Objectives: This study aimed to evaluate the feasibility of using a computerized machine to predict a successful normal vaginal delivery and determine the antepartum factors involved in failed labor induction in nulliparous term women. Methods: This prospective cohort study was conducted in Yas Hospital affiliated with Tehran University of Medical Sciences from 2017 to 2019. The data used for the computerized system were obtained during the admission of the term nulliparous women with singleton pregnancy in cephalic presentation. The cesarean delivery rate, as well as maternal and perinatal outcomes, were evaluated. The input variables were maternal age, gravida, gestational age at birth, necessity and type of labor induction, presentation of the baby at birth, Bishop Score, fetal weight, and fetal head circumference, and maternal disorders. The outputs were vaginal deliveries or cesarean sections. Results: The rate of cesarean section was 41.8% (n = 287). Higher maternal age (OR = 1.044, P = 0.018, CI = 1.007 - 1.082), lower Bishop Score (OR = 0.192, P < 0.001, CI = 0.139 - 0.256) and non-occiput anterior position (OR = 82.194, P < 0.001, CI = 15.888 - 425.214) were significantly associated with failed induction. Conclusions: The result of this study may be beneficial for healthcare providers to predict the delivery route, the risk of labor induction failure and make a personal decision according to each individual.

Objective Findings of the recent ARRIVE (A Randomized Trial of Induction Versus Expectant Management) trial, showing reduced cesarean risk with elective labor induction among low-risk nulliparous women at 39 weeks' gestation, have the potential to change interventional delivery practices but require examination in wider populations. The aim of this study was to identify whether term induction of labor was associated with reduced cesarean delivery risk among women with obesity, evaluating several maternal characteristics associated with obesity, induction, and cesarean risk. Study Design We studied administrative records for 66,280 singleton, term births to women with a body mass index ≥30, without a prior cesarean delivery, in New York City from 2008 to 2013. We examined elective inductions in 39 and 40 weeks' gestation and calculated adjusted risk ratios for cesarean delivery risk, stratified by parity and maternal age. We additionally evaluated medically indicated inductions at 37 to 40 weeks among women with obesity and diabetic or hypertensive disorders, comorbidities that are strongly associated with obesity. Results Elective induction of labor was associated with a 25% (95% confidence interval: 19–30%) lower adjusted risk of cesarean delivery as compared with expectant management at 39 weeks of gestation and no change in risk at 40 weeks. Patterns were similar when stratified by parity and maternal age. Risk reductions in week 39 were largest among women with a prior vaginal delivery. Women with comorbidities had reduced cesarean risk with early term induction and in 39 weeks. Conclusion Labor induction at 39 weeks was consistently associated with reduced risk of cesarean delivery among women with obesity regardless of parity, age, or comorbidity status. Cesarean delivery findings from induction trials at 39 weeks among low-risk nulliparous women may generalize more broadly across the U.S. obstetric population, with potentially larger benefit among women with a prior vaginal delivery.

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.

Successful Induction

Abstract Background Induction of labor is commonly performed in obstetric practice. Many methods have been suggested as good predictors of the outcome of labor induction, yet none of them is satisfactory enough. Objective To assess cervical length and uterocervical angle measured by transvaginal ultrasound as predictors of successful induction of labor. Methodology Prospective cohort study was conducted in a university-affiliated hospital over 150 nulliparous women undergoing induction of labor, in the period between May 2018 and August 2019. Transvaginal sonographic measurement of cervical length and uterocervical angle was done before induction of labor by prostaglandins. The patients were followed up till delivery and the outcome was recorded. Results The best cut-off value of cervical length for prediction of success of labor induction was 32.3 mm with 60% sensitivity and 56% specificity and the best cutoff value of uterocervical angle was 110.2 degrees with 87% sensitivity and 93% specificity. The cervical length showed a significant negative correlation while the uterocervical angle showed a significant positive correlation with the success of labor induction. Conclusion Cervical length and uterocervical angle are good predictors of successful labor induction.
