Summary

This randomized controlled trial aims to compare the first-attempt success rate of tracheal intubation through supraglottic airway devices using a conventional intubating supraglottic airway device versus a video-assisted supraglottic airway device without fiberoptic guidance in adult patients undergoing elective surgery under general anesthesia. A total of 204 participants will be randomly assigned to one of the two groups. The primary outcome is the first-attempt success rate of tracheal intubation through the supraglottic airway device. Secondary outcomes include intubation time, number of intubation attempts, overall intubation success, hemodynamic changes, airway-related complications, postoperative sore throat and hoarseness, and adverse events. The results of this study may help identify a safe and effective airway management strategy when fiberoptic bronchoscopy is unavailable.
