PRODUCTION OF EXPERIMENTAL BURN - A CRITICAL TECHNICAL EVALUATION - STUDIES IN BURNS .V.

A detailed comparison was made of the effects on logomorphs of 15 methods of burning, including radiant heat, flame, branding, and scalding at 4 separate temperatures and 3 different distances. Response of the surface to hyperthermic insult was observed with regard to thermo-temporal alteration, change in thickness, and variation in water-retentive capacity of the challenge site. Branding with a 730°C. Pyrex disc produced the greatest surface damage, but exposure to open flame and 15-second immersion in 100°C. or 90°C. water were statistically comparable. Sealding at 70°C., although followed by transient skin thickening, produced no significant alteration by 3 hours postburn. These studies demonstrated a clear inverse relationship between surface thickness and water-transmission function. These observations were related to the selection of experimental techniques, the interpretation of experimental results, and the understanding of some of the manifestations of the clinical burn. © 1969.
