胎膜早破

【摘要】胎膜早破是指在临产前胎膜自然破裂孕龄<37孕周的胎膜早破又称为早产（未足月）胎膜早破胎膜早破是围生期最常见的并发症，可以对孕产妇、胎儿和新生儿造成严重不良后果。胎膜早破可导致早产率升高，围生儿病死率增加，宫内感染率及产褥感染率均升高。

胎膜早破是指在临产前胎膜自然破裂孕龄<37孕周的胎膜早破又称为早产（未足月）胎膜早破胎膜早破是围生期最常见的并发症，可以对孕产妇、胎儿和新生儿造成严重不良后果。胎膜早破可导致早产率升高，围生儿病死率增加，宫内感染率及产褥感染率均升高。胎膜早破的原因有：创伤，宫颈内口松弛，生殖道病原微生物上行性感染，支原体感染，羊膜腔压力增高，胎儿先露部与骨盆入口衔接不好，胎膜发育不良，孕妇缺乏铜、锌微量元素。<
