Its management often relieves resuscitation that is often difficult to set up in our countries and sometimes based on invasive and mutilate surgery. Objectives: The purpose of this survey was to report frequency of this pathology, to describe its management and the factors that influence the prognosis of early postpartum hemorrhage in low setting health in Africa. Method: Authors conducted a prospective study that analyzed early postpartum hemorrhage in the motherhoods of Gabriel Touré teaching hospital and community five health reference center of the district of Bamako. It took place from January, 2015 to December, 2016. The study concerned all the cases of early postpartum hemorrhage according to WHO definition. Statistical tests used were X2 or Fisher test, its 95% confidence interval (CI95%), p value was significant if Results: Early postpartum hemorrhage frequency has been 0.7% (62 cases for 8.885 deliveries). Sixty nine and one percent (69.1%) of patients have been blood fluid transfused. Obstetric treatment dominated by uterine revision (30.7%). Hysterorraphy (4.0%), hysterectomy (3.0%), suture of uterus injuries (15.7%), hypo gastric artery ligature (2.0%) and B-Lynch compression suture (2.0%) have been the main practiced surgical operations. No satisfy blood transfusion need was 26.9%. The main risk factors of early PPH were high parity (p = 0009;RR = 3.04;CI95% [2.80 - 5.11]), prolonged labor (p = 0004;RR = 4.00;CI95% [3.06 - 10.02]), oxytocin/prostaglandin use (p = 0003;RR = 1.47;CI95% [1.17 - 3.16]). Eleven of maternal occurred (11.8%). Conclusion: Early postpartum hemorrhage is still a severe event in developing countries especially. Its management sometime consisted to invasive cares. Maternal prognosis that is influenced by unsatisfied blood need and late management is marked by high lethality.展开更多
