Comparison Of Post Operative Length Of Stay And Mortality On-Pump And Off-Pump Coronary-Artery Bypass Grafting In The Cardiac Icu Of Haji Adam Malik Hospital Medan

Introduction: Coronary-Artery Bypass Grafting (CABG) is currently a heart bypass surgery procedure that is often performed and with developing technology. The most common CABG techniques are on-pump and off-pump. This difference in surgical technique affects the final postoperative outcome, namely the length of stay and mortality of patients in the cardiac ICU. On-pump CABG performed at cardiopulmonary bypass is one of the most commonly performed procedures and an excellent treatment for ischemic heart disease. However, the results of a recent retrospective study found that length of stay and postoperative mortality can be reduced when coronary artery bypass surgery is performed using the off-pump technique. Purpose: This study aims to compare the length of stay and mortality of postoperative on-pump and off-pump CABG patients in the cardiac ICU of Haji Adam Malik General Hospital, Medan. Methods: This study is an analytic study with a retrospective research method with secondary data sources obtained from cardiac ICU medical records for the period January 2016 – December 2021. Samples were on-pump and off-pump CABG postoperative patients undergoing treatment in the cardiac ICU who met the inclusion and exclusion criteria were collected by total sampling method. Results: It was found that the ICU stay after on-pump surgery was significantly longer than off-pump, with the median value for ICU stay in the on-pump surgical technique was 2 days while in the off-pump it was 1 day (Mean = 2.335; SE = 0.103 vs. Mean = 1.709; SE = 0.140) with p<0.05. There was no significant difference between on-pump and off-pump CABG postoperative mortality with p>0.05. Conclusion: The length of stay in the ICU after on-pump surgery is longer than off-pump. There was no difference in postoperative mortality between on-pump and off-pump CABG.
