The application of emergency case video segmentally introduction combining with scene simulation in cultivation of undergraduate nursing students′ skills of trauma management

目的：探讨抢救案例视频分段导入结合情景模拟在本科护生创伤急救教学中的应用效果。方法选取2013年9月至2014年4月来我院实习的护理本科生55名为对照组，采取传统的先讲解创伤处理技能知识、观看规范视频、组织护生进行小组演练的教学方法；选取2014年9月至2015年4月来我院实习的护理本科生60名为观察组，采取抢救案例视频分段导入课程讨论并讲解创伤处理技能知识，然后观看规范视频，课后进行多发伤案例情景演练。结束后比较2组护生的操作成绩及其对教学方式的评价。结果教学结束后观察组的操作成绩为（90.42±8.50）分，对照组为（84.68±8.77）分，2组比较差异有统计学意义（t=3.56，P＜0.01），观察组护生在提高学习兴趣、促进理论知识深化、提高思考和观察能力、提高分析和解决问题的能力、提高自主学习能力方面持肯定态度的百分比分别为93.33%（56/60）、91.67%（55/60）、95.00%（57/60）、100.00%（60/60）、96.67%（58/60），高于对照组的76.36%（42/55）、69.09%（38/55）、65.45%（36/55）、69.09%（38/55）、80.00%（44/55），2组比较差异有统计学意义（χ2=2.30～4.40，P＜0.05或0.01）。结论运用抢救案例视频分段导入结合情景模拟的教学法能培养本科护生创伤处理技能，提高护生运用相关知识分析和处理具体案例的能力。

Objective To investigate the effect of emergency case video segmentally introduction combining with simulation in cultivation of undergraduate nursing students′skills of trauma management. Methods A group of 55 undergraduate nursing students, recruited in the control group from September 2013 to April 2014, were instructed by traditional teaching method, the trauma management skill was delivered by lecture, video and group based practice. Another 50 undergraduate nursing students, recruited in the observation group from September 2014 to April 2015, were located in the simulation group, while the key point of trauma management was segmentally introduced by emergency case video, the skill of trauma management was delivered by lecture and video, a multiple injury case scenario was used for group practice. The score of the practice test and the evaluation of the teaching were compared among the two groups. Results The students in observation group demonstrated more skilled trauma management compared with that in the control group (90.42±8.50 vs. 84.68±8.77, t=3.56, P<0.05). The students in observation group presented significantly higher satisfaction with the teaching, improving study interesting 93.33%(56/60), promoting the theory knowledge deepen 91.67%(55/60), improving the ability of thinking and observation 95.00% (57/60/) , improving the ability of analyzing and solving problems 100.00% (60/60), enhancing the ability of independent learning 96.67%(58/60), while in the control group, they were 76.36%(42/55), 69.09%(38/55), 65.45%(36/55), 69.09%(38/55) and 80.00%(44/55), the differences between the two groups were significant (χ2 =2.30-4.40, P < 0.05). Conclusions Application of emergency case video segmentally introduction combining with simulation provided more opportunity to the undergraduate nursing students to apply relevant knowledge in analyzing and dealing with trauma cases, which contributes to the improvement of undergraduate nursing students′ skills of trauma management.
