      【摘要】 目的 探讨药物流产对继后妊娠分娩期并发症的影响。方法 选择 455例有一次药物流产史的
首次分娩孕妇为实验组，560例无药物流产史的首次分娩孕妇为对照组；观察各实验对象分娩期的胎盘早剥、胎
盘粘连或植入、第三产程延长、产后出血等并发症情况。结果 实验组的第三产程和产后出血发生率高于对照
组(5.49% vs 2.14%，3.29% vs 0.71%)，胎盘早剥和胎盘粘连或植入与对照组比较差异无统计学意义（P<0.05）。
结论 药物流产可以增加继后妊娠分娩期的第三产程延长和产后出血的发生率，对胎盘早剥和胎盘粘连或植入
无影响。

【Abstract】 Objective To investigate the effect of medical abortion on the complications of subsequent preg-
nancy and parturition. Methods Four hundred and fifty-five primiparas with once medical abortion history were en-
rolled as the study group. Five hundred and sixty primiparas without medical abortion history were enrolled as the con-
trol group. Placenta abruption, placenta accretion or implantation, prolonged third stage of labor and postpartum hem-
orrhage of labor were compared between the two groups. Results The incidences of prolonged third stage of labor
and postpartum hemorrhage in the study group were significantly higher than those in the control group (5.49% vs
2.14% and 3.29% vs 0.71%). The incidence of placenta abruption, placenta accretion or implantation showed no statis-
tically significant difference between the two groups (P<0.05). Conclusion Medical abortion may enhance the occur-
rence of prolonged third stage of labor and postpartum hemorrhage, but has no effect on placenta abruption, placenta
accretion or implantation of subsequent pregnancy.
