Text: Simultaneous factors predictive of longer duration of third stage of labor included maternal age > or = 35 years (hazard ratio HR = 0. 990, 95 % CI 0. 981-0. 999, p = 0. 030) and duration of second stage of labor > 2 h (HR = 0. 745, 95 % CI 0. 628-0. 883, p = 0. 001) relative to second stage of labor < 1 h. Significant risk factors for PPH included chorioamnionitis (odds ratio OR = 6. 45, 95 % CI 2. 37-17. 64, p < 0. 001), nulliparity (OR = 2. 38, 95 % CI 1. 19-4. 77, p = 0. 014), overdistended uterus (OR = 2. 81, 95 % CI 1. 02-7. 76, p = 0. 047) and third stage of labor > 10 min (OR = 6. 45 95 %, CI 2. 73-22. 84, p < 0. 001 compared with third stage < or = 5 min).
