The Change of Surface Temperature in Healing Process of Wound and Burn in Porcine Model

ABSTRACT

PURPOSE: The goal of wound managements are to prevent further tissue injury during dressing changes, and absorb the excessive exudates, provide moist condition, reduce the infection. But the usual dressing methods have several limitations to serve the information about wound surface environment. Moist, pressure, temperature, pH are the important factors that give us the information about the healing process phase, speed of healing, & the risk of infection. METHODS: We made full thickness wounds & burn on porcine model, then assessed the surface temperature intermittently until repithelialization were completed, and size measurement were done with Image Pro Plus 6.0. RESULTS: In wound areas, the surface temperature was lowest at post operation #1 day, then slightly increased till POD #21 days, and again down slope curvature. In burn area, the surface temperature was highest at POD #1 day, then slightly decreased till POD # 21 days, and more fall curvature. Modern sensing technology along with wireless radio frequency communication technology is posed to make significant advances in wound management. Our result will be a basic data for the future researches about the surface temperature monitor to detect the early infection and the intervention to modulate the surface temperature to increase the rate of epithelialization. CONCLUSION: The result of the correlation between the surface temperature and area reduction have weak or moderate negative Pearson correlation coefficient.
