title: Comparison of the Airtraq and McCoy laryngoscopes using a rigid neck collar in patients with simulated difficult laryngoscopy.
abstract: OBJECTIVE
  To determine the efficacy of the Airtraq versus the McCoy laryngoscope as intubation devices with the neck stabilized by a rigid cervical collar.
  
  
  METHODS
  Prospective, randomized, double-blinded study.
  
  
  METHODS
  Jawaharlal Nehru Medical College.
  
  
  METHODS
  60 ASA physical status 1, 2, and 3 patients, aged 18-70 years, scheduled for various surgical procedures requiring tracheal intubation for surgical anesthesia.
  
  
  METHODS
  Patients were randomly allocated to undergo intubation with the McCoy (n = 30) or Airtraq (n = 30) laryngoscope.
  
  
  RESULTS
  Differences in intubation times between the Airtraq and the McCoy laryngoscope, modified Cormack-Lehane score, percentage of glottic opening (POGO) score, and airway trauma were compared. Overall intubation success rates were 100% with both devices and a similar number of intubation attempts were required. However, the mean (SD) time required for successful intubation was shorter with the Airtraq (28.73 ± 6.39 sec) than the McCoy laryngoscope (39.11 ± 14.01 sec; P < 0.0001). The frequencies of intubation complications were similar. Esophageal intubation occurred in 4 cases but only with the McCoy laryngoscope.
  
  
  CONCLUSIONS
  Intubation time was shorter with the Airtraq than the McCoy laryngoscope, even though the overall success rates between the two devices were similar.
