title: [Comparative study of the KingVision videolaryngoscope and Airwayscope using manikins].
abstract: BACKGROUND
  KingVision (KV) is a new videolaryngoscope. In this study, we compared the ease of use of the KV with the Airwayscope (AWS) by experienced personnel in a simulated manikin.
  
  
  METHODS
  Twenty-eight anesthesiologists participated in this study. We used an advanced patient simulator (AIRSIM) to simulate normal manikin and difficult airway scenarios including cervical spine rigidity and limited mouth opening. We compared the time required for visualization of the glottis (Tv) and tracheal intubation (Ti), and analyzed the percentage of glottic opening (POGO) score and the success rates for tracheal intubation.
  
  
  RESULTS
  In normal manikin, the Tv and Ti with the KV were significantly shorter than with the AWS (P < 0.05). The POGO score with the KV was higher than with the AWS (P < 0.05). In difficult airway scenarios including both cervical spine rigidity and limited mouth opening, the Tv and Ti with the KV were shorter than with only the AWS (P < 0.05). There is not much difference between KV and AWS regarding the POGO score in difficult airway.
  
  
  CONCLUSIONS
  KV may be a suitable device for routine anesthesia care and difficult airway intubation. Further studies in a clinical setting are necessary to confirm these findings.
