Few guidelines exist for determining transfusion needs and strategies, namely, the appropriate use of autologous versus homologous blood for elective vascular surgery. To address this deficiency, we have developed and used an algorithm based on an analysis of the procedure, maximum surgical blood ordering schedule, patient status, and patient suitability for autologous alternatives. Data were derived from consecutive major vascular procedures done at our hospital from 1991 to 1992. The algorithm helps the surgeon assess transfusion need and patient suitability for autologous predonation and aids in selecting appropriate transfusion alternatives. Using this algorithm during the past year with 120 patients, we simplified transfusion decisions, reduced homologous blood use (to only 4.2%), and reduced wasting of autologous blood to less than 5% of the units predonated. We believe that the use of this algorithm will aid the vascular surgeon in choosing appropriate alternatives to allogeneic blood transfusion, thereby reducing the patient's exposure to risk. The algorithm should also reduce wasting of autologous blood.
