A gelatin cube ultrasound training model for enhancing the three-dimensional anatomical understanding of blood vessels

Objective:
Ultrasound is widely used in the clinical field. However, training on use of ultrasound is insufficient. Newer models and techniques cannot be introduced for use by doctors without training and knowledge of its clinical utility. We produced a unique ultrasound education model and investigated if the use of the model could enhance the ability of clinicians to use ultrasound.
Method:
A gelatin ultrasound practice model that can be transformed into various shapes was created using a cubeshaped plastic trainer. Residents and interns working in tertiary hospitals were surveyed for their awareness of the use of ultrasound through a questionnaire. Subsequently, ultrasound education was conducted, and a test was administered using a cube-shaped ultrasound education model. After the education and testing, awareness of the use of ultrasound was investigated through a questionnaire once again, and the test results were evaluated.
Results:
A total of 20 people participated in the evaluation and survey using the practice model. Of these, 11 people (55%) had procedural experience of using ultrasound. The Spearman’s correlation test was performed to compare previous ultrasound procedural experience with the number of correct answers, time spent on the test, and the number of attempts, and the results were 0.278 (P=0.235), -0.513 (P=0.021), and -0.369 (P=0.110), respectively. The correlation coefficients between the previous ultrasound knowledge level and changes in the knowledge level, preference, and confidence about ultrasound examination before and after practice were 0.261 (P=0.281), 0.638 (P=0.003), and 0.705 (P< 0.001), respectively.
Conclusion:
Our cube-shaped ultrasound educational model can spark interest in the use of ultrasound, improve knowledge levels, and increase procedural skills in using ultrasound.
