Description

<p> Abstract Simulation using an airway simulator has been a useful tool for training and education for airway management. Since there are various types of airway management simulator, it is necessary to understand the characteristics of each simulator to enhance educational effectiveness. The purpose of this study was to examine the time required for intubation using four types of airway simulator and the characteristics of each.</p><p> Five dental anesthesiologists performed oral intubation three times each with a direct laryngoscope (DL) or video laryngoscope (VL) using four types of airway simulator (A-D) and the time required for intubation was measured. The results were expressed as mean±standard deviation. Parametric data were analyzed with one-way repeated measures analysis of variance or the t-test. A value of P<0.05 was considered statistically significant. We also investigated the Cormack-Lehane (C-L) classification in intubating and the characteristics of each simulator.</p><p> The intubation time using each simulator was as follows : A : 11.04±2.22 ; B : 11.52±2.15 ; C : 13.80±2.68 ; D : 13.84±2.40 seconds with a DL, and A : 7.98±2.52 ; B : 8.24±2.00 ; D : 8.58±2.19 ; C : 12.74±4.15 seconds with a VL (p>0.05). A significantly shorter time was required for intubation using simulator D with the VL than the DL (p=0.01). The reason for this may be that simulator D has an anatomical characteristic similar to the biological index. All records of C-L classifications with a DL or VL using each type of simulator were C-L Ⅰ.</p><p> It is suggested that simulators A and B may be easier for a student or resident to intubate than C and D. Since the time required for tracheal intubation using simulator D by a VL was significantly shorter than that by a DL, it is considered that simulator D may be anatomically similar to the human body.</p>
