Evaluation of an Equine Nasogastric Intubation Model for Training Veterinary Students

Simulation in veterinary education is an important means of providing a safe, welfare-friendly way for students to hone their skills prior to performing procedures on live animals. Students may not get many chances to practice passing a nasogastric tube and checking for reflux in live horses during clinical rotations and extramural studies. A low-cost equine nasogastric intubation model was created at the University of Surrey, allowing students to practice passing a tube and checking for reflux. Thirty-two equine veterinarians evaluated the model for realism and its potential usefulness in teaching. Veterinarians found the model to be realistic, supported its use as a teaching aid, and provided helpful feedback for possible improvements. In addition, 83 year-4 veterinary students rated their level of confidence before and after using the model for nine specific aspects of nasogastric intubation. Students showed significantly increased confidence levels in all nine aspects after using the model, and reported that they appreciated being able to practice the skill in a safe environment prior to performing it on a live horse. The results of this study suggest that both clinicians and students considered that this model has educational value, which supports its use for training veterinary students prior to clinical placements. The model provides an affordable, robust educational aid that can be used in clinical skills teaching, increases student confidence, and allows students to practice the skill repeatedly.
