Summary

In France in 2021, 11.6% of deliveries were complicated by a postpartum haemorrhage (PPH), including 3.0% by severe PPH (the bleeding volume exceeds 1000 ml). Severe PPH is the 5th cause of maternal death (8.4% or 1.2 deaths per 100,000 live births). These deaths were considered preventable in 90% of cases. A plasma fibrinogen concentration below 2 g/L is considered as a critical threshold which constitutes a marker of severity of PPH and is significantly associated with the occurrence of severe PPH. Measuring the concentration of fibrinogen using a rapid test, simple to perform and interpret, available in the delivery room could optimize the management of severe PPH. The qLabs®FIB analyzer distributed by the Stago Biocare laboratory for the rapid determination of the fibrinogen concentration at the patient's bedside could meet this objective.

The qLabs®FIB analyzer distributed by Stago Biocare laboratory for the rapid determination of the fibrinogen concentration at the patient's bedside could meet this objective. The hypothesis of the study is a concordance between the measurement of fibrinogen by the qLabs®FIB Monitoring system and by the Clauss fibrinogen assay in laboratory to identify patients with a fibrinogen level \< 2 g/L. The prospects are to provide an easy-to-use delocalized biology tool for early diagnosis of a fibrinogen concentration \< 2g predictive of an unfavorable evolution in the context of severe PPH.

Conditions

• Postpartum Hemorrhage

Interventions

Type	Name	Description
BIOLOGICAL	Fibrinogen concentration by the qLabs®FIB Monitoring system	A drop of blood (\~15 μL) is taken from the blood sample for the complete haemostasis assessment (prothrombin level, activated partial thromboplastin time, fibrinogen). This assessment is part of the usual management of severe postpartum haemorrhage. It is carried out urgently in the hospital's medical biology laboratory at the start of treatment (T1) and during or at the end of treatment of the haemorrhage (T2). This drop of blood will allow the measurement of the fibrinogen concentration by the qLabs®FIB Monitoring system for the study at these two times.
