What is the purpose of a Massive Transfusion Protocol (MTP)?

• A. To monitor patient comfort
• B. To delay transfusion until instability worsens
• C. To evacuate blood and re-expand the lung
• D. Rapid replacement of large blood loss with balanced products (1:1:1 RBC:plasma:platelets) to prevent coagulopathy

Answer: (B)

The purpose of a massive transfusion protocol is rapid replacement of large blood loss with a balanced mix of products—typically red blood cells, plasma, and platelets in roughly a 1:1:1 ratio—to prevent coagulopathy. When a patient bleeds heavily, giving only red cells can dilute clotting factors and platelets, worsening bleeding. A balanced, rapid transfusion restores both oxygen-carrying capacity and the components needed for clot formation, helping achieve hemostasis and improve survival. The other ideas aren’t aligned with this goal: comfort monitoring isn’t the focus in massive hemorrhage, delaying transfusion worsens instability, and managing lung issues like re-expansion isn’t the purpose of the protocol.
