Brief Summary:
There are several advantages of video laryngoscopy; especially their ability to provide superior glottis visualization, as compared to traditional laryngoscopy.1-3 The purpose of this three arm study was to compare the safety and efficacy of the King Vision® Video Intubation Systems (AMBU-King Systems, Denmark) to the Cobalt GlideScope® (Verathon Medical Inc., USA) in patients with anticipated difficult airways.

Arm Intervention/treatment
Experimental: Glidescope AVL Device: Video laryngoscopes
Patients were randomized into one of the three groups through a computer generated randomization schedule. Patients in group A (N= 75) will be intubated using the GlideScope® AVL, patients in group B (N= 75) will be intubated using the King Vision Channeled VL; patients in group C (N=75) will be intubated using the King Vision Video Laryngoscope with Standard (non-channeled) Blade. Patients will only be tested with one device. All patients will be intubated using a conventional ETT.
