Transfusion of Red Blood Cells, Tranexamic Acid and Fibrinogen Concentrate for Severe Trauma Hemorrhage

Transfusion of Red Blood Cells, Tranexamic Acid and Fibrinogen Concentrate for Severe Trauma Hemorrhage at Pre-hospital Phase of Care. a Pilot Trial

Study Design: Single-center, not-randomized, open-label, two-arms controlled pilot clinical trial.

Health Condition: Patients with severe trauma with a need for transfusion and categorized as priority 0 or 1 according to the Catalan Health Service (CatSalut) Polytrauma Code (PPT)

Major hemorrhage in the setting of severe trauma patient is associated with significant morbidity and mortality. Hemorrhage is compounded by trauma induced coagulopathy of which hypo/dysfibrinogenemia and hypoperfusion play a significant role. There is a good evidence to suggest that hypofibrinogenemia in trauma is associated with worse outcomes and it is postulated that early replacement of fibrinogen and red blood cells packages may reduce hemorrhage and improve outcomes even in the pre-hospital phase of care. In this pilot study, the investigators will try to prove the feasibility and efficacy of managing the severe traumatic patient with red blood cells transfusion, tranexamic acid (TXA) and fibrinogen concentrate compared to standard treatment based on crystalloid fluid and TXA in the pre-hospital phase of care.

Early administration at pre-hospital phase of care of RBC, FC and TXA is feasible , secure and can help controlling trauma induced coagulopathy. Better outcomes in terms of mortality, less transfusion requirements and less crystalloid administration is expected
