2.1. Study population and processes
A total of 60 patients who underwent coronary artery bypass surgery with
on-pump CABG were included in this study. The present study was approved
by the local ethics committee (Approval number: 04.07.2022-2022/13/19).
All operations were carried out by the same operations team. Exclusion
criteria consisted of patients who had a preoperative infection, had a
blood product transfusion, received inotropic support, had a history of
oxygen support in the last two weeks, and needed postoperative
extracorporeal membrane oxygenation (ECMO) support. All procedures were
performed under general anesthesia with mild hypothermic cardiopulmonary
bypass. Intermittent isothermal blood cardioplegia was used for
myocardial protection. General anesthesia was maintained with
sevoflurane and intravenous rocuronium was used for neuromuscular
blockade.
