AB  - BACKGROUND: Several videolaryngoscopes are available which may facilitate 
      tracheal intubation in difficult airways. We compared the McGrath((R)) Series 5 and 
      the Venner A.P. Advance (APA) videolaryngoscopes with a Macintosh laryngoscope 
      by studying the performance of experienced anaesthetists using manikins in normal 
      and difficult airway scenarios. METHODS: We recruited 48 anaesthetists into a 
      randomized trial. Each performed tracheal intubation with each laryngoscope in 
      one easy and one difficult laryngoscopy scenario. The primary endpoint was time 
      to intubation. Other endpoints were time to best glottic visualization, grade of 
      view, and number of glottic advances. RESULTS: There were no dropouts. In the 
      easy scenario, the time to intubation was greater using the McGrath [median time 
      40.7 s, inter-quartile range (IQR) 31.0, 57.4, P<0.001] than the other devices. 
      In the difficult scenario, the time to intubation using the APA with Difficult 
      Airway Blade (DAB) was less (median time 23.2 s, IQR 19.8, 29.0, P<0.001) than 
      the other devices. Time to glottic visualization was reduced using the McGrath 
      and the APA with DAB. Glottic advances were fewer using the APA with DAB. 
      CONCLUSIONS: Experienced anaesthetists required a longer time for intubation in a 
      standard manikin using a McGrath compared with other laryngoscopes, but a shorter 
      time for intubation in a difficult manikin using an APA with DAB, and with fewer 
      glottic advances, compared with other laryngoscopes.
