Official Title: Effects of Endotracheal Tube Cuff Pressure Management on Upper Airway Edema During Cardiopulmonary Bypass in Coronary Artery Bypass Grafting: A Double-Blind, Randomized Controlled Trial

Brief Summary: This study investigates how endotracheal tube (ETT) cuff pressure management during cardiopulmonary bypass (CPB) in coronary artery bypass grafting (CABG) affects upper airway edema.Patients will be randomized into two groups: cuff pressure kept at 0 mmHg or maintained at 20-30 mmHg during CPB.Ultrasonography will be used to measure lateral pharyngeal wall thickness, tongue parameters, and other airway dimensions at predefined perioperative time points.The primary outcome is the change in lateral pharyngeal wall…
