定义
冻伤是因接触冷空气、液体或金属在组织内形成冰而造成的损伤。最常见原因是皮肤过度暴露于零度以下的环境温度。风加剧了受伤风险。最常见受累部位是手指、脚趾、耳朵、鼻子、脸颊和下巴，损伤仅限于皮肤和软组织。长期暴露在寒冷环境中，可能会出现全层皮肤坏死和包括肌肉和骨骼在内的深层结构损伤。
Frostbite is injury from ice formation within tissues resulting from contact with cold air, liquids or metals. It is most commonly due to excessive exposure of skin to sub-zero environmental temperatures. The risk of injury is exacerbated by wind. The most commonly affected sites are fingers, toes, ears, nose, cheeks and chin with injury limited to skin and soft tissues. Full thickness skin necrosis and injury to deeper structures including muscles and bone may occur with prolonged exposure to cold.
