Is Induction of Labor with Early Rupture of Membranes Associated with an Increased Rate of Clinical Chorioamnionitis?

Objective: The objective of this study was to determine if early rupture of membranes (ROM) in women undergoing induction of labor (IOL) at term is associated with an increased rate of clinical chorioamnionitis. Study Design: A retrospective cohort study was performed on women undergoing IOL. Early ROM was defined as ROM at a modified Bishop score less than 5, cervical dilation less than 4 cm, or cervical effacement less than 80%. The rate of clinical chorioamnionitis was compared between women with early and late ROM. Results: The rate of clinical chorioamnionitis was 8.6% (24/279). ROM at an effacement of less than 80% was associated with a rate of clinical chorioamnionitis of 15.4% (12/78) compared to 6.0% (12/201) at an effacement of equal to or greater than 80%, p = 0.017. The rate of cesarean delivery was higher for patients with early ROM by any definition: 32% compared to 17.5% by modified Bishop score (p = 0.031), 32.4% versus 18.2% by cervical dilation (p = 0.049), and 33.3% versus 14.9% by cervical effacement (p = 0.001). Conclusions: In patients undergoing IOL, early ROM may be associated with an increased rate of clinical chorioamnionitis when performed at a cervical effacement of less than 80% and an increased rate of cesarean delivery.

The Efficacy and Safety of Dinoprostone Vaginal Insert for Labor Induction Following Optimization of Standard Operating Procedure: A Retrospective Study in China

Background:The study aimed to assess the efficacy and safety of dinoprostone vaginal insert in labor induction following optimization of standard operating procedure(SOP)and to discover independent predictors of vaginal delivery.Methods:This study comprised 551 pregnant women who required cervical ripening with dinoprostone before induction of labor.Using univariate and multivariate analyses,independent predictors of vaginal delivery were identified.Results:443 of the 551 women(80.4%)gave birth vaginally.Vaginal delivery was predicted by maternal age(24-30 vs.<24,P<0.001;30-35 vs.<24,P=0.03),gestational age(P=0.005),birth weight(P<0.001),parity(P=0.001),pre-pregnancy BMI(P<0.001),premature rupture of membranes(P=0.001),meconium-stained amniotic fluid(P<0.001),fundal height(P<0.001)and the Bishop score(P<0.001).None of the women exhibited severe postpartum hemorrhage.Conclusions:The maternal age,gestational age,birth weight,parity,body mass index,premature membrane rupture,amniotic fluid contamination,fundal height,and the Bishop score were independent predictors of vaginal delivery.These may guide the clinical use of dinoprostone for induction of labor.

Effectiveness of Dinoprostone and Cook's Balloon for Labor Induction in Primipara Women at Term

Labor induction is commonly used for achieving successful vaginal delivery.This study aimed to compare the effectiveness of dinoprostone and Cook's balloon as labor-inducing agents in primipara women at term.A retrospective cohort study among primipara women was conducted in Hubei Maternity and Child Health Hospital.Basic clinical characteristics were collected.The main outcomes were vaginal delivery rate,cesarean section rate and forceps delivery rate.Obstetric and perinatal outcomes were also compared.Univariate and multivariate analyses were further performed to evaluate the predictors for vaginal delivery within 24 h.A total of 845 eligible primipara women undergoing labor induction were recruited.Of them,141 women were induced with dinoprostone(dinoprostone group,DG),and 704 with Cook's balloon(Cook's balloon group,CG).Groups were homogeneous except more women with premature rupture of membranes in DG,with gestational hypertension in CG(P<0.05).The vaginal delivery rate within 12 h was 1.98%and 16.52%in CG and DG respectively(P=0.0001).Besides,the vaginal delivery rate within 24 h was 37.62%and 52.26%in CG and DG respectively(P=0.0079).DG showed the lower rate of oxytocin augmentation,artificial rupture of membrane and postpartum hemorrhage and the shorter interval from insertion to active labor than CG(P<0.05).Multivariate regression analysis revealed that abortion history,oxytocin augmentation,artificial rupture of membrane,and obstric analgesia were independent predictors for vaginal delivery within 24 h.In conclusion,dinoprostone was more effective than Cook's balloon to induce labor and achieve vaginal birth in the sample of primipara women at term.

Effects of two different protocols of oxytocin infusion for labor induction on obstetric outcomes: A cohort study

Objective: Concerns remain about the safety and efficacy of high dose and low dose protocols of oxytocin for labor induction. We have compared 2 regimens of oxytocin induction (low-dose vs high dose) on perinatal outcomes over a 1-year period. Study Design: Included were all women undergoing induction of labor at term with live singleton gestations. Cesarean delivery (CD) and a composite adverse neonatal outcome (5-min Apgar score < 7, umbilical artery pH < 7.10, or need for admission to NICU) were assessed using logistic regression analysis. Admission-to-delivery intervals was compared between the two groups by log-rank test. Results: A total of 544 women fulfilled the study criteria. The two groups were comparable for demographic and obstetric variables. There was no significant association between oxytocin regimen and rates of CD (P = 0.77) or adverse neonatal outcome (P = 0.99) even after controlling for confounders. The admission-to-delivery interval was significantly shorter for the high-dose group than for the low-dose group (median interval = 11.7 vs 14.3 hours, respectively, P = 0.026). Conclusion: Use of a high-dose protocol of oxytocin administration for induction of labor at term is associated with similar rates of cesarean section and adverse neonatal outcome as a low-dose protocol, but with an average of 2.5 hours shorter duration of labor.

Spontaneous versus Induced Labor Delivery, a Retrospective Analysis

Background: Induction of labor is the stimulation of the uterus to initiate the labor process whether by administering oxytocin, prostaglandin or reputing the membrane [1]. It was realized that the number of induction of labor patients was thought to be increasing in comparison with the spontaneous labor patients. Therefore, the complications of induced labor were higher. A detailed analysis was needed to confirm that. Objective: The aim of the study is to analyze the outcomes between spontaneous versus induced labor. Materials and Methods: A retrospective analysis was conducted at our tertiary care university hospital, in the period from December 2015 to December 2016 when 311 women were divided into two groups: group 1, women who had spontaneous labor (n = 106) compared with group 2, women who were labor induced (n = 205). Complications of pregnancy, delivery type, tear, episiotomy, blood transfusion and instruments used were analyzed retrospectively. Results: The mean ± SD of baseline characteristics, like age, height, weight, BMI and hemoglobin level for all study samples was 28.59 ± 5.95 years, 1.58 ± 0.06 m, 71.77 ± 13.42 kg, 28.59 ± 5.89 kg/m2 and 11.08 ± 1.45 g/dl respectively. A statistically significant difference was noticed in the duration of labor between spontaneous and induced labor (95% CI: 9.194 - 152.130;p-value 0.004 and OR: 0.239). There was no significant difference in complications, delivery type (Spontaneous Vaginal Delivery (SVD) or other), blood transfusion, and instrument used between women who had spontaneous labor versus induced labor. However, significant differences in tear (95% CI: 4.354 - 0.996;p-value 0.035) and episiotomy (95% CI: 0.928 - 0.224;p-value 0.028) were found between the two groups. In conclusion, the induced labor was found to be associated with high incidence of duration of labor, tear and episiotomy. Patients should always be counseled when there it is an option between the two delivery types.

Efficacy and Safety of Misoprostol Vaginal Insert to Induce Labor beyond 40 + 0 Weeks of Gestation

Objective: Misoprostol vaginal insert (MVI) is proven to induce labor by a continuously release of PGE1. Previous reports showed that MVI reduced induction to delivery time as well as active labor time but it also increased uterine tachysystole. Here we attempted to clarify whether MVI is safe and efficient for women with pregnancies >40 weeks in a single institute. Methods: This study was performed in Lutheran Hospital Bergisch Gladbach, Germany 2014-2019. A total of 304 women between 40 + 0 to 42 + 0 weeks underwent labor induction with MVI. Outcomes were: 1) maternal: time from insertion to delivery, interventions, mode of delivery, and uterine tachysystole, 2) neo-natal: cord blood pH, APGAR scores, and admission to a neonatal clinic. This study ended unexpectedly due to the withdrawal of MVI (MisodelTM) in September 2019. Results: 75.7% (n = 230) of women gave birth within 24 hours after MVI placement. 72.2% (n = 140) nulliparous women and 81.8% (n = 90) parous women delivered within 24 hours. In two cases emergency CS was required. 67.8% (n = 206) of women delivered vaginal. 2.3% (n = 7) of cord pH levels were below 7.10. 3.3% (n = 10) of newborns were transmitted to a neonatal clinic. Conclusion: MVI is an efficient method to induce labor for pregnant women beyond 40 + 0 weeks. However, considering various complications observed (uterine tachysystole and fetal distress leading to a high number of CS), we cannot universally advocate the use of MVI.

产程进展角对妊娠晚期引产结局的预测价值

目的探讨经会阴超声(TPU)测量产程进展角(AOP)对妊娠晚期引产结局的预测价值。方法选取2020年4月至2021年2月在南京大学医学院附属鼓楼医院住院引产的单胎足月初产妇共106例。引产前,由一位高年资产科医生行宫颈Bishop评分,由另一位高年资产科医生采用TPU测量引产前产妇的AOP。纳入宫颈Bishop评分<6分的产妇,对其均采用欣普贝生引产,根据最终的分娩方式,将其分为阴道分娩组(84例)与剖宫产组(22例),比较两组的AOP,并绘制受试者工作特征(ROC)曲线,寻找预测阴道分娩的AOP最佳临界值。结果引产前,阴道分娩组的AOP明显大于剖宫产组[(100.4±11.6)°vs.(88.3±9.8)°],差异具有统计学意义(t=4.486,P<0.05);阴道分娩组的引产一分娩时间明显短于剖宫产组[1473.5(942.3,2175.8)min vs.1910.0(1599.0,2614.0)min],差异具有统计学意义(Z=-2.750,P<0.05)。当除去非产程因素剖宫产后分析显示,AOP临界值为89°;当引产前AOP>89°时,产妇能经阴道分娩的阴性预测值为96.1%,灵敏度为80.0%,特异度为86.9%。结论AOP可作为初产妇引产成功(阴道分娩)的预测指标,当AOP>89°时,引产后阴道分娩成功率高。
