Early Assessment of Burn Depth with Far Infrared Time-Lapse Thermography.

Background: Diagnosing the extremes of superficial burns and full-thickness burns is straightforward. It is in the middle ground of partial-thickness burns where the diagnostic difficulties emerge; it can take up to 3 to 5 days for signs of healing to appear. We hypothesize that cooling partial-thickness burns and tracking the rate of rewarming will immediately reflect the condition of the burn: shallow partial-thickness burns that retain cell health and blood flow will rewarm rapidly, and deeper burns with damaged microvessels will rewarm slowly.
