King Vision® and GlideScope® in Difficult Airways

Not Applicable

Completed

• Conditions: Airway Management
• Interventions: Device: Video laryngoscopes

• Registration Number: NCT03685968
• Lead Sponsor: The University of Texas Health Science Center, Houston

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.
