Incidence, patterns, and factors associated with postoperative pulmonary complications in an ERAS cardiac surgery program: a 500-patient cohort study

Abstract Background Postoperative pulmonary complications (PPCs) remain the most frequent adverse events after cardiac surgery. Enhanced Recovery After Surgery (ERAS) programs aim to reduce postoperative morbidity, and data describing the incidence, patterns, and protective factors associated with PPCs within cardiac ERAS pathways remain limited. Methods We analyzed 500 consecutive adult patients undergoing cardiac surgery within a standardized ERAS program at a tertiary center. PPCs included re
