冻疮和冻伤医学上所说的冻疮和冻伤并不是一回事。低温对人体造成的伤害统称冷伤,冰点(0℃)以下的低温对人体造成的冷伤才是冻伤,而0~10℃的低温对人体造成的则是非冻结性冷伤。冻疮就属于非冻结性冷伤。当软组织受冻并且局部血供减少时所形成的损伤称为冻伤。 Frostbite and frostbite Medical frostbite and frostbite is not the same thing. Low temperature damage to the human body collectively referred to as cold injury, freezing point (0 ℃) below the cold caused by cold damage to the human body is frostbite, and 0 ~ 10 ℃ low temperature on the human body is non-freezing cold injury. Frostbite is a non-freezing cold injury. The damage that forms when soft tissue is frozen and the local blood supply is reduced is called frostbite.
