目的 :为了解米非司酮配伍米索前列醇终止中期妊娠的效果。方法 :将 12 3例中期妊娠( 10～ 2 7周 )健康妇女随机分成两组 ,A组给予米非司酮配伍米索前列醇引产 ;B组给予利凡诺引产。结果 :两组年龄、孕次、产次、孕周相比较 ,差异均无显著性意义 (P >0 .0 5) ,说明有可比性。两组完全流产率和引产时出血量差异有极显著意义 (P <0 .0 1) ,A组引产效果优于B组 Objective: To understand the effect of mifepristone and misoprostol to terminate mid-term pregnancy. Methods: A total of 123 healthy pregnant women (10 ~ 27 weeks) were randomly divided into two groups. Group A was given mifepristone with misoprostol, and group B was given rivanol. Results: There was no significant difference between the two groups in age, gestational age, parity and gestational age (P> 0.05), indicating comparability. There was significant difference between the two groups in the rate of complete abortion and the amount of bleeding induced by labor (P <0.01). The effect of induction of labor in group A was better than that in group B
