新型皮肤手术模具在住院医师规范化培训中的应用

Application of a new type of dermatologic surgical mold in standardized residency training

目的探讨基于3D打印的新型仿真皮肤手术模具在皮肤科住院医师规范化培训中的应用效果。方法将2018年1月至2019年5月在广州医科大学附属第二医院皮肤科的35名规培生进行分组,分为基于3D打印的新型模具组(n=18)和传统模具组(n=17)。对两组规培生在模具上进行皮肤活检术考核,并对教学效果实施问卷调查评价。数据分析采用SPSS 22.0统计软件。计量数据用(均数±标准差)表示,新型模具组及传统模具组组间比较采用两独立样本t检验。结果新型模具组的规培生在皮肤活检术考核的成绩高于传统模具组,差异有统计学意义(P<0.01);在教学效果调查问卷的各项评分均优于传统模具组,差异有统计学意义(P<0.01)。结论基于3D打印的新型仿真皮肤手术模具,让规培生的操作技能得到很好的训练,为实际临床操作奠定了坚实的基础,教学效果显著提升,具有广泛的应用前景。

Objective To explore the application effect of a new type of simulated dermatologic surgical mold based on 3D printing in standardized residency training of dermatology.Methods In this study,35 residents in Department of Dermatology,The Second Affiliated Hospital of Guangzhou Medical University from January 2018 to May 2019 were randomly divided into two groups:a new mold group based on 3D printing(n=18)and a traditional mold group(n=17).Two groups of residents were examined by dermatologic biopsy on the mold,and the effect of teaching was evaluated by questionnaire survey.SPSS 22.0 was used for data analysis,and the measurement data was expressed by(means±standard deviation).The comparison between the new mold group and the traditional mold group was made by two independent samples t test.Results The scores of dermatologic biopsy examination of residents in the new mold group were higher than those in the traditional mold group,and the differences were statistically significant(P<0.01);and the scores of the questionnaires for the teaching effect of the new mold group were higher than those of the traditional mold group,and the differences were statistically significant(P<0.01).Conclusion The new type of simulated dermatologic surgical mold based on 3D printing,which has been successfully applied in the practical training of residents,lays a solid foundation for the actual clinical operation and significantly improves the teaching effect,providing a broad application prospect.
