Abstract
Thee effect of extracorporeal ultrafiltration method(ECUM) on blood preservation and for prevention of lactic acidosis in cardiac surgery was evaluated in 94 consecutive adult patients from Jan. 1988 to Dec. 1989. Patients were deviled into 3 groups; group HC(+) (n=45): ECUM during cardiopulmonary bypass(CPB) without blood priming group HC(-) (n=25): conventional CPB without blood priming, group BL(n=24): conventional CPB with blood priming. In 70 non-blood priming cases, 48 cases (69%) did not receive transfusion through their hospital stay. and the homologous blood requirement was only 2 units per patients. Use of ECUM prevented extreme hemodilution in non-blood CPB (dilution ratio; 23.3% in group HC(+) vs 27.4% in group HC(-)), so that postoperative release of max_CK and metabolic acidosis were decreased in group HC(+).
