Study Overview
Brief Summary
In this study, the investigators compare the effectiveness of two relatively new video laryngoscopes, McGrath MAC (Covidien, Dublin Ireland) and the King Vision (King Systems, Noblesville, IN), by practitioners experienced in airway management but with limited exposure to these two devices. Our hypothesis was that, the McGrath MAC device would require fewer intubation attempts and shorter intubation times than the King Vision when performed by novice users.

Arms & Interventions
King Vision Video Laryngoscope

Outcomes
Primary Outcomes
Intubation Success on First Attempt as Measured by End Tidal Carbon Dioxide
Time Frame: participants were followed up to the point the video device is removed from the airway, classified as under 90 seconds.
Secondary Outcomes
- Time to Intubation(Intubation time was initiated at the time of entry of the study device beyond the teeth/gum line and the intubation time was stopped when the study device was removed beyond the same point.)
