[Rational use of animal models for research and microsurgery training].

The objective of this study is to disclose an experimental model of low cost, which complies with the regulatory norms of animal experiments by using dead animals from other experiments, contributing to the improvement of microsurgery learning. Cadavers of Wistar rats, originated from disposal of other courses, are used. The corpses of thawed mice are used for basic microsurgical training of medical students at the Nove de Julho University, aiming to contribute to the students' training. Their use is justified by the low cost of the material used, many animals being spared during the intermediate phase of skill development for realization of micro-anastomoses. This experimental model is inexpensive and allows the rational use of animals, corroborating with the ethical standards of experimental research and contributing to the education and training of microsurgery.
