Hemorrhagic Shock
Conditions
Brief summary
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)
Detailed description
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
Interventions
DRUGwith red blood cells (RBC), Tranexamic acid (TXA) and Fibrinogen Concentrate (FC),administration of Crystalloids and TXA.
The treating physician must have evaluated the patient's eligibility and approved the patient's enrolment in the trial prior to blood samples extraction and RBC, TXA and Fibrinogen Concentrate administration. The experimental and control arms will be determined according to the medical emergency system units with RBC, TXA and Fibrinogen Concentrate administration capacity which will be the H2 helicopter unit ,fast intervention vehicle and G409 ambulance (Advanced Life Support). The medical emergency system units are activated according current protocols based on distance, severity and weather conditions.
DRUGconventional treatment
standard treatment based on crystalloid fluid and tranexamic acid (TXA)

Intervention model description
This is a single-center, not-randomized, open-label, controlled pilot clinical trial. This study compares presence of TIC and acute traumatic hemorrhage treatment at pre-hospital phase of care with red blood cells (RBC), Tranexamic acid (TXA) and Fibrinogen Concentrate (FC) with the current treatment based on the administration of Crystalloids and TXA.
