DEVELOPMENT OF A PLASTINATION PROTOCOL FOR THE PRESERVATION OF BOVINE HEARTS
Abstract
An alternative and cost-effective protocol for plastinating anatomical specimens, focusing on a bovine heart as a model, is presented. The importance of Veterinary Anatomy and the risks associated with formaldehyde use in tissue preservation are emphasized. Additionally, the crucial role of technology in education, particularly plastination, as an emerging technique for preserving organic tissues, is highlighted. The aim was to develop an alternative protocol to the German standard for plastination using a bovine heart, adapting it to improve accessibility and safety. The method involved several stages, from formaldehyde fixation to curing with polyester resin and styrene monomer, detailing each step from the selection of anatomical material to final curing. The use of thinner instead of acetone is underscored due to constraints and costs. As a result, although some cracking attributed to the thinner was observed, a durable plastinated piece suitable for teaching purposes was obtained. It is concluded that the proposed protocol offers a safe and effective alternative for plastination, with didactic results and morphologically similar outcomes to fresh specimens. The importance of continuously adapting and improving anatomical techniques to meet educational needs and reduce risks for students and veterinary personnel is highlighted.
