This prospective observational cohort study aims to evaluate the predictive value of perioperative lung ultrasound (LUS) score in determining early postoperative oxygen requirement and pulmonary complications in patients undergoing major non-thoracic surgery. Postoperative pulmonary complications remain a significant cause of morbidity and mortality in surgical patients. Lung ultrasound is a non-invasive, bedside imaging modality that allows real-time assessment of lung aeration and pathology. This study will investigate the association between perioperative LUS score and early postoperative respiratory outcomes, including oxygen requirement and pulmonary complications.
