Clinical Trial Summary

The GlideScope® videolaryngoscope usually visualize glottis better than the conventional laryngoscope. Under the visualization of glottis by GlideScope®, the insertion of endotracheal tube, however, is challenging.

The goal of this study was to determine which of two stylet (70° vs 90°) was better, as determined by time to intubation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Time to Intubation	Time from the insertion of the Glidescope blade to the measurement of end tidal CO2 (>30 mmHg)	Intraoperative intubation
Secondary	Success Rate of Intubation	The number of patients in which the intubation was successful at the first time.	Intraoperative intubation
Secondary	Difficulty of Intubation Measured Using Visual Analogue Scale	Difficulty of intubation will be measured using visual analogue scale (0:easiest, 100:most difficult).	Intraoperative intubation
Secondary	Number of Participants for Whom External Laryngeal Manipulation Was Necessary	External laryngeal manipulation is defined as the compression of neck for the facilitation of laryngeal view. Number of participants for whom external laryngeal manipulation was necessary will be measured.	Intraoperative intubation
Secondary	Cormack-Lehan Grade	The grade of Cormack-Lehan was assessed as I/II/III/IV (I: Full view of glottis, II: Partial view of glottis, III: Only epiglottis seen, none of glottis seen, IV: Neither glottis nor epiglottis seen). Grade I was considered better outcomes.	Intraoperative intubation
Secondary	Mallampati Grade	The Mallapati grade was assessed as I/II/III/IV (I: Soft palate, uvula, fauces, pillars visible, II: Soft palate, uvula, fauces visible, III: Soft palate, base of uvula visible, IV: Only hard palate visible). Grade I was considered better outcomes.	Intraoperative anesthetic induction
Secondary	Thyromental Distance	The thyromental distance was measured.	Intraoperative anesthetic induction
Secondary	Postoperative Sore Throat Measured Using Visual Analogue Scale	Postoperative sore throat will be measured using visual analogue scale (0:no pain, 100: worst pain imaginable)	at 1, 24 hr postoperatively
Secondary	Mean Blood Pressure	Mean blood pressure is measured before and 2 min after intubation.	Intraoperative intubation
Secondary	Heart Rate	Heart rates are measured before and 2 min after intubation.	Intraoperative intubation
Secondary	Airway Injury	Larynx injury is assessed.	Intraoperative intubation
