Background: Fetal myelomeningocele (fMMC) repair has become accepted as a standard of care option in selected circumstances. We reviewed our outcomes for fMMC repair from referral and evaluation through surgery, delivery and neonatal discharge. Material and Methods: All patients referred for potential fMMC repair were reviewed from January 1, 2011 through March 7, 2014. Maternal and neonatal data were collected on the 100 patients who underwent surgery. Results: 29% of those evaluated met the criteria and underwent fMMC repair (100 cases). The average gestational age was 21.9 weeks at evaluation and 23.4 weeks at fMMC repair. Complications included membrane separation (22.9%), preterm premature rupture of membranes (32.3%) and preterm labor (37.5%). Average gestational age at delivery was 34.3 weeks and 54.2% delivered at ≥35 weeks. The perinatal loss rate was 6.1% (2 intrauterine fetal demises and 4 neonatal demises); 90.8% of women delivered at the Children's Hospital of Philadelphia and 3.4% received transfusions. With regard to the neonates, 2 received ventriculoperitoneal shunts prior to discharge; 71.1% of neonates had no evidence of hindbrain herniation on MRI. Of the 80 neonates evaluated, 55% were assigned a functional level of one or more better than the prenatal anatomic level. Conclusion: In an experienced program, maternal and neonatal outcomes for patients undergoing fMMC repair are comparable to results of the MOMS trial.

To determine whether the effectiveness of oxytocin treatment of arrest of dilatation differed in obese compared to lean women, we did a retrospective analysis of 118 subjects in spontaneous labor whose arrest of dilatation was treated with oxytocin. Cases were stratified by maternal body mass index (BMI): Group A, <25 kg/m2; Group B, 25.0-29.9 kg/m2; Group C, 30.0-34.9 kg/m2; and Group D, ≥ 35 kg/m². Groups were comparable in maternal age, parity, gestational age, birth weight, and the frequency of infection. Full dilatation was reached in about 90% of Group A and B, 72% of Group C, and 39% of Group D, the most obese women (P<0.001). The cesarean rate was directly related to maternal BMI, 11.4%, 22.9%, 34.3%, and 69.6% in Groups A through D, respectively (P<0.001). Significantly more oxytocin was used in group D than in the other groups during the first 3h of infusion in attempting to overcome the arrest (P=0.003). We conclude that oxytocin treatment of arrest of dilatation was less effective in obese than in lean women. This effect was most prominent in women with a BMI >35 kg/m2, who were, despite having received more oxytocin than those in the leaner groups, less than half as likely to attain full dilatation and more than twice as likely to deliver by cesarean.

<b><i>Aim:</i></b> The optimal gestational age (GA) at delivery and mode of delivery (MoD) for pregnancies with fetal congenital diaphragmatic hernia (CDH) is undetermined. The impact of early term (37–38 weeks 6 days) versus full term (39–40 weeks 6 days) and MoD on immediate neonatal outcomes in prenatally diagnosed isolated CDH cases was evaluated. <b><i>Material and Methods:</i></b> A retrospective chart review of pregnancies evaluated and delivered with the prenatal diagnosis of CDH between July 1, 2008, and December 31, 2018. The primary outcome was survival to hospital discharge. Secondary outcomes included neonatal intensive care unit (NICU) length of stay (LOS), extracorporeal membrane oxygenation (ECMO) requirement and need for supplemental oxygen at day 30 of life. <b><i>Results:</i></b> A total of 296 patients were prenatally evaluated for CDH and delivered in a single center during the study period. After applying exclusion criteria, data were available on 113 women who delivered early term and 72 women who delivered full term. Survival to hospital discharge was comparable between the 2 groups – 83.2% in the early term versus 93.1% in the full term (<i>p</i> = 0.07; 95% CI of 0.13–1.04). No difference was observed in any other secondary outcomes. MoD was stratified into spontaneous vaginal, induced vaginal, unplanned cesarean and scheduled cesarean delivery with associated neonatal survival rates of 74.2, 90.6, 89.7 and 88.2%, respectively, <i>p</i> = 0.13. The 5-min Apgar score was higher in the elective cesarean group (7.94) followed by the induced vaginal delivery group (7.8) compared to 7.17 and 7.18 in the spontaneous vaginal and unplanned cesarean groups, respectively (<i>p</i> = 0.03). The GA and MoD did not influence survival to hospital discharge nor NICU LOS in multivariate analysis. <b><i>Conclusions:</i></b> Though there were no significant differences in neonatal outcomes for early term compared to full term deliveries of CDH neonates, a trend toward improved survival rates and lower ECMO requirements in the full term group may suggest an underlying importance GA at delivery. Further studies are warranted to validate these findings.
