Lancet:对于不全流产的处理,助产士不逊于医师

2015-04-12 Mechront 译 MedSci原创

对于不全流产的治疗临床上通常会首选米索前列醇,但是在资源缺乏的环境中,助产士在使用该药治疗不全流产时,通常不会进行系统性的评估。因此Klingberg-Allvin M等研究者调查了助产士在诊断不全流产和使用米索前列醇治疗不全流产时的有效性和安全性,与医师对其的处理相比是否有差异。

对于不全流产的治疗临床上通常会首选米索前列醇,但是在资源缺乏的环境中,助产士在使用该药治疗不全流产时,通常不会进行系统性的评估。因此Klingberg-Allvin M等研究者调查了助产士在诊断不全流产和使用米索前列醇治疗不全流产时的有效性和安全性,与医师对其的处理相比是否有差异。

该多中心等效的随机对照试验在乌干达6个区县地区进行。纳入标准:不全流产迹象的女性。将孕早期不全流产女性随机分给医师或助产士进行临床评估和米索前列醇治疗。以治疗后14-28天内,孕妇完全流产不需要手术干预(清宫术)作为分析指标。使用普通线性混合效应模型进行PP分析(对完成治疗的人进行数据分析)。预定的等效范围为-4%~4%。

该研究共纳入2013-04-30~2014-07-21共1108名女性。其中1010名女性随机分到两组,助产士组有506人,医师组有504人。最终对955名(助产士组有472人,医师组有483人)女性进行PP分析。研究结果显示,助产士组有452名(95·8%)女性流产完全,宫内无残留物,医师组该数据为467名(96·7%)。助产士组较医师组,其基于模型的RD= -0·8% (95% CI
-2·9 to 1·4),在预定的等效范围(-4%~4%)内下降。对于整体人群,其流产不完全的比率为3·8% (36/955),两组内单独的流产不完全比率类似,助产士组为4·2%(0/472),医师组为3·3% (16/483)。研究期间,两组均为观察到严重不良反应事件。

研究结果表明,在资源缺乏的环境中,助产士在诊断不全流产和使用米索前列醇治疗不全流产时,其安全性和有效性不亚于医师对其进行的诊断和处理。在区县区域按比例增加助产士使用米索前列醇对不全流产进行治疗,可以提高流产后的安全性。
