米非司酮终止早孕的超声监测与分析

Clinical Study on Mifepristone and Misoprostol to End the Early Pregnancy

目的:探讨安全使用米非司酮配伍米索前列醇终止早孕的方法。方法:观察600例早孕妇女服药后孕囊排出时间、出血量及其与孕龄、孕次及孕妇年龄的关系。对服药后出血多或流产后阴道出血超过10 d者行超声检查。结果:服药4 h之内孕囊排出者占91.00%,孕龄、孕次及孕妇的年龄与孕囊排出的时间和服药后出血量无明显关系。服药6 h后孕囊未排出者,出血量明显增加,超声检查提示宫腔内有孕囊或混合性光团存在。结论:孕49 d内,药物流产成功率不会因孕龄的增加而下降,且与孕妇的年龄、孕次无关,服药6 h后未排出孕囊者,应行清宫术。
