Abstract
Despite increasing recognition of the potential adverse effects of blood transfusion there is evidence that the procedure is over-utilized and often inappropriately and unnecessarily administered. Patient Blood Management (PBM) is a recent world-wide initiative to optimize transfusion therapy by employing preoperative and perioperative maneuvers and alternatives to avoid unnecessary blood transfusion. These approaches are, however, not restricted to the surgical setting, but may be applied whenever transfusion is contemplated. A key component of PBM is the appropriate management of anemia, a prime determinant of transfusion. Another is tolerance of anemia through the use of restrictive transfusion thresholds for transfusion and of a single unit at a time policy. Among a number of options at surgery, antifibrinolytics have proven effective at reducing blood loss and transfusion. Burgeoning literature demonstrates that PBM (also known as Blood Conservation or as ‘Bloodless Medicine/Surgery’) is costeffective while improving patient outcomes and conserving the blood supply. Data from the ONTraC program in Ontario are described herein to illustrate the effectiveness of PBM approaches
