It's time for the year-end rush again, and the cold air seems to be working extra hard. Many places across the country have recently ushered in cold wave weather, and the temperature is expected to continue to be low in the next few days.
Many friends have warmed the baby's body during the day, and the electric blanket protects the body at night, using various "heating artifacts". Everyone knows that in the low temperature of winter, the hands and feet are particularly prone to frostbite. But it is necessary to be vigilant that low temperatures can not only cause frostbite, but also burns.

What is a low-temperature burn?
Many people may wonder if low temperatures can also burn youYou know, low-temperature burns can be more than ordinary burns and scalds "chicken thief"!
Ordinary burns and scalds are usually wounds caused by contact with hot gases, flames, boiling water, etc. This kind of trauma is usually obvious, and it is often "immediate", with immediate pain, immediate blistering, immediate screaming, and easy to detect and avoid.
Low-temperature burns refer to burns caused by prolonged contact with low-heat objects that are higher than body temperature, a bit like "boiling frogs in warm water". The temperature of the human body is generally about 37, when the heat source is higher than the temperature of the human body, and the long-term action may lead to the damage of the soft tissue from shallow to deep.
When our ** is in contact with the temperature of 45 50, such as hot water bottles and warm babies, etc., the sensory nerve endings will not feel the stimulation immediately, but adapt to the contact with the temperature after a long time of contact, which is difficult to detect in time, resulting in heat penetrating into deeper tissues, resulting in aggravated burns. Infants, young children, the elderly, paralyzed patients or drunk people often become "high-risk groups" for low-temperature burns due to their sluggish sensory responses.
Are low temperature burns serious?
Several common heating equipment on the market can reach different temperatures, but on the whole, the average temperature actually used is between 40 and 50, which is in the "high incidence range" of low-temperature burns.
Don't think that "it's good to avoid it if you feel hot", and by the time you feel it, it may have already formed a burn!Although the wound area of this type of burn appears to be small, the pain of the wound is not very obvious, and most of the wounds are only red, swollen, blistered, peeling, and whitish in the early stage.
Compared with high-temperature burns, low-temperature burns often have deeper wounds and are more difficult to heal, often difficult to heal for several months, and severe ulceration will occur, and even necrotic tissue needs to be surgically removed. The severity depends mainly on the time of exposure to the heat source, and the longer the time, the more severe the damage**.
Who is susceptible to low-temperature burns?
General population (students, work groups): deep sleep at night;Drunken state;If your hands and feet are numb when you are cold outside, use a heat source to warm yourself indoors.
Elderly: Older people have a sluggish sensation in the lower limbs, so that the scald is not noticeable until the burn is very severe.
Diabetic patients: insensitivity of nerve endings due to peripheral neuropathy.
Children: Due to factors such as delicate and poor expression ability, it is also easy to cause low-temperature burns.
People with disabilities: Reduced sensitivity to thermal stimuli due to local** sensory decline or impairment.
Burns are immediately "cold treated".
When using heating equipment for a long time, it is found that ** has been red, swollen, peeling or blistered, it means that a low-temperature burn has occurred, at this time, "cold treatment" should be carried out immediately, and the five first aid steps of "flushing, taking off, soaking, covering, and sending" should be opened.
One flush: Rinse the scald area with running cold water for at least 20 minutes as soon as possible to reduce the heat of the surface and reduce further damage to the surface.
Second off: After rinsing and soaking thoroughly, carefully remove clothing in cold water. If the wound sticks to the clothing, cut it carefully to avoid forced tearing.
Three bubbles: If the pain is obvious, it can be soaked in cold water for 10-30 minutes for pain relief. Don't use ice cubes, it's easy to get frostbite!
Four covers: Gently cover the affected area with sterile gauze, if no gauze is available, you can use a clean and dry towel instead. Remember not to cover it with hairy or flocculent items to avoid adhesion to the wound.
Five sends: If there are blisters, or the wound is obviously deep, seek medical attention and send it to the hospital in time!
Don't smear anything without permission. Especially toothpaste, rat oil, soy sauce, red potion, purple potion and other home remedies, don't apply it!
How to prevent low-temperature burns?
All heating artifacts, do not touch the body directly!The correct use of heating artifacts is the top priority to prevent low-temperature burns.
1.Warm baby: It should be pasted through clothes, and a protective cover should be put on before using the hot water bottle and hand warmer.
2.Electric blanket: Do not use it overnight, the temperature should not be too high, it is best to use a temperature-controlled electric blanket.
3.Don't fill the hot water bottle too much, just fill it with about 70% hot water, and the water temperature should not be too hot.
4.Do not stay near heating equipment such as radiators for long periods of time.
