Disposable one piece laryngoscopes (DOL) probably carry a lower risk of infection than conventional reusable ones. And the only one device received approval by Korean Ministry of Food and Drug safety. In the present study, we evaluated the effectiveness and usefulness of the conventional Macintosh laryngoscope (MAC) and DOL in inexperienced personnel. A randomized crossover trial was designed. Ninety seven participants (Medical, Paramedic students) were enrolled and performed endotracheal intubation with MAC and DOL in Manikin (SimMan® Laedal Medical Corporation, Stravanger; Norway). Cormack-Lehane grade, the number of attempts, time required for intubation, dental compression were measured for evaluating the effectiveness. And the participants did a questionnaire survey on the usefulness of laryngoscopes. On the aspect of effectiveness, there was a significant difference in dental compression between DOL and MAC (p=0.011). Others were no significant differences. On the aspect of usefulness, DOL was superior to MAC except in delivering power. The DOL appear to be a reasonable device in emergency airway management. It should be verified for effectiveness and usefulness of newly developed equipment in emergency airway management because it is directly related with life.
