This is a single-center, not-randomized, open-label, controlled pilot clinical trial. This study compares presence of Trauma Induced Coagulopathy (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.
A pilot, non-randomized, open-label study of two intervention arms and controlled with the standard treatment in which 60 patients affected with acute hemorrhage due to severe trauma will enter the study with the main objective of evaluating the feasibility and the efficacy of early treatment during the pre-hospital care phase with packed red blood cells, fibrinogen concentrate and tranexamic acid (experimental arm) compared to the standard treatment based on crystalloids administration and tranexamic acid (control arm). The secondary objectives are to evaluate the safety and clinical evolution of the patients. Prior to the administration of the treatment, 2 blood samples will be extracted in both groups in order to compare the coagulation status and to be able to perform the pre-transfusion tests. On arrival at the hospital, another sample will be taken to compare changes in coagulation after the administration of the experimental or standard treatment and also between both groups. The assessment of the coagulation status will be made using the values provided by the viscoelastic test (TEG6s). The experimental and standard treatment will be administered endovenously. After treatment, patients will be evaluated up to 30 days.

Single-center, non-randomized, open-label, two-arms, controlled pilot clinical trial.
The experimental and control arms will be determined according to the SEM units with RBC, TXA and FC administration capacity (i.e. helicopter unit, rapid intervention ambulance or advanced life support ambulance). The emergency SEM units are activated according current protocols based on distance, severity and weather conditions.
