On-pump Arrest Versus On-pump Beating Coronary Artery Bypass Surgery

Background: Studies that have specifically compared arrest and beating methods in on-pump coronary artery bypass grafting (CABG) are limited. Objectives: In light of the aforementioned issues, the present study aimed to compare the results of two techniques of on-pump arrest CABG and on-pump beating CABG with the same surgical and anesthesiology team and the same protocol in a single center. Methods: In this retrospective cohort study that was conducted in Ghaem Hospital of Mashhad between November 2020 and 2022, the needed data were extracted from the medical records of all patients that underwent on-pump beating CABG or on-pump arrest CABG. According to the method of operation, other variables, including post-operation bleeding, atrial and ventricular arrhythmia, returning the patient to the operating room for bleeding, need for inotrope, need for a balloon pump, hospital mortality, superficial and deep sternal infection and dehiscence, kidney injury, delayed extubation, length of hospital and intensive care unit (ICU) stay, and neurological complications were compared in the two groups. Results: A total of 105 patients with a mean age of 61.07±10.55 years were included in the study. Of these, 65 (61.9%) cases were male and the rest were female. Of the total patients included in the study, 60 subjects were in the beating group, and 45 cases were allocated to the arrest group. The postoperative outcomes were compared, and there was no significant difference between the two groups in terms of patients’ outcomes (P 0.05). Furthermore, the comparison of in-hospital and one-month mortality of patients in two groups demonstrated no significant difference between the two groups (P 0.05). Conclusion: As evidenced by the obtained results, postoperative complications, as well as in-hospital and one-month mortality, are not significantly different between on-pump arrest CABG and on-pump beating CABG.
