Objective Respiratory distress syndrome (RDS) is implicated in 30% of neonatal deaths. Since prostaglandins promote surfactant secretion and labor is associated with a lower risk of RDS in term neonates, it is plausible that synthetic prostaglandin (sPG) exposure is associated with a lower risk of RDS. Thus, we evaluated the association between sPG exposure and RDS in neonates born after the induction of labor (IOL). Study Design Secondary analysis of women with singleton pregnancies undergoing IOL at 340/7 to 420/7 weeks in the nuMoM2b study, a multicenter prospective cohort of nulliparous women. RDS rates and secondary neonatal outcomes in neonates with intrapartum sPG exposure were compared with those who had IOL with non-sPG methods (e.g., balloon catheter, amniotomy, oxytocin, and laminaria). Logistic regression models estimated the association of sPG with RDS and with secondary outcomes after adjustment for clinical and demographic factors (including gestational age). A sensitivity analysis was performed in which analysis was restricted to those with an admission cervical dilation ≤2 cm. Results Of 10,038 women in the total cohort, 3,071 met inclusion criteria; 1,444 were exposed and 1,627 were unexposed to sPGs. Antenatal corticosteroid exposure rates were low (3.0%) and similar between groups. In univariable analysis, neonates with sPG exposure had higher rates of RDS (3.2 vs. 2.0%, odds ratio [OR]: 1.59, 95% confidence interval [CI]: 1.01–2.50). This relationship was similar by gestational age at delivery (term vs. preterm, interaction p = 0.14). After adjustment, the association between sPG and RDS was no longer significant (adjusted odds ratio: 1.4, 95% CI: 0.9–2.3). When analysis was restricted to subjects with admission cervical dilation of ≤2 cm, there was also no association between sPG exposure and RDS. Conclusion In pregnancies between 34 and 42 weeks of gestation, exposure to sPG for cervical ripening or labor induction was not associated with newborn RDS. Key Points

Objective To evaluate for difference in outcomes between single- and double-balloon catheters for labor induction. Study Design We searched CINAHL, Embase, Cochrane Register, MEDLINE, ISI Web of Sciences, LILACs, and Google Scholar and retrieved studies through May 2017. Selection criteria included randomized controlled trials comparing single- versus double-balloon catheters. The primary outcome was time from catheter insertion to delivery. Heterogeneity of the results among studies was tested with the quantity I2 . For I2 values ≥50%, a random effects model was used to pool data across studies. Summary measures were reported as adjusted odds ratios (aORs) or as a mean difference (MD) with 95% confidence interval (CI). Results Four trials including a total of 682 patients were included: 340 patients were randomized to induction with a single-balloon catheter and 342 to induction with a double-balloon catheter. There was no significant difference between groups with respect to time to delivery (18.8 vs. 19.6 hours; MD: 0.40; 95% CI: –1.56 to 0.76), vaginal delivery rate (65.3 vs. 62.3%; aOR: 1.04; 95% CI: 0.56–1.92), cesarean delivery rate (25.6 vs. 27.5%; aOR: 0.98; 95% CI: 0.55–1.73), or epidural use (58.4 vs. 62%; aOR: 0.81; 95% CI: 0.56–1.18). Conclusion Double-balloon catheters have no apparent advantage over single-balloon catheters for labor induction.

Objective Evaluate the association between cervical examination after ripening with Foley catheter and labor induction outcomes. Materials and Methods In this retrospective cohort, nulliparous women with singleton, viable gestation undergoing cervical ripening with Foley catheter were compared based on cervical status after catheter removal or expulsion: favorable (modified Bishop score ≥ 5) or unfavorable (score < 5). Bivariable and multivariable analyses were performed to determine whether cervical examination postripening was associated with time to delivery and chance of vaginal delivery. Results A total of 774 women were eligible. Women with favorable examination postripening had lower body mass index (BMI) and more favorable admission cervical examination. The frequency of vaginal delivery was higher in women with favorable cervical examination postripening (57.9% versus 46.8%, p < 0.01). Median durations from Foley removal or expulsion to complete dilation (8.6 h versus 11.5 h) and vaginal delivery (10.4 h versus 13.2 h) were shorter for women with favorable cervical examination postripening (p < 0.001). In multivariable analysis, favorable examination postripening remained associated with vaginal delivery (adjusted odds ratio 1.39, 95% confidence interval 1.04–1.87), and time to vaginal delivery (adjusted hazard ratio 1.39, 95% confidence interval 1.13–1.70). Conclusion A favorable modified Bishop score after cervical ripening with Foley balloon catheter is associated with higher chance of vaginal delivery and shorter labor duration.

The aim of the study was to investigate if there are changes in elastographic parameters in the cervix at term around the time of delivery and if there are differences in the parameters between women with spontaneous labor and those without labor (labor induction). Nulliparous women at 36 weeks of gestation eligible for vaginal delivery were enrolled. Cervical elastography was performed and cervical length were measured using the E-CervixTM system (WS80A Ultrasound System, Samsung Medison, Seoul, Korea) at each weekly antenatal visit until admission for spontaneous labor or labor induction. E-Cervix parameters of interest included elasticity contrast index (ECI), internal os strain mean level (IOS), external os strain mean level (EOS), IOS/EOS strain mean ratio, strain mean level, and hardness ratio. Regression analysis was performed using days from elastographic measurement at each visit to admission for delivery and the presence or absence of labor against cervical length, and each E-Cervix parameter fitted to a linear model for longitudinal data measured repeatedly. A total of 96 women were included in the analysis, (spontaneous labor, n = 39; labor induction, n = 57). Baseline characteristics were not different between the two groups except for cesarean delivery rate. Cervical length decreased with advancing gestation and was different between the two groups. Most elastographic parameters including ECI, IOS, EOS, strain mean, and hardness ratio were significantly different between the two groups. In addition, ECI, IOS, and strain mean values significantly increased with advancing gestation. Our longitudinal study using ultrasound elastography indicated that E-cervix parameters tended to change linearly at term near the time of admission for delivery and that there were differences in E-Cervix parameters according to the presence or absence of labor.
