Blood salvage techniques and increasingly conservative physician transfusion practice in cardiac surgery have led to reports of homologous blood exposure in as few as 10% of patients having elective cardiac revascularization surgery (Ann Thorac Surg 198S;40:380). To identify current prevailing transfusion practice between centers, the authors prospectively audited 49 and 29 consecutive adult elective open-heart surgery cases (78 total) at two centers. Thirty-six of 49 patients (73%) received 245 homologous blood units (HBs) at institution 1 (m = 5.0). Fifteen of 29 (52%) received 84 HBs at institution 2 (m = 2.9,P< 0.05). Sex, age, duration of surgery, intraoperative blood salvaged, preoperative hematocrit (Hct), nadir Hct, and nadir platlet counts, and the surgeon were all found to be determinants of transfusion practice at institution 1 but not at the other. The data indicate that (1) determinants of homologous blood exposure are not consistent between institutions and instead reflect “prevailing practice” rather than need; (2) a prospective multiinstitution audit of prevailing transfusion practice in cardiac revascularization is needed to address this; (3) autologous blood pre-deposit is underused in open-heart surgery.
