Bedside Assessment of Coagulation in Post-partum Hemorrhage by Thromboelastography (TEG ®6S)

Postpartum hemorrhage (PPH) is one of the leading causes of maternal deaths. Its prognosis is directly influenced by the early diagnosis and treatment of the associated coagulopathy. In this context, fibrinogen concentration is the best predictor of a severe PPH. The medical interest of thromboelastography/elastometry to early detect and guide the rapid correction of coagulopathy in PPH is regularly discussed. The principal aim of this study is to evaluate the performance of a new hemostasis point of care device (thromboelastography - TEG ®6S) for the diagnosis of coagulopathy during PPH. A secondary aim will be to determine the normal values of TEG6S at the end of a normal pregnancy.
