目的 探讨孕中期合并胎盘前置状态患者采用利凡诺引产的临床效果.方法 选取我院2010年1月至2015年12月孕中期合并胎盘前置状态进行利凡诺引产患者16例作为观察组,同期胎盘位置正常引产患者22例作为对照组,比较2组患者产程时间、产后24 h出血量、一次引产成功率、大出血需剖宫取胎及术后感染等探讨利凡诺引产的临床效果.结果 观察组患者的引产成功率、产程时间、大出血需剖宫取胎与对照组比较,差异无统计学意义(P>0.05);产时及产后出血量多于对照组,差异有统计学意义(P<0.05),但小于500 mL,未明显增加患者相关风险.结论 孕中期胎盘前置状态行利凡诺引产安全、有效,副作用少、创伤小,是孕中期胎盘前置状态患者首选的引产方法.%Objective To investigate the effect of rivanol induction on pregnancy termination for patients with placenta previa during midtrimester.Methods From January 2010 to December 2015,16 patients of placenta previa underwent pregnancy termination induced by rivanol during midtrimester were regarded as the observation group, and 22 patients with normal placental position were regarded as the control group.The delivery time,amount of postpartum hemorrhage within 24 hours,one-time success rate of induced abortion,caesarean due to massive haemorrhage and postoperative infection of the two groups were recorded to analyze the clinical effect of rivanol.Results There was no statistically significant differences in the success rate,delivery time and caesarean due to massive haemorrhage between the two groups(P>0.05).The amount of intrapartum and postpartum hemorrhage in the observation group was more than that of the control group,with a statistically significant difference(P<0.05),but it was less than 500 mL,which did not significantly increase the related risk for patients.Conclusion Induced abortion by rivanol is a simple,safe and effective method for patients with placenta previa during midtrimester with fewer side effects and less trauma,which is the preferred method for such patients.
