简介:摘要目的观察米非司酮配伍依沙吖啶终止15~26周妊娠效果。方法选择100例孕15~26周要求终止妊娠者,随机分为研究组,对照组。研究组50例,口服米非司酮50mg,每12h重复1次,共服200mg,米非司酮口服完1小时后羊膜腔内注射依沙吖啶100mg。对照组按常规行依沙吖啶100mg羊膜腔内注射引产。比较两组引产成功率,宫缩开始时间,宫缩开始至胎儿胎盘娩出时间。结果研究组引产成功率,宫缩开始时间,宫缩开始至胎儿胎盘娩出时间分别为100%,(15±3.2)h,(9±1.8)h;对照组为94%,(26±7.53)h,(22±5.46)h.。结果米非司酮配伍依沙吖啶终止15~26周妊娠引产成功率,宫缩开始时间,宫缩开始至胎儿胎盘娩出时间均为统计学意义(p<0.05).结论米非司酮联合依沙吖啶引产安全,方便,能明显提高引产成功率,缩短宫缩开始时间,宫缩开始至胎儿娩出时间,减少了患者痛苦。
