Tracheal intubations performed with a Macintosh laryngoscope and videolaryngoscopes on a mannequin simulating cardiac arrest.

摘要

To the Editor,In a randomized crossover trial on a mannequin simulating cardiac arrest, Shin et al. showed that tracheal intubation, during chest compressions under conditions of both normal and difficult airways, was more successful with either the Pentax-AWS~R or the GlideScope~R video-laryngoscope (97-100% success rate) than with the Macintosh laryngoscope (75-97% success rate). However, apart from the limitations described in the Discussion section of their manuscript, we note one issue in this study which may confound interpretation of the results.
