A Comparison Between Two Video Laryngoscopes,in Successfully Intubating Pediatric Mannequins w/wo Difficult Airways

The study is a randomized crossover study where anesthesia practitioners will intubate three different pediatric infant mannequins (normal airway, anterior larynx, Pierre Robin syndrome anatomy) using three different intubation devices (the Miller blade, the Truview VL, the Glidescope Cobalt video-laryngoscope) in two different scenarios (normal neck and with an immobile neck). The order of presentation will be randomized. As this is a cross over study, all subjects will complete all scenarios. There is no placebo group, and each subject wil be his or her own control.
