J Sharif Med Dent Coll Jan ;3(1):3-7.

Objective: Comparison of cold blood cardioplegia and warm blood cardioplegia in diabetic patients undergoing coronary artery bypass grafting (CABG). Methodology: This prospective comparative study included 80 diabetic patients undergoing coronary artery bypass grafting (CABG) divided into two groups. Group I included patients with cold blood cardioplegia and group II included patients on warm blood cardioplegia. Diabetic patients of both genders with normal EF were included in this study. Data was analyzed by SPSS (Statistical Package for Social Sciences) version 20.0.Ap-value <0.05 was considered significant. Results: Use of inotropic support has shown the significant difference between two groups. Results have shown that in cold cardioplegia group, 18 patients needed no inotropic support whereas in warm cardioplegia group, only 1 patient went without support. Intra-aortic balloon pump (IABP) was used in 3 patients in each group. No mortality was found in both group. Conclusion: Our study concluded that cold blood cardioplegia gives better myocardial protection than warm blood cardioplegia in diabetic patients undergoing CABG. Keywords: Cold blood cardioplegia. Warm blood cardioplegia. Cardiopulmonary bypass (CPB). Coronary artery bypass grafting (CABG).
