目的:探讨延期妊娠引产时机对母婴结局的影响。方法:回顾性分析我院2008年6月至2012年6月住院分娩孕41～41+6周无任何合并症及并发症孕妇172例为实验组,并根据引产时间分为实验1组90例(孕41周)和实验2组82例(孕41+4周),取同期妊娠自然临产孕妇92例为观察组,分别对实验1组和实验2组、实验组和观察组孕妇的引产成功率、分娩方式、产后并发症、新生儿窒息发生情况进行回顾性分析。结果:实验1组引产成功率明显低于实验2组,剖宫产率及羊水Ⅲ度粪染率明显高于实验2组,差异均有统计学意义(P<0.05)。实验组的剖宫产率、胎儿羊水Ⅲ度粪染发生率明显高于观察组,差异有统计学意义(P<0.05);各组间产后出血量、产褥病率、急产、产时损伤、胎儿窘迫及新生儿窒息发生率比较,差异均无统计学意义(P>0.05),结论:对于无妊娠合并症及并发症的延期妊娠不需过早积极地引产,在对胎儿进行密切监护下可以等待自然临产,如41+4周仍未临产可行促宫颈成熟及引产。
Objective: To investigate the effect of postpartum induction induction labor on maternal and infant outcome. Methods: A retrospective analysis of our hospital from June 2008 to June 2012 in hospital delivery pregnancy 41 ~ 41 + 6 weeks without any complications and complications of pregnant women 172 cases for the experimental group, and according to the time of induction of labor was divided into experimental group 1 90 cases (Pregnant 41 weeks) and experimental group 2 82 cases (41 weeks pregnant + 4 weeks), taking the same period of pregnancy, 92 cases of spontaneous labor of pregnant women as the observation group, experimental group 1 and experimental group 2, experimental group and observation group pregnant women successful induction of labor Rate, mode of delivery, postpartum complications, neonatal asphyxia were retrospectively analyzed. Results: The success rate of induction of labor in experimental group 1 was significantly lower than that in experimental group 2, and the cesarean section rate and Ⅲ fecal effusion rate were significantly higher than those in experimental group 2 (P <0.05). The incidence of cesarean section in the experimental group and the fecal amniotic fluid Ⅲ degree meconium stained in the experimental group were significantly higher than those in the observation group (P <0.05); the amount of postpartum hemorrhage, puerperal morbidity, There was no significant difference in the incidence of injury, fetal distress and neonatal asphyxia between the two groups (P> 0.05). Conclusion: For pregnant women with delayed pregnancy without complications and complications of pregnancy, it is not necessary to induce labor prematurely. Monitoring can wait for natural abortion, such as 41 +4 weeks still not feasible to promote cervical ripening and induction of labor.
