle of pelvic inclination is decreased, freeing the shoulder. The McRoberts maneuver is the preferred method when a woman is receiving epidural anesthesia. The Gaskin maneuver requires that the woman assume an all-fours position on her hands and knees (Bruner et al., 1998). It is proposed that the effects of a change in position along with the force of gravity and slight increase in pelvic diameters play a role in the maneuver's effectiveness. Fundal pressure is usually not advised as a method of relieving shoulder dystocia (Naef & Morrison, 1994; Piper & McDonald, 1994).


Fig. 15. McRoberts maneuver. (Modified from Gabbe, S., Niebyl, J., & Simpson, J. [2002]. Obstetrics: Normal and problem pregnancies [4th ed.]. New York: Churchill Livingstone.


The nurse helps the woman to assume the position(s) that may facilitate birth of the shoulders, assists the primary health care provider with these maneuvers and techniques during birth, and documents the maneuvers. The nurse also provides encouragement and support to reduce anxiety and fear.

Newborn assessment should include examination for fracture of the clavicle or humerus, brachial plexus injuries, and asphyxia (Hall, 1997). Maternal assessment should focus on early detection of hemorrhage.



Prolapse of the umbilical cord occurs when the cord lies below the presenting part of the fetus. Umbilical cord prolapse may be occult (hidden, not visible) at any time during labor whether or not the membranes are ruptured (Fig. 16, A and B). It is most common to see frank (visible) prolapse directly after rupture of membranes, when gravity washes the cord in front of the presenting part (Fig. 16, C and D). Contributing factors include a long cord (longer than 100 cm), malpresentation (breech), transverse lie, or unengaged presenting part.



Fig. 16 Prolapse of umbilical cord. Note pressure of presenting part on umbilical cord, which endangers fetal circulation. A, Occult (hidden) prolapse of cord. B, Complete prolapse of cord. Note that membranes are intact. C, Cord presenting in front of the fetal head may be seen in vagina. D, Frank breech presentation with prolapsed cord


If the presenting part does not fit snugly into the lower uterine segment (e.g., as in polyhydramnios), when the membranes rupture, a sudden gush of amniotic fluid may cause the cord to be displaced downward. Similarly, the cord may prolapse during amniotomy if the presenting part is high. A small fetus may not fit snugly into the lower uterine segment; as a result, cord prolapse is more likely to occur.



Prompt recognition of a prolapsed umbilical cord is important because fetal hypoxia resulting from prolonged cord compression (i.e., occlusion of blood flow to and from the fetus for more than 5 minutes) usually results in central nervous system damage or death of the fetus. Pressure on the cord may be relieved by the examiner putting a sterile gloved hand into the vagina and holding the presenting part off of the umbilical cord (Fig. 17, A and B). The woman is assisted into a position such as a modified Sims (Fig. 17, C), Trendelenburg, or knee-chest (Fig. 17, D) position, in which gravity keeps the pressure of the presenting part off the cord. If the cervix is fully dilated, a forceps- or vacuum-assisted birth can be performed for the fetus in a cephalic presentation; otherwise a cesarean birth is likely to be performed. Nonreassuring fetal status, inadequate uterine relaxation, and bleeding can also occur as a result of a prolapsed umbilical cord. Indications for immediate interventions are presented in the Emergency box. Ongoing assessment of the woman and her fetus is critical to determine the effectiveness of each action taken. The woman and her family are often aware of the seriousness of the situation; therefore the nurse must provide support by giving explanations for the interventions being implemented and their effect on the status of the fetus.

Notify primary health care provider immediately.

Glove the examining hand quickly and insert two fingers into the vagina to the cervix. With one finger on either side of the cord or both fingers to one side, exert upward pressure against the presenting part to relieve compression of the cord (Fig. 16, A and 6). Place a rolled towel under the woman's right or left hip.

Place woman into the extreme Trendelenburg or a modified Sims position (Fig. 16, C), or a knee-chest position (Fig. 16, D).

If cord is protruding from vagina, wrap loosely in a sterile towel saturated with warm sterile normal saline solution.

Administer oxygen to the woman by mask at 8 to 10 L/min until birth is accomplished.

Start IV fluids or increase existing drip rate.

Continue to monitor FHR by internal fetal scalp electrode, if possible.

Explain to woman and support person what is happening and the way it is being managed.

Prepare for immediate vaginal delivery if cervix is fully dilated or cesarean birth if it is not



Etiologic factors and clinical manifestations

Rupture of the uterus is a rare but very serious obstetric injury that occurs in 1 in 1500 to 2000 births. The most frequent causes of uterine rupture during pregnancy are separation of the scar of a previous classic cesarean birth, uterine trauma (e.g., accidents, surgery), and a congenital uterine anomaly. During labor and birth, uterine rupture may be caused by intense spontaneous uterine contractions, labor stimulation (e.g., oxytocin, prostaglandin), an overdistended uterus (e.g., multifetal gestation), malpresentation, external or internal version, or a difficult forceps-assisted birth. It occurs more commonly in multigravidas than in primigravidas (Varney, 1997).

A uterine rupture is classified as either complete or incomplete. A complete rupture extends through the entire uterine wall into the peritoneal cavity or broad ligament. An incomplete rupture extends into the peritoneum but not into the peritoneal cavity or broad ligament. Bleeding is usually internal. An incomplete rupture may also be a partial separation at an old cesarean scar and may go unnoticed unless the woman undergoes a subsequent cesarean  birth or other uterine surgery.

Signs and symptoms vary with the extent of the rupture and may be silent or dramatic. In an incomplete rupture, pain may not be present. The fetus may or may not have late decelerations, decreased variability, an increased or decreased heart rate, or other nonreassuring signs. The woman may experience vomiting, faintness, increased abdominal tenderness, hypotonic uterine contractions, and lack of progress. Eventually, bleeding and the effects of blood loss will be noted. Fetal heart tones may be lost. In a complete rupture the woman may complain of sudden, sharp, shooting abdominal pain and may state that "something gave way." If she is in labor, her contractions will cease and pain is relieved. She may exhibit signs of hypovolemic shock caused by hemorrhage (i.e., hypotension; tachypnea; pallor; and cool, clammy skin). If the placenta separates, the FHR will be absent. Fetal parts may be palpable through the abdomen. The nurse should suspect pulmonary embolism if the woman complains of chest pain (Varney, 1997).



Prevention is the best treatment. Women who have had a previous classic cesarean birth are advised not to attempt vaginal birth in subsequent pregnancies. Women at risk for uterine rupture are assessed closely during labor. Women whose labor is induced with oxytocin or prostaglandin (especially if their previous birth was cesarean) are monitored for signs of uterine hyperstimulation, because this can precipitate uterine rupture. If hyperstimulation occurs, the oxytocin infusion is discontinued or decreased and a tocolytic medication may be given to decrease the intensity of the uterine contractions. After giving birth, women are assessed for excessive bleeding, especially if the fundus is firm and there are signs of hemorrhagic shock.

If rupture occurs, the type of medical management depends on the severity. A small rupture may be managed with a laparotomy and birth of the infant, repair of the laceration, and blood transfusions, if needed. For a complete rupture, hysterectomy and blood replacement is the usual treatment.

The nurse's role may include starting intravenous fluids, transfusing blood products, administering oxygen, and assisting with the preparation for immediate surgery. Supporting the woman's family and providing information about the treatment are important during this emergency (Varney, 1997). The fetal mortality rate with rupture and expulsion into the peritoneal cavity is high (50% to 75%), and the maternal mortality rate may be high if the woman is not treated immediately (Cunningham et al., 2001). Providing information about spiritual support services or suggesting that the family contact their own support system may be warranted.



Amniotic fluid embolism (AFE) occurs when amniotic fluid containing particles of debris (e.g., vernix, hair, skin cells, meconium) enters the maternal circulation and obstructs pulmonary vessels, causing respiratory distress and circulatory collapse. This can occur because fluid can enter the maternal circulation any time there is an opening in the amniotic sac or maternal uterine veins, accompanied by enough intrauterine pressure to force the amniotic fluid into the veins (e.g., if the placenta separates or if there are rapid or strong contractions that cause the uterus to lacerate or rupture). Although uncommon, this complication is estimated to be the cause of 10% of maternal deaths in the United States. The fetal mortality rate is estimated to be as high as 50% (Martin, 1996; Martin & Leaton, 2001).

Amniotic fluid is more damaging if it contains meconium and other particulate matter such as mucus, fat globules, lanugo, bacterial products, or debris from a dead fetus because emboli can then form more readily. Maternal death occurs most often when thick meconium is present in the amniotic fluid because this clogs the pulmonary veins more completely than other debris. Even if death does not occur immediately, serious coagulation problems such as disseminated intravascular coagulopathy usually occur.

Maternal factors, including multiparity, tumultuous labor, abruptio placentae, and oxytocin induction of labor, and fetal problems, including macrosomia, death, and meconium passage, have been associated with an increased risk for the development of AFE (Cunningham et al., 2001; Martin, 1996).



The immediate interventions for AFE are summarized in the Emergency box. Such medical management must be instituted immediately. Cardiopulmonary resuscitation is often necessary. The woman is usually placed on mechanical ventilation, blood replacement is initiated, and coagulation defects are treated. Although the incidence of possible complications is small, their immediate recognition followed by prompt initiation of treatment is important.

The nurse's immediate responsibility is to assist with the resuscitation efforts. If the woman survives, she is usually moved to a critical care unit, where hemodynamic monitoring and blood replacement and coagulopathy treatment are implemented.

Support of the woman's partner and family is needed; they will be anxious and distressed. Brief explanations of what is happening are important during the emergency and can be reinforced after the immediate crisis is over. If the woman dies, emotional support and involvement of the perinatal loss support team or other resource for grief counseling are needed. Referral to grief and loss support groups would be appropriate (see Resources at end of Chapter 28). The nursing staff may also need help in coping with their feelings and emotions that result from a maternal death.
