Bleeding simulation in embalmed cadavers: bridging the gap between simulation and live surgery.

In veterinary medicine, surgical education and training require the development of abilities that can be acquired in practical classes using currently available models such as cadaver training. Limited availability of cadavers, undesirable changes in tissue texture and the absence of bleeding are the main disadvantages of cadaver-based training compared to training in live animals. This study proposes a chemical cadaver preservation method aimed at overcoming the aforementioned limitations. Blood circulation could be reproduced in preserved cadavers, thereby enabling satisfactory simulation-based training of several surgical procedures, from incision to suture and including hemostatic techniques. The model in this study introduces a high-fidelity simulation training alternative to prepare students for the practice of surgery. In this manner, surgical interventions would be restricted to surgical cases and healthy animals would not be submitted to surgical procedures exclusively for learning purposes.
