The purpose of this study was to evaluate learning curves for an existing microsurgical training model. We compared efficiency and amount of training needed to achieve proficiency between novice microsurgeons without operative experience versus those who had completed a surgical internship.
Ten novice microsurgeons anastomosed a silastic tube model. Time to perform each anastomosis, luminal diameter, and number of errors were recorded.
First year residents improved up to a brief plateau at 10 repetitions, followed by continued improvement. Second year residents improved up to a plateau at 10 repetitions with no further improvement thereafter. There was no significant difference in luminal area or errors between groups.
Residents with no operative experience can benefit from early exposure to microsurgical training. These interns continue to improve with additional repetitions while second year residents achieve proficiency with fewer repetitions.
本研究的目的是评估一种现有的显微外科训练模型的学习曲线。我们比较了没有手术经验的新手显微外科医生与完成外科实习的医生在达到熟练程度所需的训练效率和训练量。
10名新手显微外科医生对一个硅橡胶管模型进行吻合。记录每次吻合的时间、管腔直径和错误数量。
第一年住院医生在进行10次重复操作后提高至一个短暂的平稳期，随后继续提高。第二年住院医生在进行10次重复操作后达到平稳期，此后不再有进一步提高。两组之间在管腔面积或错误方面没有显著差异。
没有手术经验的住院医生可以从早期接触显微外科训练中受益。这些实习生随着重复操作次数的增加而持续提高，而第二年住院医生则通过较少的重复操作次数达到熟练程度。
