In order to prevent an anesthetized patient's body temperature from decreasing in the operating room, a mat with warm water circulation is often used. However, burn injuries sometimes occur on a patient's body in spite of the correct use of the mat. The cause of this injury has not yet been clarified. In this study, heat transfer between the bio1ogical tissue and the mat was calculated numerically under the condition of heat transfer by blood flow. The effects of the thickness of biological tissue, water temperature, heat transfer coefficient of the water flow in the mat, metabolic heat production rate, and blood perfusion rate distribution on heat transfer in biological tissues were clarified. From the standpoint of these effects, the conditions of occurrence of burn injury were examined. Results indicated that the model in this study was capable of simulating the mechanism by which burn injuries in the operating room are caused.
