Which transfusion pattern is designed to prevent coagulopathy during massive hemorrhage?

• A. Crystalloids
• B. Red cells and plasma only
• C. Red cells, plasma, and platelets in a balanced 1:1:1 ratio
• D. Platelets only

Answer: (C)

During massive hemorrhage, you lose not just red cells but also clotting factors and platelets. To prevent dilutional and consumptive coagulopathy, you replace all key components in a balanced way. A 1:1:1 pattern of red blood cells, plasma, and platelets provides oxygen-carrying capacity while simultaneously replenishing coagulation factors and platelet function, effectively mimicking whole blood. This helps maintain the integrity of the clotting system as bleeding is controlled. Crystalloids alone don’t restore coagulation factors or platelets and can dilute what's left; red cells with plasma misses platelets; platelets alone cannot replace red cell loss or coagulation factors. So, the balanced 1:1:1 approach is best for preventing coagulopathy during massive hemorrhage.
