目的：寻找减轻药物流产后阴道出血的有效安全方法。方法：自愿药物流产观察组５４例、治疗组６０例，两组均采用相同的米非司酮配伍米索前列醇进行药物流产。治疗组在此基础上于服米索前列醇后始出现轻微腹痛时肌注缩宫素１０ Ｕ，每日 １次，共５天；并在服米索前列醇２４ｈ时给予云南白药２片，每日３次，共５天。观察两组流产与阴道出血情况。结果：完全流产率治疗组为９６，６７％、观察组为９２．５９％，无统计学差异；出血时间治疗组为１０．０１±５．０９天、观察组为１５．５４±８．３７，有显著性差异（Ｐ＜０．０５）；出血量治疗组明显少于观察组。结论；肌注缩宫素、口服云南白药用于药物流产，使用方便，既不增加副作用，又可减少阴道出血，不失为一种理想、简便、安全的辅助方法。
Objective: To find an effective and safe method to reduce vaginal bleeding after medical abortion.
