目的：探讨米非司酮联合利凡诺、米非司酮联合米索前列醇用于剖宫产术后疤痕子宫中期妊娠引产的疗效。方法：选择我院2009年1月至2013年6月收治的200例剖宫产术后疤痕子宫中期妊娠引产病例，随机分为 A 组(100例)、B 组（100例）。A 组予以米非司酮联合利凡诺引产，B 组予以米非司酮联合米索前列醇引产。比较两组引产成功率、引产时间、引产出血量、宫颈裂伤发生率以及子宫破裂等情况。结果：两组患者引产成功率、引产出血量以及宫颈裂伤发生率比较，差异均无统计学意义（P＞0.05）；A 组引产时间长于 B 组，差异有统计学意义（P＜0.05）；两组均无子宫破裂发生。结论：对于剖宫产术后疤痕子宫中孕期妊娠引产患者，米非司酮联合利凡诺、米非司酮联合米索前列醇均安全有效。
Objective: To investigate the effect of two methods on second trimester pregnancy induction with cesarean scarred uterus. Methods: 200 cases were randomly divided into 2 groups, group A(100 cases) and group B(100 cases) respectively. mifepristone and rivanol were applied to group A, and mifepristone and misoprostol were applied to group B. The differences of induction rates、induction time、blood loss volume、cervix laceration and uterus rupture in two groups were compared.Results: In two groups, the differences of induction rates、blood loss volume and cervix laceration rates were not statistical significance(P>0.05). The induction time in group A was statistical y longer than that in group B(P<0.05). There was no uterus rupture in two groups.Conclusion: The combinations of mifepristone and rivanol, mifepristone and misoprostol are both safe and effective in second trimester pregnancy induction with cesarean scarred uterus.
