Paper Abstract

Yucatan mini-pigs and Yorkshire pigs were exposed on their flanks to 1318 nm, 0.5 ms laser pulses. Injuries were readily visible on the Yorkshire pigs immediately, one hour, and 24 hours post exposure but difficult to locate at 3 days post exposure. The Yucatan mini-pig injuries were not seen immediately or at one-hour post exposure, but at 24 hours and three days post exposure they were easily identified. The Yorkshire injuries were round red, well demarcated, with a circular pink area of edema. It is hypothesized that skin pigmentation has an effect on the mechanism of 1318 nm laser energy absorption in skin. Pigmentation may have a significant effect on how infrared laser injuries present, develop and heal.
