E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objectve of the study is to assess the benefits of a therapeutic strategy that associates an early administration of human fibrinogen concentrate in the management of PPH on the reduction of bleeding after the initiation of prostaglandins intravenous infusion. |
L'objetif principal de l'étude est d'évaluer le bénéfice d’une stratégie thérapeutique associant une administration précoce de fibrinogène humain dans la prise en charge de l’hémorragie du post-partum sur la réduction du saignement après initiation des prostaglandines |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are:
