ReviewPostpartum hemorrhage--update on problems of definitions and diagnosis.
Maternal mortality due to postpartum hemorrhage (PPH) continues to be one of the most important causes of maternal death worldwide. PPH is a significantly underestimated obstetric problem, primarily because a lack of definition and diagnosis. The 'traditional' definition of primary PPH based on quantification of blood loss has several limitations. ⋯ Proper and timely diagnosis of PPH should above all include accurate estimation of blood loss before vital signs change. Estimation of blood loss by calibrated bags has been shown to be significantly more accurate than visual estimation at vaginal delivery. Careful monitoring of the mother's vital signs, laboratory tests, in particular coagulation testing, and immediate diagnosis of the cause of PPH are important key factors to reduce maternal morbidity and mortality.
