Objective: evaluate the incidence, risk factors, causes and outcomes of primary postpartum hemorrhage (PPH). Methods: A
prospective study carried out at Al Sader teaching hospital/maternity department. Data were obtained for women diagnosed with
primary PPH during the period from September 2018 to April 2019. The demographic, clinical, and outcome data were registered. Results: The study showed that the incidence of primary PPH was 1.2%. The main cause for this condition was uterine atony with rate
of 57%. The main risk factor was a multiparous woman with rate of 86%. The main method of treatment was medical not surgical
(80% vs 20%). Conclusions: Primary PPH incidence in Al Sader teaching hospital was low; the most identifiable risk factor for primary
PPH was multiparity, history of previous PPH and presence of a medical disease. The most common cause of primary PPH was
uterine atony.
