ABSTRACT
To estimate the incidence, to describe the aetiology and to identify the risk factors of postpartum haemorrhage (PPH).Prospective study conducted in 106 French maternity units of six perinatal networks between December 2004 and November 2006. PPH was defined by a blood loss superior to 500 mL or necessitating an examination of the uterus, or a peripartum haemoglobin drop superior to 2 g/dL. Severe PPH was defined by at least one of these criteria : peripartum haemoglobin drop superior or equal to 4 g/dL, embolization, conservative surgical procedure, hysterectomy, transfusion, transfer to intensive care or death.The incidence of PPH was 6.4% [CI 95% 6.3-6.5] with variations between maternity units from 1.5% to 22.0%; incidence of severe PPH was 1.7% [CI 95% 1.6-1.8] with variations between units from 0% to 4%. Atony was the main aetiology of PPH, whatever the mode of delivery and severity. The risk factors identified were those classically described in the literature.In these six French perinatal networks, in 2005-2006, the PPH profile was characterized by an incidence of severe forms higher than previous population-based estimates from other countries. This suggests a more frequent aggravation of PPH and the implication of inadequate PPH management.
