TI  - Laryngoscopic versus intubating LMA guided tracheal intubation by novice users--a 
      manikin study.
PG  - 412-6
AB  - AIM OF THE STUDY: Airway control is a potentially lifesaving procedure but 
      tracheal intubation by direct laryngoscopy is difficult. This pilot study was 
      conducted to determine whether tracheal intubation was more rapid and the success 
      rate higher using an intubating laryngeal mask airway. MATERIAL AND METHODS: The 
      success rates of 119 medical students without prior airway management experience 
      in ventilating and then intubating the trachea of a Laerdal Airway Management 
      Trainer with two different methods were compared. The methods were bag-mask 
      ventilation (BM-V) followed by laryngoscopic intubation (LG-TI), and intubating 
      laryngeal mask ventilation (ILMA-V) followed by ILMA-guided tracheal intubation 
      (ILMA-TI). After an introductory lecture and demonstration, each student was 
      allowed three attempts to intubate using each method in random order. RESULTS: 
      All participants were successful with BM-V and ILMA-V on the first attempt. 
      Laryngoscopic tracheal intubation was achieved by 60 (50.4%), 31 (26.1%) and 12 
      (10.1%) participants on the first, second and third attempt, respectively, while 
      16 (13.4%) failed in all three attempts. In the ILMA-TI group, 107 (90.0%), 10 
      (8.4%) and 2 (1.6%) succeeded on the first, second and third attempt, 
      respectively. None failed. The intergroup difference is highly significant 
      (p<0.001). Male participants were more successful with LG-TI than female 
      (p<0.01), but not with ILMA-TI. CONCLUSION: Laryngoscopic orotracheal intubation 
      is difficult for the untrained, but all participants were successful with 
      ILMA-TI. These data suggest that alternative devices such as the ILMA should be 
      included in the medical school curriculum for airway management.
