Effect of Modified Stylet Angulation on the Intubation With GlideScope®
- Conditions
- CholecystitisStomach Cancer
- Interventions
- Procedure: Glidescope guided intubationDevice: GlideScope®
- Registration Number
- NCT02547064
- Lead Sponsor
- Keimyung University Dongsan Medical Center
- Brief 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.

Group Intervention Description 70 degree Glidescope guided intubation The ETT was bent by 70° at a point 6 cm from its distal end and the proximal portion of the ETT was formed as the shape of the GL blade until the point of the handle. 90 degree GlideScope® The ETT with the 90° angle stylet was bent at a point 8 cm from its distal end. 70 degree GlideScope® The ETT was bent by 70° at a point 6 cm from its distal end and the proximal portion of the ETT was formed as the shape of the GL blade until the point of the handle. 90 degree Glidescope guided intubation The ETT with the 90° angle stylet was bent at a point 8 cm from its distal end.
- Primary Outcome Measures
Name Time Method Time to Intubation Intraoperative intubation Time from the insertion of the Glidescope blade to the measurement of end tidal CO2 (\>30 mmHg)
- Secondary Outcome Measures
Name Time Method Difficulty of Intubation Measured Using Visual Analogue Scale Intraoperative intubation Difficulty of intubation will be measured using visual analogue scale (0:easiest, 100:most difficult).
Thyromental Distance Intraoperative anesthetic induction The thyromental distance was measured.
Postoperative Sore Throat Measured Using Visual Analogue Scale at 1, 24 hr postoperatively Postoperative sore throat will be measured using visual analogue scale (0:no pain, 100: worst pain imaginable)
Heart Rate Intraoperative intubation Heart rates are measured before and 2 min after intubation.
Number of Participants for Whom External Laryngeal Manipulation Was Necessary Intraoperative intubation 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.
Mallampati Grade Intraoperative anesthetic induction 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.
Mean Blood Pressure Intraoperative intubation Mean blood pressure is measured before and 2 min after intubation.
Success Rate of Intubation Intraoperative intubation The number of patients in which the intubation was successful at the first time.
Cormack-Lehan Grade Intraoperative intubation 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.
Airway Injury Intraoperative intubation Larynx injury is assessed.
