目的 探讨乳酸依沙吖啶联合间苯三酚静脉推注对中期妊娠引产孕妇的影响.方法 将104例中期妊娠引产孕妇采用随机数字表法分为两组,各52例.两组均给予乳酸依沙吖啶注射液羊膜腔内注射治疗,观察组联合间苯三酚静脉推注治疗.比较两组引产成功率、引产时间、胎盘胎膜残留率、疼痛程度、产后出血量、宫颈水肿及裂伤发生情况.结果 两组引产成功率及产后出血量比较差异无统计学意义(P＞0.05),观察组引产时间显著短于对照组(P＜0.01),胎盘胎膜残留率显著低于对照组(P＜0.01),疼痛程度显著低于对照组(P＜0.05),宫颈水肿及裂伤发生率均显著低于对照组(P＜0.05).结论 乳酸依沙吖啶联合间苯三酚静脉推注可显著缩短中期妊娠引产孕妇的引产时间,降低疼痛程度、胎盘胎膜残留率、宫颈水肿及裂伤发生率,值得临床推广应用.“,”Objective To investigate the effects of ethacridine lactate combined with phloroglucinol intravenous injection in pregnant woman with midtrimester induction of labor. Method 104 pregnant women with midtrimester induction of labor were randomly divided into two groups, 52 cases in each group. The two groups were all given ethacridine lactate intra-amniotic injection, and the observation group was plus phloroglucinol intravenous injection on this basis. Labor induction success rate, duration of induced abortion, residual rate of placenta and fetal membranes, pain degree, postpartum bleeding, cervical edema, laceration condition of the two groups were compared. Results The difference of labor induction success rate and postpartum bleeding between the two groups had no statistic significance (P＞0.05),duration of induced abortion in the observation group was significantly shorter than that in the control group (P ＜0.01),residual rate of placenta and fetal membranes was significantly lower than that in the control group(P＜0.01), pain degree was significantly lower than that in the control group (P＜0.05),the incidence rate of cervical edema and laceration was significantly lower than that in the control group (P＜0.05). Conclusion Ethacridine lactate combined with phloroglucinol intravenous injection can significantly shorten the duration of induced abortion of pregnant woman with midtrimester induction of labor, it can reduce pain degree,residual rate of placenta and fetal membranes, incidence rate of cervical edema and laceration, and it is worthy of clinical popularization and application.
