摘要

在这项研究中,塑化标本被用来创建一个学习模型,以帮助学生了解狗的常见心脏病理。扩张型心肌病是一种心肌疾病,引起所有四个心室进行性扩张,并伴有收缩功能的改变。研究人员使用了狗心脏的两个塑化切片,一个来自一只健康的狗,另一个来自一只患有扩张型心肌病的狗。对塑化切片进行拍照和数字化,然后使用静态图像动画程序模拟心跳,以可靠的方式进行。这些数字材料被用来制作一个视频教程,在视频教程中,心脏的结构同时在解剖和超声图像中突出显示。视频教程是通过二维码访问的,发给了一组兽医学位课程的学生,他们之前接受过超声诊断的基础培训。满意度调查用于监测每个学生对临床解剖学重要性的认知,以及视频教程的使用和学习经验。结果显示,大多数学生认为解剖学是他们职业生涯的基础学科,尽管他们在学位结束时对解剖学的了解并不太广泛。视频教程的总体得分非常高,因为它显然有助于理解扩张型心肌病的超声成像。结论:塑化材料与网络学习相结合,提高了学生对学习的主观感知和对扩张型心肌病的认识。

A digital resource based on plastinated specimens for learning dilated cardiomyopathy in dogs
In this study, plastinated specimens were used for creating a learning model to assist students’ understanding of a common cardiac pathology of dogs. Dilated cardiomyopathy is a myocardial disease, causing a progressive dilatation of all four cardiac chambers, with concomitant changes in systolic function. Two plastinated sections of canine hearts were used, one from a healthy dog, and the other belonging to a dog affected by dilated cardiomyopathy. Plastinated sections were photographed and digitized, and then a static image animation program was used to simulate the heartbeat, in a reliable manner. The digital materials were used to create a video tutorial, in which the structures of the heart were simultaneously highlighted in both anatomical and ultrasound images. The video tutorial was accessed via QR code, which was given to a set of students of the Veterinary Degree Program with previous basic training in ultrasound diagnosis. A satisfaction survey was used to monitor each student's perception of the importance of clinical anatomy and the usage and learning experience with the video tutorial. The results reported that most students considered anatomy as a fundamental subject for their professional career, although their knowledge about it at the end of the degree was not too extensive. The overall score of the video tutorial was very high, as it apparently facilitated the understanding of ultrasound imaging related to dilated cardiomyopathy. It is concluded that the combined use of plastinated material with e-learning improved the subjective perception of learning and understanding of the dilated cardiomyopathy by the students.
