Current best practices for massive transfusion emphasize a balanced resuscitation approach, generally employing a 1:1:1 ratio of packed red blood cells (PRBCs), fresh frozen plasma (FFP), and platelets. This method addresses both the oxygen-carrying deficits and the coagulation challenges that arise in patients experiencing significant hemorrhage. Ensuring an adequate supply of plasma and platelets alongside red blood cells helps prevent dilutional coagulopathy, which occurs when clotting factors become insufficient due to the rapid infusion of large volumes of red cells alone.
Evidence suggests that maintaining this balanced ratio reduces mortality, particularly in trauma cases. Including FFP and platelets alongside PRBCs restores essential clotting factors, supporting effective clot formation to help control bleeding. Anesthesia providers are essential in executing this strategy, as they continuously assess the patient's coagulation status and adjust the transfusion plan as needed. This may involve real-time modifications of the blood product ratios based on clinical evaluation and results from point-of-care tests like thromboelastography (TEG) or rotational thromboelastometry (ROTEM).
Adopting this balanced approach also helps reduce the risk of complications such as transfusion-associated circulatory overload (TACO) and transfusion-related acute lung injury (TRALI). Healthcare providers can ensure that blood product delivery is effective and efficient by applying a patient-specific, evidence-based transfusion strategy. This can ultimately improve outcomes for patients undergoing massive transfusions by catering to both their immediate needs and long-term recovery goals.
