Assessment of a Low-cost Canine Uterine Simulator as a Tool for Teaching the Ovariohysterectomy Technique to Veterinary Students.

The acquisition of skills to perform an ovariohysterectomy (OVH) is crucial for veterinary medicine students. It has been demonstrated that the most effective way to develop these skills is through repetitive training on simulators. Unfortunately, commercial simulators are expensive, limiting their use and highlighting the need for the development of more cost-effective alternatives. This study aimed to assess the effectiveness of a low-cost, easily constructed textile-based simulator for the canine ovaries and uterus in training veterinary students on the OVH technique. The impact of tutor guidance on student learning was also assessed. Participants were divided into two groups: simulator and tutor guidance (SG) and simulator only (SO). Each student performed 20 repetitions of the three-clamp OVH technique, and the number of errors and execution time were quantified. The SG group reached the learning curve plateau in terms of minimum errors on the 7th repetition and attained the fastest time on the 6th repetition. The SO group reached the learning curve plateau in terms of minimum errors and attained the fastest time both on the 15th repetition. From individuals in the SG group, there were no requests for tutor guidance from the 11th attempt. This low-cost simulator is ideal for training veterinary students in the early stages of surgical learning, as it effectively facilitates learning the OVH procedure without the use of live animals.
