Preservation of Cadavers for Surgical Technique Training

Abstract

To evaluate a technique for preservation of organoleptic tissue characteristics (color, odor, texture, and flexibility) in cadavers used for surgical instruction. Experimental study. Forty-three canine cadavers. Cadavers were preserved with a modified Larssen solution of the Hospital Cochim, Paris and cryopreservation. Tissue handling qualities were evaluated in surgical laboratory sessions. All cadavers kept texture and tissues consistency, especially skin and muscle, similar to those of live animals. Some skin desquamation and pallor of the mucous membranes occurred with repetitive freeze-thaw cycles. This preservation technique provides acceptable cadaver quality and tissue handling for use in surgical instruction. Preparation of patient cadavers by intravascular injection of modified Larssen solution yielded suitable instructional models for surgical training.
