对1000例足月产妇产后2h失血量进行测量并分析其原因。产后2h总失血量平均235.3±142.9ml。影响失血量的因素是第三产程时间、分娩方式、新生儿体重及胎盘因素。产后出血率为17.5％。对产后出血原因进行分析并提出了产后出血防治方案。

1000 term pregnancies following vaginal delivery were studies for determination and analysis of the amount of blood loss within 2 hours postpartum. The average amount of blood loss within 2 hours postpartum was 235. 3±142. 9 ml. Risk farctors leading to PPH were placenta factor, duration of third stage of labor, birth weight and way of labor. This paper is suggested that a blood loss of 400 ml within 2 hours postpartum is a more reasonable line of demarcation for the diagnosis of the postpartum hemorrage. Incidence of the postpartum hemorrage were 17. 5%. The reason of postpartum hemorrage was analysed. Finally suggestions for preventing postpartum hemorrage were made.
