Red cell transfusion strategies in the ICU. Transfusion Requirements in Critical Care Investigators and the Canadian Critical Care Trials Group.
Transfusion of red blood cells continues to be an important therapy for treatment of anemia in intensive care settings. The critically ill are a population predisposed to the adverse outcomes of anemia and, as such, the risks imposed on them by transfusion therapy is one of great interest. Over the past decade there has been a shift in transfusion practice with guidelines being developed that promote more conservative and safer use of blood. The Transfusion Requirements in Critical Care (TRICC) trial clearly established the safety of a restrictive transfusion strategy, suggesting that physicians could easily minimize exposure to allogeneic RBCs by lowering their transfusion threshold. Further research will add to the generalizability of this study as well as explore the possible mechanism to explain why red cell transfusions did not improve outcomes in the critically ill.
