What ratio defines the Mass Transfusion Protocol for PRBCs, plasma, and platelets?

• A. 1:1:1 PRBCs, plasma, platelets
• B. 1:1:2 PRBCs, plasma, platelets
• C. 2:1:1 PRBCs, plasma, platelets
• D. 1:2:1 PRBCs, plasma, platelets

Answer: (A)

In massive transfusion, the aim is to replace red cells, clotting factors, and platelets in a balanced way so you don’t create or worsen coagulopathy while you control bleeding. The Mass Transfusion Protocol uses a 1:1:1 ratio of packed red blood cells to plasma to platelets. This equal pairing helps restore oxygen-carrying capacity while simultaneously supplying systemic clotting factors and platelets, effectively mimicking whole blood. Delivering blood components in this balanced way reduces dilutional coagulopathy that can occur when large amounts of red cells are given without proportional plasma and platelets. Using a ratio like 1:2:1 or 2:1:1 would tilt toward more red cells and less plasma or platelets, increasing the risk of ongoing bleeding and coagulopathy. The 1:1:1 approach is considered the most effective for stopping hemorrhage and improving survival in massive bleeding scenarios.
