Which blood products are commonly used in military field resuscitation when available?

• A. Fresh whole blood only.
• B. Warmed PRBCs and plasma, used according to protocol and availability, with monitoring for transfusion reactions.
• C. Platelets exclusively.
• D. Saline solution only.

Answer: (B)

In battlefield resuscitation, the goal is to restore perfusion and support both oxygen delivery and coagulation without worsening bleeding. Warmed red blood cells provide the oxygen-carrying capacity needed to perfuse tissues, while plasma supplies coagulation factors that help control bleeding and reverse dilutional coagulopathy from fluids and transfusions. Warming the products reduces the risk of hypothermia, which can worsen coagulopathy and outcomes in trauma patients. These components are used according to established protocols and what is available, with careful monitoring for transfusion reactions such as fever, chills, allergic responses, or more serious events like hemolysis, transfusion-related acute lung injury, or fluid overload. Fresh whole blood can be used in some settings but isn’t always available, and platelets alone don’t restore oxygen delivery or provide the full coagulation activity needed in acute resuscitation, while saline alone fails to address both oxygen-carrying capacity and coagulation factors.
