Abstract

Background/aim: Recovery after coronary artery bypass graft surgery (CABG) can be complicated, leading to postoperative morbidity.The roles of hematologic and surgery-related parameters are important. The main purpose of this study is to determine the role ofpreoperative and postcardiopulmonary bypass neutrophil/lymphocyte ratio (NLR) on postoperative recovery.Materials and methods: Sixty-two patients aged between 41 and 80 years, scheduled for elective CABG surgery with ASA I-II riskand without a history of preoperative blood transfusion, were included in the study. Three patients were excluded due to their needfor additional surgical procedures other than CABG. The patients were divided into two groups that were formed depending onpreoperative NLR cut-off values below (Group 1, n = 37) and above 4 (Group 2, n = 22). Postoperative data such as length of stay in thehospital and in the intensive care unit (ICU), chest tube drainage, and incidence of atrial fibrillation were recorded for all patients.Results: Preoperative NLR was significantly lower in Group 1 (P < 0.0001), and there was no significant difference between the groups interms of postoperative NLR (P = 0.217) when the two groups were compared. The patients in Group 2 had a longer length of stay in theICU (P = 0.035) and in the hospital (P = 0.034). There was a positive correlation between preoperative NLR and length of stay in the ICU(P = 0.017) and the hospital (P = 0.014). No statistically significant differences in postoperative drainage or incidence of postoperativeatrial fibrillation were detected between the two groups.Conclusion: The results of our study demonstrate that the postoperative NLR may be useful to predict the length of hospital and ICUstays and help the management of follow-up and treatment processes in patients undergoing CABG surgery.
