Most guidelines propose inducing labor within 24 h following term (37 or more weeks of gestation) prelabor rupture of membranes (PROM). However, the exact timing for initiating induction within the 24 h period remains unknown. This study aims to comparatively assess the efficacy and safety of the use of vaginal dinoprostone within 6 h versus within 6-24 h for singleton pregnancies with PROM and an unfavorable cervix (Bishop score < 6).
This was a retrospective cohort study including singleton pregnancies with PROM and an unfavorable cervix (Bishop score < 6) in which labor was induced using vaginal dinoprostone. Women were divided into two groups according to the timing of the use of induction (within 6 h versus within 6-24 h after PROM). Baseline maternal data, maternal and neonatal outcomes were recorded for statistical analysis.
450 women were included, 146 (32.4%) of whom were induced within 6 h of PROM and 304 (67.6%) were induced within 6-24 h. Cesarean delivery rate (15.8% versus 29.3%, p = 0.002) and nonreassuring fetal heart rate tracing (4.8% versus 10.5%, p = 0.043) in group with vaginal dinoprostone within 6 h were significantly lower than those in group with vaginal dinoprostone within 6-24 h. There was no significant differences in terms of duration from IOL to vaginal delivery.
Induction of labor within 6 h with vaginal dinoprostone after PROM for singleton pregnancies with an unfavorable cervix (Bishop score < 6) significantly associated with less cesarean section, less nonreassuring fetal heart rate tracing, compared to induction of labor within 6-24 h after PROM.
大多数指南建议在足月(妊娠 37 周或以上)胎膜早破(PROM)后 24 小时内引产。然而,在 24 小时内启动引产的确切时间仍不清楚。本研究旨在比较评估在宫颈条件不佳(Bishop 评分<6)的单胎妊娠 PROM 孕妇中,在 6 小时内与 6-24 小时内使用阴道普贝生引产的疗效和安全性。
这是一项回顾性队列研究,纳入了宫颈条件不佳(Bishop 评分<6)的单胎妊娠 PROM 孕妇,使用阴道普贝生引产。根据引产时机(PROM 后 6 小时内与 6-24 小时内)将孕妇分为两组。记录基线产妇数据、母婴结局进行统计学分析。
共纳入 450 例孕妇,其中 146 例(32.4%)在 PROM 后 6 小时内引产,304 例(67.6%)在 6-24 小时内引产。6 小时内使用阴道普贝生引产组的剖宫产率(15.8% vs. 29.3%,p=0.002)和非典型胎心监护率(4.8% vs. 10.5%,p=0.043)显著低于 6-24 小时内使用阴道普贝生引产组。两组从宫口扩张至阴道分娩的时间无显著差异。
对于宫颈条件不佳(Bishop 评分<6)的单胎妊娠 PROM 孕妇,在 PROM 后 6 小时内使用阴道普贝生引产与在 PROM 后 6-24 小时内引产相比,显著降低了剖宫产率和非典型胎心监护率。
