Abstract
This study investigates clinical evaluation of membrane oxygenators, VPCML (V) vs MASTERFLO (M). Six patients were for V group, and 7 patients for M group. There were no significant differences between the two groups in serum free hemoglobin, white blood cell counts, GOT, OPT, LDH, CPK, total bilirubin, creatinine and BUN, except platelet counts at 60min. after starting cardiopulmonary bypass. There was almost no differences in clinical use between the two membrane oxygenators.
