The temperature in Beijing is the lowest since 1966.

Parents are afraid that their children will catch cold.

In addition to wrapping the child in three layers, there are three layers outside.

Also began to look for all kinds of "heating artifacts"

For example, warm baby, hot water bottle ...

However, although "artifacts" can bring warmth and comfort.

Once used improperly.

It may make the baby "very hurt"

"Low temperature burn" is a frequent season.

Silence is harmful.

A few days ago, Ms. Zhang of Hangzhou was afraid that her daughter was too cold, so she washed a hot water bottle and put it on the bed before going to bed. As a result, when I woke up, my daughter had a rash and blisters on her leg, which still hurt to the touch.

After careful observation and inquiry by the attending doctor, it was judged that "cryogenic burns" was caused by a thermos bottle.

Coincidentally, Zhou Xiao, a girl in her early twenties, is also one of the patients with low temperature burns.

In winter, Zhou Xiao likes to hoard a lot of "warm babies", and putting one sticker a day has become her winter routine. But as time went on, she found that her stomach began to turn red, and then gradually evolved into blisters, peeling and ulceration.

What? How can you burn at low temperature?

Although the temperature of most heated materials is usually kept within the range that ordinary people can tolerate or even be comfortable, long-term exposure will still lead to low-temperature burns.

What is "low temperature burn"?

"Low-temperature burn" refers to the gradual damage from the superficial dermis to the deep dermis and subcutaneous tissue after long-term exposure to a heat source of moderate temperature (generally 44-50℃).

When using heating materials, because the temperature is not too high, the sensory nerve endings of the skin gradually adapt to contact with the temperature of the heat source, and some people have no obvious pain or even pain. However, in the continuous heating with low heat energy, the skin surface tissue will gradually dehydrate under the action of heat energy, causing damage, so cryogenic burns is often not easy to be found.

The harm of low temperature burn should not be underestimated.

Different from "high temperature scald", the pain of "cryogenic burns" is not obvious, and only symptoms such as erythema, edema, blistering and peeling appear, and the area is relatively small. But it is precisely because the temperature is not high that the wound is difficult to detect. By the time the symptoms really appear, the degree of skin damage is already very serious.

Data display:

49 The skin will be damaged if the heat source keeps in contact with the skin for 3 minutes, and the skin of the watch will be necrotic after more than 9 minutes;

Continuous contact with heat source for 6 hours can cause irreversible skin damage;

The damage degree is positively correlated with the contact time at 44-5 1.

Prevent "low temperature burns"

Do four things well

1

Scientific procurement

First of all, no matter what kind of heating items, they should be purchased from formal channels and used correctly according to the product instructions.

hot-water bag

The quality of hot water bottles on the market is uneven. Some fake and shoddy products have poor latex quality and poor heat insulation effect. In addition, the use of latex for too long aging, easy to cause burns. In addition, if the embolus is not well sealed, hot water will flow to the skin and cause burns.

electric bottle

There are two kinds of electric hot water bottles, one is electric heating wire (tube) type electric hot water bottle, and the other is electrode type electric hot water bottle, which is easy to explode. At present, the country has clearly listed "electrode electric hot water bottle" as a prohibited product.

Check your electric hot water bottle quickly: pinch it gently with your hand. If you can touch a mesh object or a very obvious arc coil device, it is an electric hot water bottle with a heating wire; If you pinch a big U-shaped or two hard cylinders, it is an electrode electric hot water bottle, which needs to be thrown away immediately!

Warm baby patch

Generally speaking, warm babies made of regular materials should be certified by national quality inspection. However, in order to reduce the cost, some inferior warm babies produced in small workshops may use industrial scrap iron powder, which may bring risks such as radiation.

2

controlling temperature

The higher the temperature, the greater the damage. When using the hot water bottle, you can wrap a towel outside to prevent direct contact with the skin, including warming the baby, and you can't stick it directly on the skin.

Similarly, when using other heating equipment, the heating temperature can be appropriately reduced, such as setting the electric blanket to a low heat level and adding sheets or thin bedding.

three

control time

Avoid heating items touching the same place for a long time.

When using warm baby stickers, you can take them off every once in a while and put them in different positions;

When using hot water bag or electric blanket, you can warm up before going to bed, and then turn off the power or take out the heating items after the bed is warm;

When using an electric heating fan or radiator, don't blow at the same part of the body for a long time.

four

Strengthen nursing care

As a guardian, you must take good care of your children and observe their skin condition at any time after giving them heating materials.

Infants and young children, in particular, have delicate skin, are extremely sensitive to temperature and have poor expressive ability. If adults don't take care of it properly, it is easy to cause burns.

Don't believe in "folk remedies"

Please remember the "five-character formula"

If the child accidentally burns at low temperature, and the skin becomes red, swollen and blistered, it must not be considered as a trivial matter. Don't go to the doctor, and don't rub toothpaste and garlic outside, or try to break the blisters with acupuncture.

These wrong practices will not only increase the chance of wound infection, but also increase the difficulty of treatment when seeking medical treatment, and will also affect the doctor's observation and judgment of burn depth.

Please remember the correctly handled "five-character formula".

1

rush

Immediately carry out "cold treatment"! Rinse or soak the wound with clean cold water (15-20 c) as soon as possible 10-30 minutes.

2

take off

Take off your clothes carefully, but if the burns are serious and the skin adheres to the clothes, you can cut and peel the clothes carefully with scissors, keep the adhered skin, and be careful not to burst the blisters.

three

bubble

If the pain is obvious, you can soak it in cold water 15 minutes or so, but pay attention to the water temperature to avoid catching cold.

four

cover

Gently cover the wound with clean gauze, towel, cotton cloth, etc. And be careful not to burst the blisters.

five

doctor

Unless the slight redness and swelling can be treated by itself, the injured person should be sent to the hospital for further treatment.

However, the safest "cold treasure" is still

Put on more clothes and cover with quilts.

May everyone warm the winter.
