Abstract
Purpose : This research was designed to provide basic data for advanced pre-hospital airway management by comparing the time to ventilation and success rate for tracheal intubation performed with Macintosh laryngoscope and intubating Laryngeal Mask Airway(ILMA) in a manikin. Methods : All participants were novice users among EMT-Paramedic students and were divided into two groups: (1) the group for Macintosh laryngoscope guided tracheal intubation(MLG-TI) (2) the group for ILMA guided tracheal intubation(ILMA-TI). After an introductory lecture and demonstration, each group made an attempt ten tracheal intubation to compare the ventilation time and success rate for tracheal intubation. Results : 1) There was significant difference in the time to ventilation through MLG-TI, the time to first and second ventilation through ILMA-TI of the 10 attempts. 2) The time to first ventilation through ILMA-TI was significantly shorter than that of ventilation through MLG-TI. 3) There was no significant difference between the time to ventilation through MLG-TI and the time to second ventilation through ILMA-TI. 4) The success rates of ILMA-TI were significantly higher than those of MLG-TI. Conclusion : ILMA-TI can be an alternative method for MLG-TI in advanced pre-hospital airway management.
