Hémorragies du post-partum non diagnostiquées : recherche fondée sur la variation du taux d'hémoglobinémie auprès de 3282 patientes

Abstract : Introduction / Objective: Post-partum haemorrhage (PPH) is defined as bleeding more than 500mL within 24 hours after the delivery. In France it concerns 5 to 10% of the delivery. .Other studies show an underestimation of blood loss. Methods: We carried an observational retrospective study in a type 3 maternity in Ile de France. Inclusion criteria were a single pregnancy, who delivered vaginally after 37 weeks gestation. Our diagnostic criteria for undiagnosed PPH (UDPPH) was a change in blood haemoglobin greater than 2g/dl. We compared characteristics of the controle's groupe and the diagnosed PPHs groupe, with the undiagnosed PPHs groupe. Results The incidence of undiagosed PPH in our population was 9.5%.Risk factors associated with UDPPH were: instrumental delivery, episiotomy, epidural anaesthesia, oxytocine, primiparity, multipara with previous cesariean and hyperthermia during labor. Conclusion: The use of systematic screening may allow an assessment of professional practices. But the usefulness of systematic prevention in long term compared to targeted prevention needs to be sought.
