What is the recommended frostbite management for an affected finger?

• A. Do not rub; remove rings and jewelry; rewarm in 40–42°C water until color returns and sensation recovers; protect with sterile dressing; avoid refreezing
• B. Rub briskly to generate heat
• C. Soak the finger in 15–20°C water
• D. Massage with oil after rewarming

Answer: (A)

Gentle, controlled rewarming is the key to frostbite management for a finger. The goal is to restore perfusion without causing further tissue injury.

First, remove rings or jewelry on the affected finger so swelling won’t constrict circulation after thawing. Then rewarm in circulating water at about 40–42°C (104–108°F) until the color returns and sensation comes back, which typically takes several minutes to a quarter of an hour. This warming should be continued until normal warmth and sensation are regained, not with quick or uneven heating.

After rewarming, protect the finger with a dry sterile dressing and avoid breaking any blisters. Do not refreeze the tissue—if there's a risk of refreezing (return to a very cold environment), avoid thawing or delay warming until it can be protected from freezing.

Avoid rubbing briskly, massaging, or using oils or other substances on the tissue, and steer clear of soaking in cooler water or applying direct heat. These actions can cause more damage to already vulnerable tissue. If there are signs of more severe frostbite or persistent numbness, seek medical care.
