Human cadaver model as a training tool for enzymatic burn debridement (Nexobrid®): A feasibility study

Abstract

ObjectivesTo determine the feasibility of using human cadavers to demonstrate enzymatic burn debridement, as a training aid for clinical staff. Material and methodsA single, fresh-frozen human cadaver was used. Prior consent had been given. Burns were created by flame and scalding. Unburned control sites were also assessed. Nexobrid® enzymatic burn debridement paste was applied to all sites, in adherence to the local clinical protocol for treating burned patients. After removal of Nexobrid®, wounds were assessed to determine if the cadaveric tissue appeared similar to what would be expected in living burned patients and whether the technique could be viable for training of burn care staff. ResultsNexobrid® had a very similar effect upon burned cadaveric skin to what would have been expected in living burned skin. Burns of partial thickness burn depth and full thickness burn depth were debrided and could be clearly identified. ConclusionsFresh-frozen human cadaveric tissue is a valid means of provision of training in the technique of enzymatic burn debridement. This finding was unexpected and shows that our understanding of the mechanism of action of Nexobrid® is incomplete.
