Comparative Outcomes of Prothrombin Complex Concentrate and Recombinant Activated Factor VIIa in Trauma-Associated Massive Transfusion: A Retrospective Cohort Study
This study aims to compare the incidence of thromboembolic complications among trauma patients receiving PCC, rFVIIa, both agents, or neither during massive transfusion. Secondary objectives include comparing mortality, transfusion requirements, intensive care unit (ICU) and hospital length of stay, ventilator-free days, and the incidence of transfusion-associated adverse events such as transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO). Subgroup analyses will evaluate outcomes in patients with and without laboratory-confirmed TIC (INR \>1.2).
• Adults ≥18 years
• Trauma patients directly admitted from the scene with highest-level trauma activation: Injury -Severity Score (ISS) \>15.
• Requirement for massive transfusion, defined as ≥3 units packed red blood cells (PRBC) within the first hour or ≥10 PRBC within the first 24 hours
