Abstract:

Objective: To compare the completion time of endotracheal intubation and laryngeal mask implantation in operating room and on slope of ski resort, and to discuss the optimal method of estab-lishing artificial airway on slope of ski resort. Methods: The simulator was placed with the head under the feet on slope of ski resort. The artificial airway was established by tracheal intubation assisted by video laryngoscope (endotracheal intubation group) and laryngeal mask placement (laryngeal mask group) respectively by an anesthesiologist who wore full set of ski suits, helmets, goggles, gloves and ski boots. Each method was repeated 5 times, and the operation time of artificial airway establishment was recorded. While the simulated human was placed flat on the operating table in an operating room of a hospital, and the artificial airway was established by the same anesthesiologist using the same methods. Time was recorded and repeated for 5 times. The completion time of endotracheal intubation and laryngeal mask placement in the operating room and on the ski slope were compared. Results: The operating time of tracheal intubation in the operating room was longer than that of laryngeal mask placement [(79.8±10.4) s vs. (53.4±2.7) s, P=0.005], and the operating time of endotracheal intubation on the ski slope was longer than that of laryngeal mask placement [(209.2±32.7) s vs. (72.2±3.1) s, P=0.001]. The time of endotracheal intubation group on the slope of the ski resort was longer than that in the opera-ting room(t=-7.851, P=0.001). The time of laryngeal mask group on the slope was longer than that in the operating room (t=-19.391, P<0.001). Conclusion: On ski slope, both of tracheal intubation assisted by video laryngoscope and laryngeal mask placement can quickly complete the establishment of artificial airway, but the time required is longer than that in the operating room. The time of laryngeal mask placement to establish artificial airway is shorter than that of tracheal intubation assisted video laryngoscope, which may have a certain advantage in ski rescue.
