Objective. To compare novice clinicians’ performance using GlideScope videolaryngoscopy (GVL) to direct laryngoscopy (DL). Methods. This was a prospective, randomized crossover study. Incoming pediatric interns intubated pediatric simulators in four normal and difficult airway scenarios with GVL and DL. Primary outcomes included time to intubation and rate of successful intubation. Interns rated their satisfaction of the devices and chose the preferred device. Results. Twenty-five interns were included. In the normal airway scenario, there were no differences in mean time for intubation with GVL or DL (61.4 versus 67.4 seconds, ) or number of successful intubations (19 versus 18, ). In the difficult airway scenario, interns took longer to intubate with GVL than DL (87.7 versus 61.3 seconds, ), but there were no differences in successful intubations (14 versus 15, ). There was a trend towards higher satisfaction for GVL than DL (7.3 versus 6.4, ), and GVL was chosen as the preferred device by a majority of interns (17/25, 68%). Conclusions. For novice clinicians, GVL does not improve time to intubation or intubation success rates in a pediatric simulator model of normal and difficult airway scenarios. Still, these novice clinicians overall preferred GVL. Introduction Successful laryngoscopy and tracheal intubation are crucial skills necessary for management of the airway in critically ill infants and children. Proficiency in these skills requires training, practice, and experience. The GlideScope videolaryngoscope (Verathon Medical, Bothell, WA, USA) has been developed to facilitate tracheal intubation, especially in difficult airway scenarios, by providing a wider angle, unobstructed view of the glottis [1–5]. The GlideScope has been shown to provide a view of the larynx that is as good as, or better than, standard direct laryngoscopy [4, 6–9] and does not require oral, pharyngeal, and tracheal axis alignment for intubation. Additionally, the GlideScope allows the trainee and the supervisor to view the same image concurrently on the video screen. Previous studies comparing GlideScope videolaryngoscopy (GVL) to direct laryngoscopy (DL) in terms of ease of use and time to intubation among experienced clinicians have reported conflicting results in both adult and pediatric populations. In pediatric studies comparing time to intubation between these devices in the operating room when used by experienced anesthesiologists, some have found that GVL required a longer time [10, 11] while others have found no difference in time to intubation between GVL and DL
