小剂量缩宫素引产失败后高位人工破膜对催产效果评估
Evaluation of the effect of high artificial rupture of membranes following failed low-dose oxytocin induction
目的 探讨水囊联合小剂量缩宫素引产2~3 d无效后,行高位人工破膜对孕妇催产效果及母婴结局的影响。 方法 选取2020年1月至2023年12月在我院具有引产指征、经水囊联合小剂量缩宫素引产2~3 d无效的50例孕妇,分为对照组(n=24)与观察组(n=26)。对照组继续缩宫素静脉滴注或行剖宫产终止妊娠;观察组于高位人工破膜1 h后继续缩宫素静脉滴注。比较2组宫颈Bishop评分、总产程时间、剖宫产率、产后出血量、产后感染率、新生儿Apgar评分及产时并发症(如胎盘早剥、胎儿宫内窘迫)等指标。 结果 观察组剖宫产率为30.77%,显著低于对照组的100.00%(P<0.05)。相比于对照组,观察组产后出血量更少(P<0.05),总产程时间更短(P<0.05),新生儿Apgar评分更低(P<0.05)。2组在羊水性状、产后感染率及产时并发症等方面差异无统计学意义(P>0.05)。 结论 对于水囊联合小剂量缩宫素引产无效、宫颈Bishop评分<6分的孕妇,采用高位人工破膜可有效促进产程进展,提高阴道分娩率,降低剖宫产率,且对母婴安全性良好,具有积极的临床意义。
Objective To evaluate the efficacy of high artificial rupture of membranes and its impact on maternal and neonatal outcomes after failure of induction with a water balloon combined with low-dose oxytocin. Methods From January 2020 to December 2023, a total of 50 pregnant women who had indications for labor induction and experienced failed induction after 2-3 days of using a cervical ripening balloon combined with low-dose oxytocin in our hospital were selected. They were divided into a control group (n=24) and an observation group (n=26). The control group continued oxytocin infusion or underwent cesarean section, while the observation group received high AROM followed by oxytocin infusion after one hour. Cervical Bishop score, total labor duration, cesarean section rate, postpartum hemorrhage, postpartum infection rate, neonatal Apgar score, and intrapartum complications (e.g., placental abruption, fetal distress) were compared. Results The cesarean section rate was significantly lower in the observation group (30.77%) than in the control group (100.00%),P<0.05. Compared with the control group, the observation group showed a less postpartum hemorrhage volume (P<0.05), a shorter of the total labor duration (P<0.05), and a higher neonatal Apgar score (P<0.05). There were no significant differences in amniotic fluid characteristics, postpartum infection rate, or intrapartum complications between the two groups (P>0.05). Conclusion In cases of failed induction with a water balloon and low-dose oxytocin and a cervical Bishop score <6, high artificial rupture of membranes significantly promotes labor progress, increases the rate of vaginal delivery, reduces the cesarean section rate, and demonstrates a favorable safety profile for both mother and neonate, with positive clinical significance.
