随着现代社会的高速发展,对于便捷、快速的需求越来越高,随之出现的高冲击力外伤也越来越重,其中以骨盆骨折最明显.相对较高的死亡率主要源于静脉和动脉的相关损伤与破坏断裂结构附近的血管 [1].盆腔填塞和外固定支架对于静脉或骨髓腔等低压出血有一定效果,而对于动脉性的高压出血效果不佳.盆腔血管栓塞术是一种有效治疗盆腔出血的方法 [2].
Objective:To evaluate the effect of immersive virtual reality(IVR) combined with high simulation makeup technology in the training of emergency medical rescue in disaster scene.Methods:From April 2021 to December 2021, a total of 97 undergraduates from five-year program of clinical medicine enrolled in 2018 in Jiaxing University College of Medicine received the training of emergency medical rescue in disaster scene .They were divided into traditional teaching group (49 students) and IVR teaching group (48 students). PBL method was adopted in the traditional teaching group and IVR combined with high simulation makeup technology was adopted in the IVR teaching group .By the end of the course, the teaching effect has been evaluated by the final exam results of the two groups and the questionnaire survey of the IVR teaching group. The final results between the two groups were compared using the t-test or the chi-square test. Results:The questionnaire survey in IVR teaching group showed that 93.6% (44/47) students recognized the teaching method of IVR combined with high simulation makeup technology which provided a good environmental experience in disaster scene, 83.0% (39/47) students believed that this teaching method had a good sensory experience and 83.0% (39/47) of them experienced encouragement to their active learning. The average exam score related to emergency medical rescue in IVR teaching group were significantly higher than that in the traditional teaching group [(9.10±2.36) vs. (7.11±1.65), P<0.001]. Conclusions:IVR combined with high simulation makeup technology can improve students' environmental experience and sensory experience in the training of emergency medical rescue in disaster scene, which meet the needs from students and thus improve the quality of teaching.
