Learning Curves for Airtraq Versus King Vision Laryngoscopes

Several videolaryngoscopes have been developed but few have been compared in terms of their learning curves and efficacy. The aim of this study is to compare the learning curves of Airtraq versus King Vision in a group of residents trained in direct laryngoscopy. Four residents will perform, after a short training in manikin, 8 intubations with each device. The sequence of use of the devices will be randomized. Outcome measures will be duration of intubation attempt, glottic visualization and percentage of intubation success.
