Value of artisanal simulators to train veterinary students in performing invasive ultrasound-guided procedures

Abstract

Pericardial effusion can lead to cardiac tamponade, which endangers an animal's life. Ultrasound-guided pericardiocentesis is used to remove abnormal liquid; however, it requires technical expertise. In veterinary medical education, the opportunity to teach this procedure to save lives during emergencies is rare; therefore, simulators are recommended for this practice. The present study aimed to create a model that can be made “at home” at low cost for ultrasound-guided pericardiocentesis training and to gather feedback about this model through questionnaires given to the participants. Eighteen professionals and thirty-six students were introduced to the simulator in pairs. After the simulation training session, participants filled out the questionnaire. Participants considered the model strong in the following areas: visualization of the pericardium, the heart, fluid in the pericardium, and fluid decrease during fictitious pericardiocentesis and its realism. They considered the model weak or moderate in the following areas: visualization of the surrounding tissues, difficulty of pericardial puncture, and visualization of the catheter. The professionals classified the realism of the experimental heart as moderate, whereas the undergraduate students classified it as strong. All participants believed that the experimental model could be useful in preparing for a future real situation. This model fulfills the need for a practical, realistic, and cost-effective model for ultrasound-guided pericardiocentesis training.
