Maternal complications associated with multiple cesarean deliveries.

OBJECTIVE: The claim that a planned repeat cesarean delivery is safer than a trial of labor after cesarean may not be applicable to women who desire larger families. The aim of this study was to assess maternal complications after multiple cesarean deliveries. METHODS: The records of women who underwent two or more planned cesarean deliveries between 2000 and 2005 were reviewed. We compared maternal complications occurring in 277 women after three or more cesarean deliveries (multiple-cesarean group) with those occurring in 491 women after second cesarean delivery (second-cesarean group). RESULTS: Excessive blood loss (7.9% versus 3.3%; P < .005), difficult delivery of the neonate (5.1% versus 0.2%; P < .001), and dense adhesions (46.1% versus 25.6%; P < .001) were significantly more common in the multiple-cesarean group. Placenta accreta (1.4%) and hysterectomy (1.1%) were more common, but not significantly so, in the multiple-cesarean group. The proportion of women having any major complication was higher in the multiple-cesarean group, 8.7% versus 4.3% (P = .013), and increased with the delivery index number: 4.3%, 7.5%, and 12.5% for second, third, and fourth or more cesarean delivery, respectively (P for trend = .004). CONCLUSION: Multiple cesarean deliveries are associated with more difficult surgery and increased blood loss compared with a second planned cesarean delivery. The risk of major complications increases with cesarean delivery number. LEVEL OF EVIDENCE: II-2

The outcome of triplet, quadruplet, and quintuplet pregnancies managed in a perinatal unit: Obstetric, neonatal, and follow-up data

Multifetal gestation is associated with increased frequency of maternal complications and higher perinatal morbidity and mortality. The need for contemporary data on the outcome of multifetal gestations is further underscored when selective reduction is considered. The present study details the obstetric management, neonatal outcome, and follow-up data of 24 triplet, five quadruplet, and one quintuplet pregnancies delivered in a perinatal center. The early neonatal mortality rate was 31.6, the late neonatal mortality rate was 21, and the perinatal mortality rate was 51.5. Survival to discharge was 93%. The incidence of respiratory distress syndrome was 43%, bronchopulmonary dysplasia 6%, retinopathy of prematurity 3%, intraventricular hemorrhage 4%, and cerebral palsy 2%. Follow-up from 1 to 10 years shows that only one child is moderately handicapped, whereas 99% have no significant medical problem. Early diagnosis by ultrasonography, meticulous antenatal care, early hospitalization, delivery by cesarean section, and on-site availability of a neonatologist for each baby at the time of delivery are the probable major determinants of improved outcome.

Ehlers-Danlos syndrome: insights on obstetric aspects.

Ehlers-Danlos syndrome (EDS) is a heterogeneous group of connective tissue disorders characterized by joint hypermobility, skin hyperelasticity, tissue fragility, easy bruising, and poor healing of wounds. The clinical manifestations vary depending on the type of disease. The syndrome may be associated with a number of pregnancy and peripartum complications. Because of the multi-organ involvement and varied presentation of this disease, no uniform or routine obstetric and anesthetic recommendations can be made for the perinatal care of these patients. We present a review of the literature on EDS with emphasis on the obstetric, anesthetic, and perinatal consequences. We also report our experience with this syndrome: an uneventful term vaginal delivery in a 32-year-old woman diagnosed with hypermobility type of EDS. Target Audience: Obstetricians & Gynecologists, Family Physicians Learning Objectives: After completion of this article, the reader should be able to recall the potentially severe nature of Ehlers-Danlos Syndrome (EDS) in both pregnant and nonpregnant patients, summarize the wide range of signs and symptoms and its genetic inheritance, and explain the difficulty in recommending obstetric and anesthesia procedures to avoid complications.

Early Second-Trimester Low Umbilical Coiling Index Predicts Small-for-Gestational-Age Fetuses

To evaluate the role of the early second‐trimester Doppler velocimetric studies of the umbilical coiling index and umbilical cord cross‐sectional area as tests for the prediction of small‐for‐gestational age infants.

Elevated liver enzymes and thrombocytopenia in the third trimester of pregnancy: An unusual case report and a review of the literature

A woman presented in the third trimester of pregnancy with epigastric pain, elevated liver enzymes, and thrombocytopenia. The frozen-section liver biopsy findings were compatible with acute fatty liver of pregnancy. The light and electron microscopic findings were those of preeclampsia. All clinical and laboratory abnormalities resolved before delivery.

Prediction of lethal pulmonary hypoplasia and chorioamnionitis by assessment of fetal breathing

Summary. Twenty‐three pregnancies with fetuses at risk for pulmonary hypoplasia were studied weekly until delivery. The amount of time spent in fetal breathing activity was recorded under controlled conditions during 1 h using real‐time ultrasound. An amniotic fluid index was determined. The clinicians and the pathologist were unaware of the ultrasound findings. Eight of 23 fetuses did not breathe at the last ultrasound examination. Three babies died of pulmonary hypoplasia and two of these showed fetal breathing before birth. The three deaths were associated with rupture of the membranes at <20 weeks gestation and of ≥44 days duration. One infant developed bronchopulmonary dysplasia. The amniotic fluid index in these four pregnancies was low and the newborn infants had limb contractures. Chorioamnionitis/funisitis was noted in 13 placentas. Eight fetuses were assessed for fetal breathing within 2 days of birth. The lack of fetal breathing had sensitivity, specificity, positive and negative predictive values of 0.75 for chorioamnionitis/funisitis. In this pilot study the absence of fetal breathing was of no value in predicting lethal pulmonary hypoplasia, but was related to chorioamnionitis/funisitis. We recommend further studies of fetal breathing in relation to fetal/neonatal infections.

Results of a well-defined protocol for a trial of labor after prior cesarean delivery.

OBJECTIVE: It has been claimed that a trial of labor after cesarean carries higher maternal and fetal risks than planned cesarean delivery. Because the management of such patients in our department differs from that described in some studies, and is perhaps more cautious, we hypothesized that the outcome may be better. METHODS: We identified women with 1 previous low uterine segment cesarean who had delivered a cephalic singleton infant at gestational age 34 weeks or more from January 2000 through May 2005. Our policy is to encourage such women to undergo a trial of labor unless cesarean delivery is indicated. Unless otherwise indicated, our policy is to wait for spontaneous labor. We do not use prostaglandins, and recommend cesarean delivery if the cervix is unripe.(Bishop score < 6). We compared the outcome between women who underwent a trial of labor and women who underwent planned cesarean delivery. RESULTS: A trial of labor was attempted by 841 women (80% successful), and 467 underwent planned cesarean delivery. Uterine rupture was observed in 1 woman 18 hours after vaginal delivery. There was no difference in major or minor maternal morbidity. There was no serious neonatal morbidity. Among the planned cesarean patients, hospital stay was longer, and there were more admissions to the neonatal intensive care unit. CONCLUSION: With our well-defined protocol, a trial of labor after cesarean seems to be as safe for the mother and infant as planned cesarean delivery, and the hospital stay is shorter.

Pregnancy exacerbating hepatopulmonary syndrome.

BACKGROUND: Hepatopulmonary syndrome is an uncommon complication of liver cirrhosis. The natural history of this condition and its optimal management during pregnancy are not yet known. CASE: We present the case of a 35-year-old woman with liver cirrhosis who developed severe dyspnea in the 25th week of gestation and was diagnosed as suffering from hepatopulmonary syndrome. She was managed conservatively until 35 weeks of gestation, when she was delivered by cesarean. CONCLUSION: The natural history, in this case, indicates that pregnancy may induce hepatopulmonary syndrome in an otherwise asymptomatic cirrhotic patient. Oxygen supplementation was the cornerstone of treatment and resulted in a favorable outcome.

Fetal heart rate patterns and neurodevelopmental outcome in very low birth weight infants

Background. To evaluate the validity of fetal heart rate monitoring during the last hour prior to birth, as a predictor of long term neurodevelopmental outcome of very low birth weight infants. Methods. A total of 111 very low birth weight infants were included in the study. Fetal heart rate tracings were obtained during the last hour prior to delivery. A perinatologist, blinded to the neonatal outcome, evaluated the tracings and divided them into three groups: reassuring, nonreassuring, and pathological. Neurodevelopmental status was evaluated at age 2 years. The relationship between fetal heart rate monitoring results and the neurodevelopmental outcome at 2 years of age was assessed with a chi‐square test and the Students t‐test. Results. At 2 years of age 97 (87.4%) of the children had normal neurodevelopmental function, while 14 (12.6%) had variable degrees of neurodevelopmental impairment. The fetal heart rate monitoring results were classified as reassuring (normal) in 35 cases (31.5%), nonreassuring in 56 cases (50.5%), and pathological in 20 cases (18.0%). Both normal and pathological fetal heart rate patterns were associated with similar incidence of abnormal neurodevelopmental outcome, 14.3% and 15.0% of cases, respectively (p=0.778). Pathological fetal heart rate patterns as a predictor of neurodevelopmental outcome had a sensitivity of 27%, specificity of 74%, positive predictive value of 15%, and negative predictive value of 86%. Conclusion. Electronic fetal heart rate monitoring prior to delivery is not a reliable tool for the prediction of neurodevelopmental impairment in premature infants of very low birth weight, at 2 years of age.
