NEJM:氨甲环酸能预防阴道分娩后出血?

2018-08-23 xing.T MedSci原创

由此可见,接受预防性催产素治疗的阴道分娩孕妇使用氨甲环酸不会显著降低出血量超过500ml的产后出血发生率。

使用氨甲环酸可降低产后出血导致的死亡率。最近,顶级医学期刊NEJM上发表了一篇研究文章,研究人员调查了阴道分娩妇女除预防性给予催产素外预防性应用氨甲环酸是否会降低产后出血的发生率。

这是一项多中心、双盲、随机对照试验,研究人员随机分配了妊娠超过35周的计划阴道分娩单胎活胎的孕妇静脉注射1g的氨甲环酸或安慰剂,并且在分娩后预防性给予催产素。该研究的主要结果是产后出血,定义为失血量超过500ml,用收集袋进行测量。

在接受随机分组的4079名孕妇中,有3891名孕妇接受了阴道分娩。在1921名氨甲环酸组孕妇中有156名(8.1%)孕妇发生主要结局,在1918名安慰剂组孕妇中有188名(9.8%)孕妇发生主要结局(相对风险为0.83; 95%置信区间[CI]为0.68-1.01; P=0.07)。与安慰剂组相比,氨甲环酸组孕妇产后出血评估率低于安慰剂组(7.8% vs. 10.4%;相对风险为0.74; 95%CI为0.61-0.91; P=0.004; 事后调整多重比较后P=0.04),并且接受额外的子宫收缩剂频率也较低(7.2% vs. 9.7%;相对风险为0.75; 95%CI为0.61-0.92; P=0.006;校正后P=0.04)。其他次要结局在两组之间没有显著差异。氨甲环酸组和安慰剂组参与者在分娩后3个月内血栓栓塞事件的发生率之间没有显著差异(分别为0.1%和0.2%;相对风险为0.25; 95%CI为0.03-2.24)。

由此可见,接受预防性催产素治疗的阴道分娩孕妇使用氨甲环酸不会显著降低出血量超过500ml的产后出血发生率。
