[Analysis of risk factors of postpartum hemorrhage in rural women].
Sixty variables during pregnancy, labor and delivery of 951 rural women were analyzed to identify the risk factors of postpartum hemorrhage. The result showed that uterine atony (RR = 13.30, 95% CI = 8.23-21.50) and its related factors were the major risk factors of postpartum hemorrhage. The related factors included prolonged labor (3.49, 1.98-6.15), prolonged second stage of labor (2.72, 1.54-4.78), pregnancy induced hypertension (mild 2.35, 1.11-4.99; > or = moderate 3.04, 1.38-6.70), neonatal weight > or = 3.500 g (2.55, 1.66-3.91). Another category of postpartum hemorrhage risk factors were placental factors (6.32, 2.35-17.01), the third stage of labor > or = 10 minutes (2.65, 1.74-4.01), parity > or = 2 (2.61, 1.69-4.01) and maternal age > or = 30 (2.19, 1.13-4.24). The authors recommends that the stress should be put on the management of labor and delivery, to prevent and management of postpartum hemorrhage, through training the birth attendants to promote their ability to prevent and manage uterine atony and correct management of labor and delivery.
