- Abstract
In patients with difficult airways, there can be difficulty with advancing the endotracheal tube into the airway even with a good view of the glottis using video laryngoscopy. The purpose of this study was to determine if the time required to intubate an airway and the number of gaze changes by the laryngoscopist could be decreased by using a novel video laryngoscope technique. Sixteen experienced Certified Registered Nurse Anesthetists were recruited to intubate a manikin with a normal or difficult airway using both the laryngoscope first technique and a new endotracheal tube first technique (4 intubations total) in a randomized sequence. The data were analyzed with the MannWhitney (U) test to compare the differences between the normal and difficult airway conditions. Although no significant difference was noted in the time to intubation between intubation techniques, the number of gaze changes was found to be significantly fewer in the tube first technique (P=.0009). A steep learning curve, associated with the accommodation of the manikin, was demonstrated by a decrease in time and gaze changes with subsequent intubations. Incorporating the endotracheal tube first technique into an education curriculum could increase patient safety by decreasing the time to secure a difficult airway.
