In frostbite management, what is a risk of rewarming if there is active refreezing risk?

• A. It can cause tissue damage
• B. It will always heal without complications
• C. It can cause tissue damage if refreezing risk exists
• D. It has no effect on outcome

Answer: (C)

Rewarming frostbitten tissue aims to restore blood flow and limit tissue death, but it must be done only when there’s no risk the tissue will refreeze. If refreezing could occur, warming the part can actually cause more damage. When the tissue thaws, blood flow returns and cells become vulnerable; if it cools again, ice crystals can reform and grow, tearing cells, injuring the microvasculature, and triggering more edema and pain. That cycle can worsen tissue loss and necrosis, so in situations where refreezing is possible, rewarming may increase harm rather than help. This is why the correct statement is that rewarming can cause tissue damage if refreezing risk exists. The other ideas either oversimplify the outcome or ignore the conditional risk, so they don’t fit as accurately.
