What is a cautious approach to rewarming frostbitten tissue in the field?

• A. Aggressive rewarming in field
• B. Rewarm with hot water
• C. Avoid aggressive rewarming if the patient cannot be kept warm and safe; rewarm only in controlled environment and with pain control
• D. Do nothing

Answer: (C)

Rewarming frostbitten tissue should be approached with caution because thawing in an uncontrolled setting can cause more damage than benefit. In the field, aggressively thawing the tissue or using methods that aren’t controlled—like hot or very hot water, rough rubbing, or rapid temperature changes—can increase pain, cause tissue injury, and raise the risk of complications such as edema, infection, or refreezing if exposure to cold resumes later. The safest plan is to avoid rapid rewarming unless you can keep the patient warm and safe and provide pain management and monitoring. Instead, protect the affected areas from further cold, keep the patient dry and insulated, and arrange rapid transport to a controlled environment where rewarming can be performed with appropriate analgesia and supervision. If rewarming does occur, do it under medical control, typically using moderated warmth and careful monitoring to minimize harm.
