A PROSPECTIVE STUDY OF PULMONARY COMPLICATIONS RELATED TO FLUID BALANCE INTRA-OPERATIVELY AND POST-OPERATIVELY 48 HOURS AFTER CABG

Introduction: Coronary artery bypass grafting (CABG) remains a cornerstone in the management of advanced coronary artery disease.Despite improvements in surgical and perioperative care, postoperative morbidity-particularly pulmonary complications and prolonged ICU stay-continues to be a concern.Perioperative fluid balance is a modifiable factor that may significantly influence these outcomes.Method: This historical cohort study included adult patients undergoing elective, isolated on-pump CABG at a tertiary cardiac center.Preoperative demographics, intraoperative variables, and postoperative fluid balance were collected.Fluid balance was calculated intra-operatively and during the first two postoperative days.Pulmonary complications and ICU length of stay were recorded.Statistical analysis was performed using appropriate univariate and multivariable methods, with significance set at p < 0.05.
