The afflicted part should be moved gently and voluntarily during rewarming. A dull purple color indicates more serious injury and requires medical attention. So does swelling or blisters. Other means for improving circulation are available but must be administered by medical personnel. Summary Most cases of frostbite occur as a result of lack of knowledge, careless preparation, unavoidable accident, or the effects of alcohol on judgment.
Intelligent forethought can prevent injury.
If freezing does occur, proper rewarming in warm water will give maximum benefit. The injured limb should be handled gently and a medical judgment be made of the extent of the injury and the need for further treatment.
