When it comes to burns, many people think of high temperatures and high heat, and the most common is being burned by boiling water, rice soup, stove, etc. Feng Qin, Department of Cosmetic Plastic Surgery and Burn Surgery of the First Affiliated Hospital of Chengdu Medical College, said that in fact, in addition to this common burn, there is also a kind of low-temperature burn.
Feng Qin reminded that as the weather gets colder, there are more and more heating equipment, and the cases of low-temperature burns in winter are also increasing, "For example, some people like to put hot water bottles in the quilt to warm up when they sleep, but after sleeping, because they are not sensitive to the outside temperature, the parts attached to the hot water bottle may cause low-temperature burns due to long-term non-change of position." ”
Burns at low temperatures. Easy to overlook.
According to Feng Qin, low-temperature burns refer to the body's long-term exposure to a heat source at a moderate temperature, resulting in progressive damage from the superficial dermis to the deep dermis and subcutaneous tissues, and the degree of damage is positively correlated with the contact time.
People with low temperature burns, partly because of improper heating, mostly for the elderly at home and young students in school, due to limited conditions or living habits, the use of hot water bottles, warm babies, hot compresses and other long-term direct contact ** heating, some often use all night, wake up, find that they have been burned. Feng Qin said that part of it is because of the lack of perception and improper patient care, such as people who are unconscious in some limb parts, diabetic patients, amputee patients, in order to relieve the cold extremities of the limbs, family members or accompanying staff use warm water bags, hot water bottles, etc. to pad under the limbs, and cause burns caused by long-term contact. In addition, there are some people who do traditional Chinese medicine moxibustion and physics, because the safety distance and time are not well controlled, improper operation, etc., resulting in low temperature burns.
Feng Qin said that low-temperature burns are different from high-temperature burns, and the pain of the wound is not very obvious, and only redness, swelling, blisters, peeling or whitishness appear on the **. The area of low-temperature perm is often not large, and the surface does not seem to be serious, but the wound is deep, and in severe cases, it can even cause deep tissue necrosis. "It is easy to ignore the surface of a low-temperature burn because it is not too serious, but if it is not treated properly after a low-temperature burn, it may be complicated by infection, deepen the wound, and even form a chronic ulcer. ”
Heating in winter. Pay attention to the time and temperature of use.
First of all, cool down. Immediately after a low temperature scald, rinse the scalded area with cold water to reduce the temperature of the wound, relieve pain and minimize the damage of the scald, if the phenomenon of scalding peeling is found, use soaking to cool down, and the cooling time should be 15 to 20 minutes is the best.
Secondly, disinfection and sterilization. After cooling, use iodophor or normal saline for disinfection and sterilization to avoid wound infection.
Finally, apply an appropriate amount of medicine. Applying an appropriate amount of burn cream can effectively relieve pain and promote the repair of wound cells. As a reminder, don't apply toothpaste, soy sauce or even tobacco ash, as these treatments are not only useless, but can easily cause infection.
Feng Qin said that if you find that the scald is more serious, the ** of the scald part is reddish-brown or gray, and the scald area is too large to deal with by yourself, it is recommended to seek medical attention immediately**.
How to prevent low-temperature burns?Feng Qin gave three suggestions: First, when using heating equipment such as electric warm blankets, we should pay attention to product quality, purchase qualified products, control the use time, and operate in strict accordance with the instructions. Turn it on before bedtime and turn it off at bedtime. Second, when using baking lamps, ultraviolet lamps, warm compresses, cupping, moxibustion, medicinal baths, etc., it is necessary to strictly control the time and temperature. Third, people with physical fatigue, heavy drinking, the elderly, children, diabetics, and paralysis should try to avoid and reduce the use of warm products and ** that are easy to cause low-temperature burns.
