What is the recommended rewarming temperature for frostbite management?

• A. 40 degrees Celsius
• B. 20 degrees Celsius
• C. 60 degrees Celsius
• D. 5 degrees Celsius

Answer: (A)

Rewarming frostbitten tissue is done in warm water to thaw tissue gradually and restore perfusion without causing thermal injury. About 40°C (104°F) is the target temperature because it is warm enough to thaw without burning the skin. Water at this moderate warmth effectively rewarms tissue; hotter temperatures (like 60°C) can cause burns, while cooler temperatures (20°C or 5°C) won’t provide effective rewarming. Rewarm for roughly 15–30 minutes or until the area becomes red and sensation returns, then protect the tissue, avoid rubbing, and ensure there’s no risk of refreezing.
