目的探讨不同分娩方式对产后出血的影响,并分析其发生原因。方法比较阴道产和剖宫产孕妇产后出血的发生率、出血量及出现休克和子宫全切的例数。对比两组孕妇产后出血的原因。结果阴道分娩孕妇在PPH发病率、出血量、休克发生率、子宫全切发生率上优于剖宫产孕妇,差异有统计学意义(P<0.05)。发生PPH的主要原因为宫缩乏力和胎盘因素。结论降低剖宫产率、提高阴道分娩接生技术,加强产程的观察和管理是降低产后出血发生的有效措施。
Objective To investigate the effect of different modes of delivery on postpartum hemorrhage and analyze its causes. Methods To compare the incidence of postpartum hemorrhage, vaginal delivery and cesarean section postpartum hemorrhage and cases of shock and uterine total resection. The causes of postpartum hemorrhage in two groups of pregnant women were compared. Results The vaginal delivery of pregnant women in PPH morbidity, bleeding, shock incidence, total hysterectomy rates superior to cesarean section pregnant women, the difference was statistically significant (P <0.05). The main reason for the occurrence of PPH for uterine inertia and placental factors. Conclusions It is an effective measure to reduce the incidence of postpartum hemorrhage by reducing the rate of cesarean section, improving the delivery of vaginal delivery and strengthening the observation and management of labor process.
