通过对产后出血 １７９例进行回顾性分析，结果：产后出血率为１．３９％。三种分娩方式之间产后出血率比较（顺产１．１８％、剖官产１．６４％、阴道助产３．２１％）均有显著性差异。产后出血的高危因素为流产、早产、过期产、多胎妊娠、羊水过多等。输血组与无输血组发生产后出血后血红蛋白平均下降２５．６及２５．１ｇ／Ｌ（Ｐ＞０．０５），出院前血红蛋白平均下降１３．２及２０．８ｇ／Ｌ（Ｐ＜０．０５）。结论：应降低剖宫产率及阴道助产率，加强高危因素的防治。血红蛋白下降幅度与产后出血量有关，与输血无关，但输血对血红蛋白量恢复有帮助。
By retrospective analysis of 179 cases of postpartum hemorrhage, the result: postpartum hemorrhage rate was 1.39%. There was a significant difference in the rate of postpartum hemorrhage among the three modes of delivery (1.18% of births, 1.64% of census and 3.21% of vaginal deliveries). High-risk factors for postpartum hemorrhage are miscarriage, premature birth, overdue delivery, multiple pregnancies, and polyhydramnios. Hemoglobin decreased by 25.6 and 25.1 g / L on average (P> 0.05), but decreased by 13.2 and 20.8 g / L on average (P <0.05) ). Conclusion: Cesarean section rate and vaginal delivery rate should be reduced and the prevention and treatment of high risk factors should be strengthened. Hemoglobin decline with the amount of postpartum hemorrhage, has nothing to do with blood transfusion, but blood transfusion on hemoglobin recovery help.
