Transfusion

Research at the Naval Blood Research Laboratory (Boston, MA) for the past four decades has focused on the preservation of red blood cells (RBCs), platelets (PLTs), and plasma-clotting proteins to treat wounded servicemen suffering blood loss. We have studied the survival and function of fresh and preserved RBCs and PLTs and the function of fresh and frozen plasma-clotting proteins. This report summarizes our peer-reviewed publications on the effects of temperature, RBCs, PLTs, and plasma-clotting proteins on the bleeding time (BT) and nonsurgical blood loss. ⋯ The transfusion trigger for prophylactic PLT transfusion should consider both the Hct and the PLT count. The transfusion of RBCs that are both viable and functional to anemic thrombocytopenic patients may reduce the need for prophylactic leukoreduced PLTs, the alloimmunization of the patients, and the associated adverse events related to transfusion-related acute lung injury. The cost for RBC transfusions will be significantly less than the cost for the prophylactic PLT transfusions.

Continued hemorrhage remains a major cause of mortality in massively transfused patients of whom many develop coagulopathy. Reviewing transfusion practice for these patients, we found that at our hospital more than 10 percent received a suboptimal transfusion therapy and that survivors had a higher platelet count than nonsurvivors. We therefore investigated whether the blood bank could improve its service and hence improve the outcome. ⋯ The initiative from the blood bank has improved the transfusion practice and, hence, survival in massively transfused patients at our hospital.
