    Advice

    • Massive transfusion protocols are institution-specific, but often are 1:1:1 or 1:1:2 for fresh frozen plasma, platelets, and packed red blood cells (JAMA, 2015).
    • Remember, the ABC Score does not indicate if trauma patients should receive blood, only if they should receive blood through a massive transfusion protocol.
