Abstract: Objective To explore the application effect of the laryngeal mask in the simulation of the airway crisis situation in the standardized training of surgical residents. Methods July 2017 to June 2018, 48 patients in the anesthesiology department of our hospital were selected to be rotated and surgically trained, and divided into test group and control group of 24 people each. Test group: training for laryngeal mask placement in a simple task trainer; control group: training in laryngeal mask placement under crisis scenario scenarios. After the training, the two groups of students were compared with the theoretical achievement, and first-aid airway treatment ability under simulated clinical crisis events, including technical ability and non-technical ability. The questionnaires were sent to the participants for feedback. Results After the training, the theoretical scores ofthe test group and control group were not statistically different (88.0±4.2 vs 86.0±3.4, P=0.076). Compared with the control group, the test group had higher success rate of laryngeal mask placement [75.0%(18/24) vs 45.83%(11/24), P=0.039], higher score of problem-solving ability (6.4±0.5 vs 2.1±1.2, P<0.01) and higher overall satisfaction of teaching (4.1±0.5 vs 3.5±0.6, P<0.01). Conclusions The application of laryngeal mask in airway crisis situation simulation could effectively improve the emergency airway management ability of surgical resident standardized training students.
