摘要

目的　探讨“理论授课-离体-在体-总结-离体-在体-考核”双循环强化训练模式（dual-cycle intensive training mode，DCITM）相对于传统“理论授课-离体-在体-考核”单循环基础训练模式（basic training mode，BTM）在心血管外科专业学位研究生手术基本技能培训中的效果。方法　8名心血管外科专业在读研究生依次接受BTM和DCITM小班冠脉搭桥血管吻合术基本技能培训，然后以专家评分方式对培训效果进行评价，采用SPSS 17.0统计软件对评价结果进行分析。结果　与BTM比较，DCITM培训出来的研究生手术技术更加娴熟。在小型猪离体心脏冠脉吻合中，规定时间内人均完成吻合口数量明显增加[（2.0±1.0） vs. （5.0±1.5），P＜0.05]，血管渗漏率明显降低[（92±5）% vs.（30±2）%，P＜0.05]，每个吻合口的平均用时明显缩短[离体：（20.1±2.5） min vs.（12.6±3.3） min，P＜0.05]；而在小型猪在体冠脉血管吻合中，不同方法培训后每个吻合口的平均用时差异也有统计学意义[在体：（30±2）min vs.（21±3）min，P＜0.05]。结论　DCITM是一种值得推广的高效优化心血管外科专业研究生教育教学质量、增强临床手术技能训练效果的模式

Abstract

Objective　To compare the effects between the dual-cycle intensive training mode (DCITM) of teaching-in vitro-in vivo-summary-in vitro-in vivo-assessment and the single-cycle basic training mode (BTM) of teaching-in vitro-in vivo-assessment on training graduate students majoring in cardiovascular surgery. Methods　Eight graduate students majoring in cardiovascular surgery received the basic training of coronary artery bypass vascular anastomosis under the mode of BTM or DCITM. Then the training effects were evaluated by scoring of experts. Besides

SPSS 17.0 statistical software was used to analyze the evaluation results. Results　Compared with students who received BTM

the postgraduates trained by DCITM became more skilled in vascular anastomosis. In vitro

the average number of anastomosis completed by trainee increased significantly [(2.0±1.0) vs. (5.0±1.5)

P<0.05] over a specified period of time

the vascular leakage rate was significantly reduced [(92±5)% vs. (30±2)%

P<0.05]

and the average time per anastomosis was significantly shorter [in vitro: (20.1±2.5) min vs. (12.6±3.3) min

P<0.05]. There was also a statistically significant difference in the average time of each anastomosis in miniature pigs with coronary vascular anastomosis [in vivo: (30±2) min vs. (21±3) min

P<0.05]. Conclusion　Taken into together

DCITM is a highly efficient mode for promoting the quality of cardiovascular-surgery-teaching and enhancing the effectiveness of training in clinical surgical skills.
