What is the commonly used ratio in Massive Transfusion Protocol for balanced transfusion?

• A. 1:1:1 RBC:plasma:platelets
• B. 2:1:1
• C. 1:2:1
• D. 1:1:2

Answer: (A)

Massive transfusion aims to replace blood components in a way that supports coagulation early, not just oxygen delivery. Using an equal balance of red blood cells, plasma, and platelets helps restore clotting factors, fibrinogen, and platelet function at the same time as oxygen-carrying cells, reducing dilutional coagulopathy and improving overall hemostasis. This balance, typically seen as 1:1:1, mirrors whole blood and has been associated with better control of hemorrhage during massive bleeding, including improved outcomes related to bleeding in the first 24 hours in key studies. Ratios that favor RBCs over plasma or platelets (such as 2:1:1) or decrease plasma or platelets (like 1:2:1 or 1:1:2) can leave patients with insufficient coagulation components when bleeding is ongoing, increasing the risk of ongoing hemorrhage. So, prioritizing a 1:1:1 approach helps ensure blood products are available in a balanced way to support coagulation while resuscitating the patient.
