Conditions
Interventions
Visual laryngoscope set:After intraoperative anesthesia induction, the epiglottis was exposed by a video laryngoscope and the supraglottis parameters were measured by a C-arm machine
Direct laryngoscopy group:After intraoperative anesthesia induction, the epiglottis was directly provoked by laryngoscopy to expose the glottis, and the supraglottic airway parameters were measured by

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The laryngoscopy exposes the distance from the root, middle and tip of the preglottis to the posterior pharyngeal wall, the distance from the uvula to the posterior pharyngeal wall, and the distance from the uvula to the tip of the epiglottis;The distance from the root, middle, and tip of the epiglottis to the posterior pharyngeal wall, the distance from the uvula to the posterior pharyngeal wall, and the distance from the uvula to the tip of the epiglottis when maximizing exposure of the glottis using laryngoscopy.;The maximum impact force, mean pressure, peak force, and distribution of multi-point pressure in pharyngeal tissue when laryngoscopy is used to maximize exposure of the glottis; | — |
Secondary
| Measure | Time frame |
|---|---|
| The classification of the patient's glottis exposure during intubation;Hemodynamic indexes (SBP, DBP, HR, mmHg) after admission, after induction, before endotracheal tube insertion, 1 min after intubation, 3 min after intubation, and 5 min after intubation;The patient was awake for 24 hours and 48 hours, with throat pain and hoarseness; | — |
