Using simulators in high education enables practical training by repetition in circumstances close to reality reducing the stress of both animal and operator. The limited resources of veterinary schools, the increase in the number of students in lecture halls, and the low availability of animals for teaching due to welfare regulations, reduce teaching opportunities with live animals being simulator as the better alternative. This study aimed to assess the efficacy of a low-cost handmade simulator (SIMCA-COW) in eight veterinary students inexperienced in palpation, ultrasonography evaluation, and artificial insemination in cows.
Two sets of exercises were carried out: structure localization by rectal palpation and ultrasonography were evaluated by the inexpert veterinary students in the SIMCA-COW simulator. Also, evaluated the length of time to insert the insemination catheter through the cervix in the inert simulator during four sessions.
All the students were able to palpate both structures and to locate the body and both uterine horns by ultrasonography. Cervix and follicles were located by 5/8 (62.5%) students and 3/8 (37.5%) students found the corpus luteum by ultrasonography. A reduction in time span between the first and fourth intrauterine insemination attempts was observed (8.26 ± 2.7 vs. 3.69 ± 1.7; mean ± standard error; p < 0.05).
The simulator validated in this study (SIMCA-COW) allows training and learning by repetition, saving the limitations found in live animal practice.
在高等教育中使用模拟器能够在接近真实的环境中通过重复操作进行实践培训,从而减轻动物和操作人员的压力。兽医学校资源有限、讲堂中学生人数增加以及由于福利规定用于教学的动物数量不足,减少了使用活体动物的教学机会,因此模拟器成为更好的选择。本研究旨在评估一种低成本手工制作的模拟器(SIMCA - COW)对八名在奶牛触诊、超声检查评估和人工授精方面缺乏经验的兽医学生的效果。
进行了两组练习:由经验不足的兽医学生在SIMCA - COW模拟器中通过直肠触诊评估结构定位,并通过超声检查进行评估。此外,在四个阶段评估了在惰性模拟器中通过子宫颈插入授精导管的时间长度。
所有学生都能够触诊这两种结构,并通过超声检查定位身体和两个子宫角。5/8(62.5%)的学生通过超声检查定位到了子宫颈和卵泡,3/8(37.5%)的学生通过超声检查发现了黄体。观察到首次和第四次子宫内授精尝试之间的时间跨度有所缩短(8.26±2.7对3.69±1.7;平均值±标准误差;p<0.05)。
本研究中验证的模拟器(SIMCA - COW)允许通过重复进行培训和学习,克服了活体动物实践中发现的局限性。
