• 摘要：

• 目的    研究可视化技术结合以问题为基础（PBL）教学法在非麻醉专业医学生麻醉教学中的应用效果。方法    采用随机抽样法将2017年1—10月在首都医科大学三博脑科医院麻醉科实习的非麻醉专业的40名医学生分为对照组和观察组，每组20名。对照组采用传统教学法；观察组采用PBL教学法结合可视化技术进行教学。教学内容包括股神经阻滞和腰丛神经阻滞。通过出科理论与临床操作考核、座谈及满意度调查评价教学效果。结果    观察组与对照组学生的理论考核成绩差异无统计学意义［（95±4）分比（95±3）分］（P＞0.05），但观察组学生的临床操作成绩、股神经及腰丛神经阻滞一次成功率均明显高于对照组［（96±3）分比（81±5）分、90.0%（18/20）比55.0%（11/20）、75.0%（15/20）比40.0%（8/20）］，差异均有统计学意义（均P＜0.05）。结论    可视化技术结合PBL教学法能更加有效地增加非麻醉专业医学生学习麻醉相关知识及操作的兴趣和积极性，提高他们的自学能力，也进一步提高他们的临床操作水平。

• Objective    To investigate the effect of combined application of visualization technology and problem-based learning（PBL） on anesthesia teaching for non-anesthesiology students. Methods    Forty non-anesthesiology students practicing in Department of Anesthesiology of Sanbo Brain Hospital Capital Medical University from January to October 2017 were randomly divided into control group and observation group, with 20 students in each group. The control group had traditional teaching; the observation group was taught using visualization technology and PBL. Learning contents included femoral nerve block and lumbar plexus nerve block. Effects of teaching were evaluated by theoretical and clinical operational tests. Results   Score of theoretical test showed no significant difference between observation group and control group［（95±4）points vs （95±3）points］（P＞0.05）. Score of clinical operational test, first-time success rates of femoral nerve block and lumbar plexus nerve block in observation group were significantly higher than those in control group［（96±3）points vs （81±5）points, 90.0%（18/20） vs 55.0%（11/20）, 75.0%（15/20） vs 40.0%（8/20）］（P＜0.05）. Conclusion    Combination of visualization technology and PBL is effective to improve the interest and ability of non-anesthesiology students in learning theoretical knowledge and clinical operation of anaesthesia.
