A Simulation Study of Prehospital Airway using Mannequins: A Comparison of E.T. Tube, L.M.A. Classic, S.A.L.T

Background/Objectives: This study aims to evaluate usefulness of different airway devices by comparative analyzing intubation success rate and conduct time in the ambulance while driving and in indoor using mannequins. Methods/Statistical Analysis: It was conducted by placing three mannequins to floor of desk with height of patients' bed while 1 emergency rescue professor and 1 fire fighter stand in front of 1 student who participates in assessment and 1 student who assists the assessment standing in front of each mannequin. Upon completion of first assessment, intubation practice taking place during the transfer was conducted with the use of ambulance. Findings: The result from the indoor performance demonstrates that intubation success rate except for the intubation conduct time and the total conduct time are comparable statistically. However, the result from the performance in the ambulance while driving shows a statistically significant difference in intubation success rate, the intubation conduct time, and the total conduct time. In addition, the preference survey of airway devices conducted by 60 participants of this study shows LMA-Classic is the most preferred. Application/Improvements: It was study which conducts comparative experiment only on airway devices such as three devices, it is proposed that comparative study with various airway devices and others shall be conducted.
