Simulador acústico para la enseñanza en el grado de ejecución de biopsia guiada por ultrasonografía

Abstract

Learning surgical procedures entails the acquisition of techniques and manual skillsin models before performing them on patients. Acoustic simulators (AS) available inthe market are too expensive to be used for teaching purposes and as they becomedeteriorated after successive practices, they are discarded. The aim of this work

was to evaluate the acoustic properties and viability of an acoustic simulator madeby the authors to be used in undergraduate teaching of ultrasound-guided centesisprocedures. Each simulator was made up of a gel medium which contained a boiledegg that simulated the neoplasia to be punctured. These acoustic simulators weregiven to 13 advanced students of Veterinary Medicine. The freehandultrasound-guided centesis technique was taught to the group of students and anAS was handed to each one of them. After the experience, they answered aquestionnaire to evaluate the experience. All the students identified the neoplasia onthe ultrasound monitor and coordinated the manual skills to guide the needle inorder to perform the procedure. Our model met the acoustic and ecogenicconditions necessary to be used for the training and learning of ultrasound-guidedcentesis
