Obstet Gynecol:妊娠39周初产妇,宫颈条件不好,选择引产还是期待?

2015-11-22 Mechront 译 MedSci原创

研究者进行了一项研究,探究对宫颈条件不好的初产妇实施引产,会对剖宫产率产生什么影响。该研究纳入了≥18岁,妊娠38-38+6周的单胎初产妇,Bishop评分≤5分,将其随机分为引产组和期待组。引产组在纳入研究的1周内,39周孕以上时实施引产,对照组则期待,继续产前日常监测。初始结局指标为剖宫产发生情况。估计对照组剖宫产率为20%,引产组剖宫产率翻倍则为40%,需要162名患者。该研究纳入了2010

研究者进行了一项研究,探究对宫颈条件不好的初产妇实施引产,会对剖宫产率产生什么影响。

该研究纳入了≥18岁,妊娠38-38+6周的单胎初产妇,Bishop评分≤5分,将其随机分为引产组和期待组。引产组在纳入研究的1周内,39周孕以上时实施引产,对照组则期待,继续产前日常监测。初始结局指标为剖宫产发生情况。估计对照组剖宫产率为20%,引产组剖宫产率翻倍则为40%,需要162名患者。

该研究纳入了2010年3月-2014年2月的162名符合条件的孕妇,其中82人在引产组,80人在期待对照组。两组基线资料类似。研究数据显示,引产组剖宫产率为 30.5% (25/82),期待组该数据为17.7% (14/79),两组比较RR=1.72, 95% CI 0.96-3.06。

研究结果表明,对Bishop评分≤5分的初产妇,妊娠39周后选择引产,相比期待治疗, 会导致剖宫产率增加,但还没有到翻倍的程度。

哪些特殊情况下不得不引产

导读:哪些特殊情况“准妈妈”不得不引产?妇科专家介绍,虽然每个父母都希望看到自己的孩子健康平安地来到这个世界上,但由于某些特殊原因,为确保母体健康或使胎儿脱离宫内险境时,就必须终止妊娠,实施引产手术。 如果遇到以下几种情况就必须进行引产手术: 1、慢性肾炎患者本不宜生育,因怀孕后会增加孕妇的肾脏负担,使各种症状加重,对胎儿的生长发育和母体的健康都十分不利。所以,此类孕妇应当
