NEJM:流产手术前需要预防性抗生素治疗吗?

2019-03-14 xing.T 网络

由此可见,与安慰剂相比,流产手术前的抗生素预防并未显著降低盆腔感染的风险。

在一些自然流产的情况下需要进行外科手术以去除保留的胚盘。抗生素预防可以降低盆腔感染的风险,这是该手术的一个重要并发症,特别是在资源匮乏的国家。

近日,顶级医学期刊NEJM上发表了一篇研究文章,研究人员进行了一项双盲、安慰剂对照的随机试验,探究了经手术完成自然流产前进行抗生素预防是否会减少资源匮乏国家妇女和青少年的盆腔感染。研究人员随机分配患者单次术前剂量为400mg口服强力霉素和400mg口服甲硝唑或相同的安慰剂。该研究主要结果是手术后14天内盆腔感染。盆腔感染的定义是四种临床特征中的两种或多种(脓性阴道分泌物、发热、子宫压痛和白细胞增多症)或这些特征之一以及临床确定的需要抗生素治疗。在揭示数据之前,盆腔感染的定义发生了变化;最初的严格定义是两个或两个以上的临床特征,不参考抗生素的使用。

研究人员在马拉维、巴基斯坦、坦桑尼亚和乌干达招募了3412名患者。共有1705名患者接受抗生素治疗,1707名患者接受安慰剂治疗。安慰剂组盆腔感染风险为4.1%(1676例妊娠中68例),安慰剂组为5.3%(1684例妊娠中90例)(风险比为0.77; 95%置信区间[CI]为0.56~1.04; P=0.09)。根据原始严格标准的盆腔感染分别被诊断为1.5%(1700例妊娠中的26例)和2.6%(1704例妊娠中的44例)(风险比为0.60; 95%CI为0.37至0.96)。不良事件之间没有显著的组间差异。

由此可见,与安慰剂相比,流产手术前的抗生素预防并未显著降低盆腔感染的风险。
