During deep frostbite rewarming, how long should the affected area be immersed in a warm water bath?

• A. 2 to 5 minutes
• B. 15 to 30 minutes
• C. 60 minutes
• D. 5 to 10 minutes

Answer: (B)

Deep frostbite rewarming requires a controlled, gradual thaw using warm water to near normal body temperature. Submerging the affected area in water at about 37–39°C for roughly 15 to 30 minutes allows the tissue to thaw properly without causing thermal injury from overheating. This duration is long enough to thaw deeply frozen tissue but not so long that edema, pain, or potential tissue damage from overheating develops. Shorter times won’t adequately thaw the tissue, while much longer times can increase complications. After rewarming, keep the area warm and protected and monitor for sensation return and signs of complication.
