Abstract: Objective To evaluate the effectiveness and satisfaction of scenario cases based simulation teaching in the training of mechanical ventilation.Methods The scenario cases and simulation courses based on constructionism were developed in the residents.Eighty-six residents who rotated to intensive care unit from January 2016 to May 2018 were randomized to experimental group and control group.Forty-three experimental group residents were trained using scenario cases based simulation teaching,and the other forty-three control group residents were trained using traditional teaching.Theory and operation assessment were compared between two groups before and after training.Training satisfaction was also compared between two groups after rotation in the department of Critical Care Medicine.Results Total test score of post-training was significantly higher than that of pre-training in all the residents (80.5±8.3 vs 53.0±5.3,P<0.01).After training,total test score was significantly higher in the experimental group than control group (87.1± 5.8 vs 73.8± 4.1,P<0.01).Training satisfaction was also significantly higher in the experimental group than that in control group (44.5± 1.9 vs 32.9± 2.7,P<0.01).Conclusions The application of scenario cases based simulation teaching in mechanical ventilation training had achieved good results and high satisfaction.
