背景资料：微血管手术现在是许多外科学科的一个组成部分，这些手术的成功依赖于外科医生的技术技能。虽然已经开发了许多训练模型和模拟，但活体大鼠模型因其对临床显微手术的高度逼真性而受到青睐。然而，使用真人模特进行培训存在严重的道德问题。本研究的目的是证明，如果有效的技能获取是可能的，减少活rates.Methods的数量：两个课程结构的设计，实施。两个疗程的总训练时间保持不变，但使用的大鼠数量从传统的每名参与者5只大鼠减少到A组的4只和B组的3只，同时增加了在合成和离体模型上花费的训练时间。我们通过比较通畅率、每次吻合所需时间和大鼠利用率的效率来评估课程的有效性。结果：A组有30名参与者，B组有28名参与者。我们观察到，B组能够进行吻合术在一个显着更短的时间和通畅率类似于A组，尽管在training.Conclusions中使用的大鼠数量较少：我们能够最终证明，这是可能的，以减少活鼠使用显微外科培训，而不影响培训的质量。
Background: Microvascular surgery is now an integral part of many surgical disciplines, and the success of these procedures relies on the technical skills of the surgeon. Although numerous training models and simulations have been developed, the living rat model is favoured for its high fidelity to clinical microsurgery. However, there are serious ethical concerns over the use of live models for training. The aim of this study was to demonstrate if effective skill acquisition was possible with a reduction in the number of live rats.Methods: Two course structures were designed, that were implemented. Total training hours remained the same in both the courses, but the number of rats used was reduced from conventional five rats per participant to four in group A and to three in group B while increasing the training time spent on synthetic and ex-vivo models. We assessed the effectiveness of the courses by comparing the patency rates, the time taken per anastomosis and efficiency of the utilisation rate of rats.Results: There were 30 participants in Group A and 28 participants in group B. We observed that group B was able to perform anastomosis in a significantly shorter time and with patency rates similar to group A in spite of a lesser number of rats used in the training.Conclusions: we were able to conclusively demonstrate that it was possible to reduce live rat usage in microsurgical training without compromising on the quality of training.
