Abstract:
Preoperative blood donation is well known as one approach to reducing complications caused by homologous blood transfusion. The purpose of this study is to evaluate whether preoperative blood donation prior to coronary artery bypass grafting (CABG) reduces homologous blood transfusion. The subjects were selected from 151 consecutive patients who underwent CABG between October 1996 and October 1998. Of the 151 patients, 76 made preoperative blood donations (group A). Results in this group were compared with those obtained in the control group consisting of the subjects who received CABG without preoperative blood donation (group B, n=75). Both groups were matched for age, sex, preoperative hematocrit, cardiopulmonary bypass time, blood transfusion index (BTI; body weight×preoperative hematocrit). There were no significant differences between the two groups in terms of age and mean bypass duration. Homologous blood requirements were significantly lower in group A (78.9%) compared to group B (61.0%). BTI in group A (2, 224±447) however, was higher than that in group B (2, 129±515). In our study, preoperative blood donation was very effective to reduce homologous blood transfusion in coronary artery bypass grafting.
