Objective: To analyze the impact factors of postpartum prolonged bloody lochia. Methods: 352 cases delivered in our hospital and back to the post-natal maternity clinic in 42 days after delivery from May to October in 2010 were reviewed. Age, mode of delivery, complications, and other types of relevant factors for women bloody lochia last ≥20 days were analyzed. Results: The number of cases bloody lochia ≥ 20 days was significantly more than that <20 days, the difference was statistically significant (P<0.01). The group of age≥41 years bleeding ≥20 days was significantly higher than that of the other two age groups, the cesarean section group bleeding ≥ 20 days was significantly higher than that of vaginal delivery group, exclusive breast feeding compared with other feeding methods bleeding >20 days was significantly lower than other ways of feeding, women with history of repeated abortion, puerperal infection and GDM bloody lochia prolonged significantly, the differences were statistically significant (all P<0.05). Conclusion: CDBloody lochia time postpartum showed prolonged in recent years. ②The impact of factors are related to age, cesarean section, history of repeated abortion, puerperal infection, feeding-related, and age, cesarean section, history of repeated abortion, puerperal infection are the main factors in them.%目的:分析产后血性恶露延长的影响因素.方法:选取2010年5～12月在我院分娩后42 d门诊复诊的产妇352例,对血性恶露超过20 d者进行年龄、分娩方式、合并症种类等相关因素进行分析.结果:血性恶露≥20 d例数明显多于<20 d者,差异有高度统计学意义(P<0.01),年龄≥41岁组出血≥20 d比例明显高于其他两组,剖宫产组出血≥20 d比例明显高于阴道分娩组,纯母乳喂养方式与其他喂养方式比较,出血≥20 d比例明显低于其他喂养方式,有多次人工流产史、产褥感染和妊娠期糖尿病(GDM)者均血性恶露时间延长,差异均有统计学意义(均P<0.05).结论:①近年来产后血性恶露时间均呈延长趋势.②其影响因素与年龄、剖宫产、多次人工流产史、产褥感染、喂养方式相关,其中年龄、剖宫产、多次人流史、产褥感染为主要影响因素.
