If you accept vs. refuse

Accept Why some people accept
  • Preserves all blood components in their natural ratio
  • May be the only option in massive hemorrhage when component therapy is unavailable
  • Used in some military and remote settings where component separation isn't feasible
Refuse Why some people refuse
  • Contains all components including white cells, increasing risk of transfusion reactions
  • Higher risk of TRALI (transfusion-related acute lung injury) compared to components
  • Some faith traditions consider whole blood to be equivalent to the blood referenced in religious texts

Alternatives

Pharmaceutical Volume Expanders Non-blood IV fluids (saline, Ringer's lactate, dextran, hetastarch) used to maintain blood volume without transfusion.
