Improvement of the Glottic View by Video Laryngoscope

Status Recruiting

Clinical Trial Summary

This study aims to compare the exposure of glottis by the use of video and direct laryngoscopy.

Clinical Trial Description

It is well known that a video laryngoscope can provide better glottic view than a direct laryngoscope. However, to date, a direct laryngoscope has been the standard equipment for tracheal intubation. Recently, it seems that use of the video laryngoscope has increased. However, the advantage of the video laryngoscope over a direct laryngoscope has not been measured quantitatively. In this study, the glottic view by the use of video laryngoscope will be compared with that of the direct laryngoscope simultaneously, by using C-MAC S-imager installed with a disposable Macintosh blade. Intubating anesthesiologists will use it as if it is a direct laryngoscope. Simultaneously, the glottic views visualized on the monitor of the video laryngoscope will be recorded and evaluated later. For quantitative comparison, the glottic view will be scored with the Percentage of glottic opening scale, for both direct laryngoscopy and video laryngoscopy. Also, the glottic view will be compared by Cormack-Lehane grade. ;
