Randomized Controlled Trial Comparative Study
Evaluation of three unchannelled videolaryngoscopes and the Macintosh laryngoscope in patients with a simulated difficult airway: a randomised, controlled trial.
This prospective randomised, controlled trial compares the performance of three unchannelled videolaryngoscopes (KingVision™ , Airtraq™ , A. P. Advance™ MAC) and the standard Macintosh laryngoscope. ⋯ P. Advance MAC and the Macintosh laryngoscope. Success rates of the unchannelled KingVision and Airtraq were similar to those of their channelled versions reported previously, indicating that performance largely depends on blade design rather than the presence of a channel for tube advancement.
