Obstet Gynecol:催产素联合米索前列醇能减少产后出血吗?

2016-09-26 MedSci MedSci原创

由此可见,米索前列醇联合预防性常规催产素使用并没有降低产后出血风险率,反而提高了产妇不良事件的发生率。

近日,妇产科领域权威杂志《obstetrics and gynecology》发表了旨在评价米索前列醇与催产素联合应用用于预防产后出血有效性和安全性的文章。

这是一项多中心、双盲、随机、安慰剂对照试验,研究招募在第一产程预期可经阴道分娩,孕周在36 - 42周的妇女,排除标准为多胎妊娠、对米索前列醇过度敏感和行剖宫产术的孕妇。参与者接受常规静脉注射催产素,分娩出新生儿后经随机分配立即口服400mg米索前列醇或安慰剂。主要指标是产后出血(500ml或更多,在出生2小时内),次要指标包括严重的产后出血(1000 ml或更多)和不良的产妇事件,如发烧、颤抖、恶心。


参与者招募时间是从2010年4月至2013年9月,两组基线特征相似。由于中期分析显示米索前列醇是无效的并与明显的不良效应有关,这项研究共纳入了1721例研究对象后就被终止。在米索前列醇组的产后出血率为8.4%(68/806),安慰剂组为8.3%(66/797),重度产后出血发生率分别为1.8%和2.4%(P =0.57)。产妇的不良事件在米索前列醇组更频繁地发生(米索前列醇组发热30.4%,安慰剂组为6.3%,P <0.001;米索前列醇组颤抖占10.8%,安慰剂组为0.6%,P<0.001)。

由此可见,米索前列醇联合预防性常规催产素使用并没有降低产后出血风险率,反而提高了产妇不良事件的发生率。
