血管腔内模拟器教学提升医学生的血管外科学操作技能及兴趣

摘要

目的 对医学生进行血管腔内模拟器培训,确定腔内模拟器教学是否能提升医学生的操作教学效果并提升医学生的职业兴趣.方法 对30名北京协和医学院8年制临床医学专业医学生进行血管腔内模拟器教学培训.培训前后均进行血管腔内模拟器操作考试,通过标准化量表进行量化评分,学生在培训前后使用主观量表对教学效果评分.对比培训前后的评分量表,评价腔内模拟器课程的教学效果.结果 根据评分量表,学生在培训后对疾病、操作技术的认识、处理能力及对射线及造影剂的用量等方面较培训前明显改善.学生培训后对血管外科专业的兴趣明显提升,对介入及射线的恐惧等负面态度明显降低.结论 使用血管腔内模拟器教学可以提高医学生的血管介入操作技能,使学生对血管外科工作产生职业兴趣.%Objective To determine whether endovascular simulation training in medical students may increase technical proficiency,enhance interest in vascular surgery. Methods We recruited 30 medical students from Pe-king Union Medical College prospectively. We gave these students an eight-week course with a structured curricu-lum comprised of weekly simulator sessions and theoretical lessons. A test of iliac artery balloon dilatation was con-ducted in pre-and post-course. Performance was assessed. Demographics and subjective survey data,including in-terest in vascular surgery were obtained pre-and post-course from the students too. Results Parameters measured on the standardized global endovascular rating scale,including angiography skills,wire handling and interventional criteria as well as simulator-generated metrics such as fluoroscopy time and volume of contrast used significantly im-proved from pre-to post-course values for the medical students(P<0.05) All the students agreed or strongly agreed that the simulation course increased their interest in vascular surgery. Conclusions A simulation-based endovascu-lar course improves technical performance with interest in vascular surgery training of medical students. The simula-tor is quite potential in the medical students training.
