目的:探讨产后出血的原因、高危因素及预防措施,降低孕妇死亡率。方法:对我院2004～2009年收治的70例产后出血病例进行回顾性分析。结果:产后出血发生率为2.77%,剖宫产发生率5.35%,阴道分娩发生率2.22%,剖宫产产后出血发生率较阴道分娩产后出血发生率高,两者比较差异有显著性。宫缩乏力是产后出血的主要原因,占68.57%,胎盘因素占18.57%,软产道裂伤占11.43%,凝血机制障碍占1.43%。相关因素为孕产史、剖宫产、产程延长等。结论:加强产前、产期保健及预防宫缩乏力,处理好各个产程、降低剖宫产率等可降低产后出血的发生率。出血发生后采取积极果断的抢救措施是防止产妇死亡的重要保证。
Objective: To explore the causes of postpartum hemorrhage, high risk factors and preventive measures to reduce maternal mortality. Methods: A retrospective analysis of 70 cases of postpartum hemorrhage admitted from 2004 to 2009 in our hospital. Results: The incidence of postpartum hemorrhage was 2.77%. The incidence of cesarean section was 5.35%. The incidence of vaginal delivery was 2.22%. The incidence of postpartum hemorrhage was higher than that of vaginal delivery after cesarean section. The difference was significant. Uterine atony was the main cause of postpartum hemorrhage, accounting for 68.57%, placental factor accounting for 18.57%, soft birth canal laceration accounted for 11.43%, coagulation disorders accounted for 1.43%. Related factors for maternal history, cesarean section, prolonged labor and so on. Conclusion: To strengthen prenatal and maternity health care and prevention of uterine atony, to deal with various labor, reduce the rate of cesarean section can reduce the incidence of postpartum hemorrhage. Take a positive and decisive rescue after the bleeding is an important guarantee to prevent maternal death.
