COMPARATIVE STUDY OF POSTOPERATIVE HEMOLYSIS USING SJM PROSTHESIS WITH DACRON AND TEFLON SEWING CUFF

Abstract

Between January, 1990 and July, 1994, 105 patients had valve replacement using SJM prosthesis. In this study, postoperative hemolysis between Dacron and Teflon sewing cuff was analyzed. They were divided into 2 groups, in group I, 53 patients had SJM prosthesis with Dacron sewing cuff, in group II, 52 patients had SJM prosthesis with Teflon sewing cuff. Parameters of hemolysis using in this study were serum LDH (IU/l), hemoglobin (Hb; g/dl), indirect bilirubin (Bil; mg/dl), serum GOT (IU/l) and serum haptoglobin (Hpt; mg/dl). They were evaluated at one month after surgery. All patients were negative in direct and indirect Coobms test, and also were free from paravalvular leakage and had no liver dysfunction. In the present study, there were no significant differences in hemolytic parameters between 2 groups, and there were no serious complications due to hemolysis in these patients.
