手术视频辅助Wetlab眼睑手术教学的效果评价

Assessment on the efficacy of video-assisted Wetlab eyelid surgery teaching

目的:评价手术视频辅助Wetlab眼睑手术教学的效果。方法:回顾性分析2021年4月至2021年9月在中山大学中山眼科中心住院医师规范化培训学员中使用全眼模型开展Wetlab外眼手术教学的情况。对照组(12人)采用传统教学方法,实验组(15人)在传统教学方法的基础上引入手术视频辅助教学,对学员第3、6、9次练习视频进行评分,分析教学效果。结果:2组学员的基线水平与学习曲线相似,练习第3次到第6次之间评分提高快(对照组P_(3~6)=0.001,实验组P_(3~6)<0.001),第6次到第9次之间提高速度放缓(对照组P_(6~9)=0.007,实验组P_(6~9)=0.012)。对照组学员在练习第3次用时更长[(80.3±16.1)min],随着练习次数增多,用时逐渐缩短并保持稳定(P_(3~6)=0.040,P_(6~9)=0.886,P_(3~9)=0.020),而实验组学员在练习第3次用时更短[(71.7±15.0)min],练习过程中保持稳定(P_(3~6)=0.568,P_(3~9)=0.519)。结论:手术视频辅助教学有助于学员熟悉手术操作,提高练习效率。

Objective:To assess the efficacy of video-assisted Wetlab eyelid surgery teaching.Methods:From April 2021 to September 2021,the porcine orbit model was used to conduct a Wetlab teaching course on eyelid surgeries among trainees of standardized training for residents in Zhongshan Ophthalmic Center,Sun Yat-sen University.The control group(12 trainees)used conventional teaching methods.Video-assisted teaching was offered to the test group(15 trainees)based on conventional teaching methods.The videos records of the 3rd,6th,and 9th practices were scored to analyze the teaching efficiency.Results:Trainees from the 2 groups showed a similar baseline and learning curve.Rapid improvement was found between the 3rd and 6th practice(P_(3-6)=0.001 in control group,P_(3-6)<0.001 in test group).The increment was slower between the 6th and 9th practice(P_(6-9)=0.007 from control group,P_(6-9)=0.012 from test group).Longer time was required by trainees from the control group at the 3rd practice[(80.3±16.1)min].As they practiced more,the time required gradually decreased and remained stable(P_(3-6)=0.040,P_(6-9)=0.886,P_(3-9)=0.020 from control group).Trainees from the test group spent less time at the 3rd practice[(71.7±15.0)min].The time remained stable during all practices(P_(3-6)=0.568,P_(3-9)=0.519 from test group).Conclusion:Video-assisted teaching can help trainees get familiar with surgical operations and improve the efficiency of practices.
