AbstractPostpartum hemorrhage is responsible for one fourth of the maternal mortality worldwide. In high resource countries there is an increasing trend in frequency of postpartum hemorrhage and need of blood transfusions. The reason for this increase is probably multifactorial. Major bleeding requires massive blood transfusion (MT), defined as transfusion of >10 units of erythrocytes within 24 hours. In Sweden the incidence of MT due to obstetric hemorrhage is reported to be 53 per 100 000 deliveries and the majority of the cases are due to placental complications, such as placenta previa and placenta accreta. These placental complications have increased over the past years as a consequence of a higher rate of cesarean deliveries. To reduce the number of deliveries requiring blood transfusion postpartum, prophylactic measures such as identification of women at increased risk, optimizing management of hemorrhage and evaluating the effect of every transfused unit of erythrocytes is important.
