Comparison Study of the McGrath MAC Video Laryngoscope With the King Vision

January 19, 2017 updated by: Bret Alvis, Vanderbilt University Medical Center

Randomized Controlled Trial Comparing the McGrath MAC Video Laryngoscope With the King Vision Video Laryngoscope in Adult Patients.

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
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.
participants were followed up to the point the video device is removed from the airway, classified as under 90 seconds.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to Intubation
Time Frame: 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.
Number of patients intubated in less than 90 seconds
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.
