Pilot Study Evaluating Three Light‐embalming Solutions for Preparation of Cadavers for Short‐term Medical Training Courses

Abstract

A need for cadaveric tissue that is pliable and more realistic than traditionally embalmed material for teaching and practicing surgical and emergency medical techniques necessitates an embalming technique that elicits life‐like physical characteristics and temporary prevention of tissue decomposition. This pilot study seeks to identify a short‐term “light” embalming technique to produce cadaveric tissue comparable to fresh tissue for usage during week‐long surgical courses. In our pilot study, embalmed cadavers are prepared with one of three different solutions containing varying concentrations of primary embalming agents (Dodge Plasdopake, Aardbalm, and Wessels) and accessory chemicals. Range of motion, rate of decomposition, and resemblance to fresh tissue in surgical practice are being measured blindly on these specimens and un‐embalmed cadavers. Preliminary results suggest that while cadavers embalmed with Aardbalm are rated highest among clinicians in resemblance to fresh tissue, the rate of decomposition is rapid. A solution of both Dodge and Wessels fluids initially shows promise in producing cadaveric tissue that is comparable to fresh tissue in range of motion, tissue consistency, and neurovascular architecture while resisting rapid decomposition. Data collection is ongoing and preliminary findings will be presented in full at the current meeting.
