新型“勇士”模拟人在战伤救治中交界区止血教学的应用

Application effect of new warrior manikin in the wound-rescuing teaching and learning course of junctional hemorrhage

目的探究不同教学手段用于本科学员交界区止血特定战伤伤情的教学效果比较与分析。方法采用随机数表法随机抽取空军军医大学2018级临床医学专业本科学员,并分为对照组和实验组,每组60人,合计120人。对照组采用传统面授、视频讲解及基础模型练习进行教学,实验组采用“勇士”战创伤模拟人系统进行教学。通过最终笔试考核成绩及操作考核评估分析组间教学效果差异,并使用教学满意度及教学效果调查问卷进行比较分析。结果实验组学员在操作规范率、操作成功率、最终考核成绩及情景应变能力多方面优于对照组,差异具有统计学意义(P<0.05);在教学满意度调查方面,实验组学员表示使用“勇士”模拟人具有更高的学习兴趣及效率,尤其是认为情景应变能力得到显著提高(P<0.01),同时绝大部分学员认为此方式的教学效果更佳。结论新型“勇士”模拟人在教学中能更好地模拟实战救治情景,特别是对于交界区止血这种伤情复杂、操作难度大、难于救治的特定伤员,能够更好地使学生掌握并提高战创伤救治综合水平,显著提升了教学效果和质量,为培养适应未来高科技局部战争的优秀卫生人员提供了有力保障。

Objective To compare and analyze the teaching effect between the application of different teaching methods used on the undergraduate students in the wound-rescuing course about junctional hemorrhage.Methods The 2018 undergraduate clinical medicine students of the Air Force Military Medical University were randomly selected by random number table method,and divided into control group and experimental groups of 60 each,for a total of 120 students.The control group adopted traditional oral teaching,video teaching and traditional mutual practice,while the experimental group adopted the new warrior manikin teaching system.The teaching effect between the two groups was analyzed through the final written test results and operational assessments,and the satisfaction and teaching effect were assessed using questionnaires.Results The undergraduates in the experimental group were better than those in the control group in terms of operational success rate,situational response,standardization rate and final assessment scores,and the difference was statistically significant differences(P<0.05).The results of the teaching satisfaction questionnaire survey results also showed that the use of the new warrior manikin improved students learning interest and learning efficiency,especially their adaptability(P<0.01),and most students thought that its teaching effect was better.Conclusion The new warrior manikin can better simulate the actual combat treatment in the classroom,especially for the specific wounded like junctional hemostasis,which are difficult to operate and complicated to treat.It can better enable military medical students to master and improve the comprehensive level of war trauma treatment,and significantly improve the effectiveness and quality of teaching.Therefore,it provides a strong guarantee for cultivating excellent health personnel to adapt to future high-tech regional wars.
