摘　　要：目的探讨中期人工流产(简称中孕引产)产后出血的危险因素。方法收集2019年1-12月该院住院引产的孕周14~28周的产妇316例,根据总出血量分为≥200 mL组(175例)和<200 mL组(141例),比较2组年龄、孕周等因素,分析产后出血量影响因素。结果中孕引产原因主要为胎儿畸形(164例)和社会因素(77例)。2组在年龄、既往妊娠次数、剖宫产次数、人工流产次数、既往胚胎停育方面比较,差异无统计学意义(P>0.05)。2组在孕周、胎盘位置、胎膜早破、胎盘粘连方面比较,差异有统计学意义(P<0.05)。孕周和胎盘粘连为中孕引产产后出血的主要高危因素(P<0.05)。结论在引产前应做好充分评估,特别是对于孕周大于20周、胎盘前置状态、胎盘粘连及胎膜早破患者,临床应做好相关准备,避免严重大出血的发生。Objective To investigate the risk factors of postpartum hemorrhage in midterm induced abortion.Methods 316 pregnant women with gestational age of 14-28 weeks who were hospitalized in the hospital from January to December in 2019 were collected and divided into≥200 mL group(175 cases)and<200 mL group(141 cases)according to the total amount of bleeding.The age,gestational age and other factors of the two groups were compared,and the influencing factors of postpartum hemorrhage were analyzed.Results The main causes of midterm induced abortion were fetal malformation(164 cases)and social factors(77 cases).There were no significant differences in age,previous pregnancy times,cesarean section times,induced abortion times and previous embryo suspension between the two groups(P>0.05).There were significant differences in gestational age,placental position,premature rupture of membranes and placental adhesion between the two groups(P<0.05).Gestational age and placental adhesions are the main risk factors of postpartum hemorrhage in midterm induced abortion(P<0.05).Conclusion Before induction of labor,full evaluation should be done.Especially for patients with gestational age more than 20 weeks,placenta previa,placenta adhesion and premature rupture of membranes,clinical preparation should be made to avoid the occurrence of severe hemorrhage.
