PARAtracheal vs CRIcoid Pressure on GLIttic DEformation (PARAGLIDE)
Sponsor: University of Liege
Summary
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.

Conditions
Interventions
Cricoid Pressure (30 N)
Manual application of posterior pressure on the cricoid cartilage at a standardized force of 30 newtons. The pressure is applied by a trained operator using one or two fingers, with the goal of compressing the esophagus against the cervical spine. The maneuver is performed after induction of general anesthesia and immediately before videolaryngoscopy. A still image of the glottic view is captured during pressure application.
Left Paratracheal Pressure (30 N)
Manual application of pressure to the left paratracheal region, lateral to the trachea and inferior to the thyroid cartilage, at a standardized force of 30 newtons. The pressure is applied by a trained operator using the thumb or fingers. The maneuver is performed after induction of general anesthesia and immediately before videolaryngoscopy. A still image of the glottic view is captured during pressure application.
