Abstract
Objective: To compare early outcomes in antegrade conventional crystalloid cardioplegia with Del Nido (DN) cardioplegia in term of myocardial protection in patients undergoing CABG. Methodology: All the patients undergoing Coronary artery bypass grafting surgery were enrolled in this study after informed consent. Preoperative, intra-operative and postoperative variables were entered in the pre-designed proforma and patients were followed to compare early outcomes in Del-Nido versus Conventional Cardioplegia. Results: The mean age of the patients in Del Nido group was 54.61 ± 9.129 whereas the mean age of the patients in Conventional Cardioplegia group was 53.91 ± 10.39. There were 50(71.43%) males and 20(28.57%) females in Del-Nido group as compare with Conventional group 52(74.29%) males and 18(25.71%) females in this study. The mean cardioplegia volume given to Del Nido and Conventional Cardioplegia group as (1271.43 ± 447.91 vs 2142.86 ± 584.48 (ml/min) with p-value is <0.005 which shows there is a significant difference of Cardioplegia volume given to both groups. The mean cardiopulmonary bypass time (min) in Del Nido group was 116.87 ± 27.25 and in Conventional Cardioplegia group 106.58 ± 29.19 and the p-value of CPB time was significant 0.004. In our data 6(8.5%) patients from Del Nido Cardioplegia Group suffered from AKI whilst in Conventional Cardioplegia Group there were 7(10%) patients who suffered from AKI. Similarly 3(4.29%) patients from Del Nido Group and 2(2.86%) patients from conventional Cardioplegia Group previously suffered from stroke. Arrhythmia is a disorder of heart that affects the rate or rhythm at which the heart beats. Its p-value is significant (0.05) which shows there is a significant difference of this disorder in both groups Conclusion: There was a significant difference in post-operative complication Arrhythmia in both groups and the need for a lower cardioplegia volume and an uninterrupted procedure are the main advantages of Del Nido (DN) cardioplegia solution, which make it superior from conventional cardioplegia.
