In this study, a newly-developed model for training veterinary students to inject the jugular vein in horses was evaluated as an additional tool to supplement the current method of teaching. The model was first validated by 19 experienced equine veterinarians, who judged the model to be a realistic and valuable tool for learning the technique. Subsequently, it was assessed using 24 students who were divided randomly into two groups. The injection technique was taught conventionally in a classroom lecture and a live demonstration to both groups, but only group 1 received additional training on the new model. All participants filled out self-assessment questionnaires before and after group 1 received training on the model. Finally, the proficiency of both groups was assessed using an objective structured clinical evaluation (OSCE) on live horses. Students from group 1 showed significantly improved confidence after their additional training on the model and also showed greater confidence when compared to group 2 students. In the OSCE, group 1 had a significantly better score compared to group 2: the median (with inter-quartile range) was 15 (0.7) vs. 11.5 (2.8) points out of 15, respectively. The training model proved to be a useful tool to teach veterinary students how to perform jugular vein injections in horses in a controlled environment, without time limitations or animal welfare concerns. The newly developed training model offers an inexpensive, efficient, animal-sparing way to teach this clinical skill to veterinary students.
在本研究中，一种新开发的用于训练兽医专业学生对马进行颈静脉注射的模型被评估为补充当前教学方法的额外工具。该模型首先由19名经验丰富的马兽医进行验证，他们认为该模型是学习该技术的现实且有价值的工具。随后，使用24名学生对其进行评估，这些学生被随机分为两组。两组均通过课堂讲授和现场演示的传统方式教授注射技术，但只有第1组接受了关于新模型的额外培训。在第1组接受模型培训前后，所有参与者都填写了自我评估问卷。最后，通过对活马进行客观结构化临床评估（OSCE）来评估两组的熟练程度。第1组学生在接受关于该模型的额外培训后，自信心显著提高，与第2组学生相比也表现出更强的自信心。在OSCE中，第1组的得分明显高于第2组：满分15分，中位数（四分位间距）分别为15（0.7）分和11.5（2.8）分。该训练模型被证明是一种有用的工具，可在可控环境中教授兽医专业学生如何对马进行颈静脉注射，且不受时间限制或动物福利问题的影响。新开发的训练模型为向兽医专业学生教授这项临床技能提供了一种廉价、高效且避免动物使用的方法。
