摘　　要：目的探讨3D打印技术在临床医学专业本科生脊柱外科学教学中的应用效果。方法选择2019年9月至11月在南华大学附属第二医院见习的2015级五年制临床医学专业50名学生为研究对象。采用随机数字表法将其分为试验组和对照组,每组25人。试验组采用3D立体模型、小组讨论式教学;对照组采用尸体标本、石膏模型教学。比较分析两组学生脊柱外科学考核成绩,采用问卷调查其对教学效果的评价。结果试验组学生课堂测验成绩[(87.06±2.74)分比(72.45±3.61)分]、期末考试成绩[(83.30±2.94)分比(75.95±3.23)分]、操作考试成绩[(85.10±2.86)分比(77.20±3.29)分]高于对照组学生,其差异均具有统计学意义(均P<0.05)。试验组学生在课堂趣味性[(7.67±1.23)分比(6.00±1.69)分]、课堂互动性[(7.53±1.35)分比(6.13±1.18)分]、学习积极性[(8.53±0.91)分比(6.87±1.06)分]、疾病认识度[(8.86±0.92)分比(7.40±1.05)分]、操作掌握度[(8.40±0.94)分比(7.00±1.03)分]、教学满意度[(9.00±0.76)分比(8.00±0.85)分]等方面明显优于对照组学生,其差异均具有统计学意义(均P<0.05)。结论 3D打印技术在临床医学专业本科生脊柱外科学教学中能够充分调动学生积极性、提高学生独立思考能力、提高教学效果,有助于学生掌握临床知识。Objective To implement and evaluate of 3D printing technology in undergraduates teaching of spinal surgery.Methods Selected fifty undergraduates of the 2015 five-year program during clerkship in our hospital from September to November 2019.They were randomly divided into two groups by the random number table,with 25 persons in each.The experimental group used 3D stereo models plus group discussion systems.The control group used traditional cadaver specimens plus plaster models.Compared and analyzed the examination results of spine surgery of the two groups students,and used questionnaires to investigate their evaluation of teaching effects.Results The scores of class test[(87.06±2.74)vs(72.45±3.61)],final examine test[(83.30±2.94)vs(75.95±3.23)]and operation test[(85.10±2.86)vs(77.20±3.29)]were higher in the experimental group than those in control group(all P<0.05).The experimental group significantly outscored the control group in learning interesting[(7.67±1.23)vs(6.00±1.69)],class interaction[(7.53±1.35)vs(6.13±1.18)],learning efficiency[(8.53±0.91)vs(6.87±1.06)]and disease awareness[(8.86±0.92)vs(7.40±1.05)],operational mastery[(8.40±0.94)vs(7.00±1.03)],teaching satisfaction[(9.00±0.76)vs(8.00±0.85)](all P<0.05).Conclusions The 3D printing technology can effectively mobilize students'enthusiasm,significantly and active thinking so improved teaching effect in undergraduate training of spine surgery,which helps students to master clinical knowledge in a solid way.
