About this trial

This randomized crossover study evaluates the effects of left paratracheal pressure, cricoid pressure, and no pressure on glottic visualization during videolaryngoscopy in adult surgical patients. The primary endpoint is the Percentage of Glottic Opening (POGO) score assessed by blinded video review. Secondary endpoints include anatomical measures (glottic surface area, vertical and horizontal displacement of the glottic plane) and clinical outcomes (first-pass success, first-pass success without desaturation \<90%, intubation time, Intubation Difficulty Scale, hypoxemia, hemodynamic events, airway trauma, and postoperative sore throat or dysphonia). All outcomes are collected from routine anesthetic practice and video analysis, with no additional procedures.
