Cuff Pressure and Airway Edema in CABG With CPB

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 thickness as an indicator of airway edema. A total of 76 patients aged 18-80 years undergoing elective CABG with CPB will be enrolled. The results aim to clarify safe cuff pressure management strategies to reduce airway edema.

Airway Ultrasound As an Independent Predictor of Difficult Laryngoscopy in Patients Receiving General Anesthesia for Elective Surgery

The goal of this observational study is to determine the usefulness of pre-operative airway ultrasound in predicting difficult laryngoscopy in patients receiving general anesthesia for elective surgery. The main question it aims to answer is the independent prognostic value of pre-operative airway ultrasound.

The USE of ULTRASONOGRAPHY in CONFIRMING SUPRAGLOTTIC AIRWAY DEVICE PLACEMENT in PEDIATRIC PATIENTS

In this study,the investigators evaluated the placement of the supraglottic airway device with ultrasonographic imaging.
