Use of a tracheal tube introducer guide to facilitate difficult intubation with a video laryngoscope

摘要

Anterior larynx is a common anatomical feature resulting in difficult laryngoscopy. Despite the use of video laryngoscopes to produce a good laryngoscopic view, intubation difficulties and failures have been reported. The use of a tracheal tube introducer (TTI) (i.e., "bougie") has been advocated as an adjunct in this clinical scenario.Nevertheless, TTI insertion may be impeded by the acute angle it must traverse through the oropharynx into the trachea.Herein, we present a novel approach that can be used to guide a TTI past the vocal cords when using a video laryngoscope in a difficult intubation scenario.
