Additionally the mean temperature gradient after cold exposure was reduced after laser irradiation, while the number of fingers showing prolonged rewarming was unaffected.
Slow rewarming is undertaken when hypothermia is present.
More damage can occur when rewarming is slow or the affected area is warmed and refrozen.
Many patients experience severe pain in the affected part during rewarming treatment and an intense throbbing pain that arises two or three days later and can last days or weeks.
In most cases, the child will be hospitalized to monitor the rewarming process and to do the necessary tests needed to determine the extent of the frostbite.
