title: Parker Flex-It intubation stylet versus a 90-degree curved stylet during intubation with the McGrath videolaryngoscope performed by novices: a manikin study with 5 airway scenarios.
abstract: OBJECTIVE
  To compare the Parker Flex-It intubation stylet with a 90-degree curved stylet using the McGrath videolaryngoscope in 5 airway scenarios (from easy to difficult) in a manikin.
  
  
  METHODS
  Prospective, randomized study.
  
  
  METHODS
  Academic hospital.
  
  
  METHODS
  20 staff anesthesiologists with no previous experience in videolaryngoscopy.
  
  
  METHODS
  Subjects performed a total of 200 intubations with the McGrath Series 5 videolaryngoscope and completed a questionnaire afterwards.
  
  
  RESULTS
  Overall success rate was significantly higher with the Parker Flex-It intubation stylet (96 successful intubations with the Parker Flex-It vs 79 intubations in the 90° curved stylet group; P < 0.05). Intubation time was not significantly different. Subjects rated the Parker Flex-It intubation stylet as the better device for intubation with the McGrath videolaryngoscope in routine or emergency situations.
  
  
  CONCLUSIONS
  Intubation of the manikin with the McGrath videolaryngoscope had more success with the Parker Flex-It intubation stylet than a 90° curved stylet.
