title: [Comparison of Cormack/Lehane classification grades decided by novice residents and those by board certified anesthesiologists].
abstract: BACKGROUND
  Tracheal intubation training is one of the most important ones in anesthesia training. But it is difficult to evaluate from the outside whether the laryngeal view obtained with the laryngoscope is appropriate or not.
  
  
  METHODS
  We chose a total of 389 cases of tracheal intubation performed by 12 novice residents in 2 months, and compared the grades of Cormack/Lehane classification of the same patients decided by novice residents and board certified anesthesiologists.
  
  
  RESULTS
  During the 2-month period, the average number of tracheal intubation performed by a novice resident was 32 +/- 12 cases (mean +/- SD). A significant difference was found between Cormack/Lehane classification (P<0.05) decided by novice residents and those by board certified anesthesiologists. When the number of intubation performed by a novice resident was fewer than 30, the grade was grade II > III > I > IV. On the contrary, when it was more than 30, the ratio of grades I and II (appropriate laryngeal view) increased and the distribution changed to grade II > I >III > IV.
  
  
  CONCLUSIONS
  We considered it useful in the tracheal intubation training that certified anesthesiologists evaluate patients' Cormack/Lehane classification grades before novice residents do, because we can obtain necessary information on laryngeal view and intubation difficulty in advance.
