Estimates of post-partum bleeding

Post-partum bleeding was estimated during the first 72 hours in 106 women with normal delivery at term, all had live child with a body weight between 2.5 and 3.5 Kg. Three groups of women were studied: Group 1 comprised 41 volunteers with normal deliveries to whom no medication had been administered; Group 2 comprised 39 volunteers receiving 20 IU of oxytocin in 250 ml of a 5% glucose solution, immediately after delivery; and in Group 3, 26 volunteers received 0.2 mg of ergonovine maleate, orally three times daily for three days. The average post-partum blood loss in Group 1 during the first 72 hours after delivery was 151.5 ± 12.5 ml; for Group 2, 155.9 ± 13.9 ml; and for Group 3, 135.5 ± 15.9 ml. There were no significant differences among the groups and, most of the blood loss occurred during the first 24 hours after delivery.
