Training of Veterinary Students in Trans Rectal Palpation of Equids: A Comparison of Live Versus Cadaver Models

Abstract

Transrectal palpation (TP) is a basic skill in equine practice. Traditional TP learning methods include instructor-assisted TP in live animals, but this approach presents animal welfare concerns, especially when it needs to be used with large numbers of students. The main objective of this study is to compare two learning methods of TP: traditional methodology with live horses (LH) and alternative methodology using a cadaver with its flanks dissected (CDV). Twenty students with no previous equine TP experience were randomly assigned to two groups: LH ( n = 10) and CDV ( n = 10). Both groups received initial theoretical training before the LH or CDV session. Learning outcomes of both groups were assessed in a new TP session with live horses. All students were asked about their success in palpating seven intra-abdominal structures and objective ultrasound confirmation (UC) was also performed. Successful perception in palpation and by UC was similar in both LH and CDV students’ groups, without significant differences. Anonymous surveys answered by these 20 volunteers and by 126 students enrolled in the regulated course who also received this CDV training showed very positive feedback on the CDV methodology. As a limitation of the study, there were few students in each group and most of the results are based on subjective criteria. Nevertheless, we can conclude that CDV is a useful tool for teaching TP, with good learning results, allowing the instructor to see what the student is touching and avoiding the LH disadvantages.
