In the cold winter, many people love to use warm babies, hot water bags and other supplies to keep warm. Recently, there has been a significant increase in the number of patients with low-temperature burns, nearly twice as many as before, and the patients are mainly the elderly, infants and young children, diabetic patients, paralyzed patients and other groups of people who are not sensitive to heat sources. Low-temperature burns because the heating equipment at the beginning of the base temperature is not particularly high, such as 60 ℃ hot water bag, wrapped in a towel to hold on the body or resting on the feet to warm up, indeed a moment will not have the burning sensation of ordinary scald like. Because of this, the body is more difficult to respond in time. But once a location of the body for a long time to accept this kind of higher than the body temperature of the low heat object, up to a certain time may also be scalded, this is the low-temperature burns. “40 ℃ for five or six hours on the skin can cause low temperature burns.” Low-temperature burns as “stewed meat”, on the surface looks like a small area, the feeling is not serious, but in fact almost all deep burns, not only the surface layer of the skin is seriously damaged, and sometimes may be burned to the subcutaneous fat layer or even the muscle layer, the area of a slightly larger area of low-temperature scalded often need surgical treatment to heal.
