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.

In the King Vision arm one patient was removed from the surgery secondary to a planned procedure change and another was removed from the study because they declined to participate after already signing consent for this study. This explains the 31 patient enrollment in the King Vision arm.
