胎膜早破后羊水过少行宫腔注水治疗及引产的效果

Retrospective study full-term pregnancy with premature rupture of fetal membranes and oligohydramnion with induced labor by uterine cavity water injection

目的探讨足月妊娠胎膜早破致羊水过少病例行宫腔内注水及引产方法的效果。方法足月妊娠胎膜早破致羊水过少病例200例,分为宫腔注水后催产素引产者100例(注水组),随机对照组100例。两组均行催产素引产,注水组在引产前应用Foley导尿管宫腔内注入生理盐水。结果注水组自然分娩率(79%)明显高于对照组分娩率(58%);两组自然分娩病例中,对照组产程异常及不协调宫缩发生率高于注水组。结论采用宫腔注水后引产,改善宫腔环境、缓解宫腔压力及减少不协调宫缩,其利于产程进展,可提高自然分娩率。

Objective To observe the result of induced labour by uterine cavity water injection in full-term pregnancy with premature rupture of fetal membranes and oligohydramnion. Methods Select 200 cases of full-term pregnancy with premature rupture of fetal membranes and oligohydramnion, including 100 cases of induced labor by pitocin after uterine cavity water injection and 100 cases of control group without uter-ine cavity water injection. Results Two groups all conducted induced labor by pitocin; there is difference between two groups in parturition rate （P 〈0.05） ; the parturition rate of the group of induced labour by uterine cavity water injection was higher than the control group. Conclusions Induced labour by uterine cavity injection can increase parturition rate.
