title: Does Video Laryngoscopy Offer Advantages over Direct Laryngoscopy during Cardiopulmonary Resuscitation?
abstract: OBJECTIVE
  Interruption of chest compressions should be minimized because of its negative effects on survival. This randomized, controlled, cross-over study aimed to analyze the effectiveness of Macintosh, Miller, McCoy and McGrath laryngoscopes during with or without chest compressions in the scope of a simulated cardiopulmonary resuscitation scenario.
  
  
  METHODS
  The time required for successful tracheal intubation, number of attempts, dental trauma severity and the need for optimization manoeuvres were recorded during cardiopulmonary resuscitation with and without chest compressions. The experience with computer games during the last 10 years were asked to the participants and recorded.
  
  
  RESULTS
  McCoy laryngoscope yielded the shortest time for successful tracheal intubation both in the presence of and without chest compressions. During the use of McCoy laryngoscopes, fewer tracheal intubation attempts, lower incidence of dental trauma and lower visual analogue scale scores on the ease of intubation were recorded. Participants who are experienced computer game players using Macintosh, McCoy and McGrath achieved successful tracheal intubation in a significantly shorter time during resuscitation without chest compressions. Dental trauma incidence and number of tracheal intubation attempts did not show any significant difference between the four laryngoscopes being related to the rate of playing computer games.
  
  
  CONCLUSIONS
  McGrath video laryngoscopes do not appear to have advantages over direct laryngoscopes for securing a smooth and successful tracheal intubation during rhythmic chest compressions. We believe that as McCoy laryngoscope provided tracheal intubation in a shorter time and with fewer attempts, this laryngoscope may increase the success rate of resuscitation.
