Warm baby, electric blanket, hot water bottle, electric hand warmer ......In the cold winter, southerners who rely on shaking for heating are all too familiar with these "heating artifacts".
In daily life, it is not uncommon for boiling water, open flames and other high temperatures to cause burns, but many people do not know that heating equipment such as hot water bottles, electric blankets, and small suns can cause low-temperature burns through direct contact or irradiation.
Some time ago, with the sudden drop in temperature, the number of low-temperature scald cases admitted to major hospitals in Changsha increased significantly, and some severe scald cases even required surgery**. Experts remind that daily heating should be avoided for a long time and in the same part, do not ignore the possible harm caused by low-temperature burns, and seek medical treatment in time for deep wounds.
After sticking it for 5 hours to warm the baby, his calf ** pulled painfully.
17-year-old Xiao Li is preparing for the college entrance examination and sits at his desk for a long time every day to review his homework. Recently, in order to keep out the cold, he put the warm baby directly on the calf**. Because he was too focused, he forgot about the four warm babies that he was sticking to, and it wasn't until he put down the book 5 hours later and planned to move that he felt some pulling pain in his calf**. He took off the warm baby to check and found that the calf ** had been red, although he immediately applied the scalding cream, the next day there were symptoms such as redness, swelling, blisters, dry pain, etc., and he could only go to the hospital**.
Ms. Lin had a similar experience. Some time ago, Ms. Lin was hospitalized due to an internal medical illness**, and her family was worried about the cold night, so they put the filled hot water bottle in Ms. Lin's quilt. Throughout the night, Ms. Lin's calf was attached to the hot water bottle, and the next morning, when her daughter moved the hot water bottle, she found that Ms. Lin's calf ** was red. Soon, Ms. Lin** developed dry pain, blisters, and then formed a wound that did not heal for a long time. Eventually, she had to be transferred to the burn surgery department**.
Theoretically, temperatures above 45 can cause harm to the human body, such as warm babies and hot water bottles, although the temperature is relatively low, they are above the injury threshold, and they may also cause serious burns after long-term contact. Su Ximei, chief of plastic and cosmetic burn surgery and chief nurse of the Second Xiangya Hospital of Central South University, said that generally speaking, the temperature of the human body is about 37, and when the heat source is higher than the temperature of the human body and acts for a long time, it may lead to damage to the soft tissue from shallow to deep.
According to reports, among the people who come to the hospital for low-temperature scalds, the most common are the elderly, children, diabetics, etc. "This is due to the fact that the elderly have a dull sensation in the lower limbs, and the scald is not easy to perceive until the burn is severe. Children are also prone to low-temperature burns because of factors such as delicate and poor expression ability. Su Ximei reminded that diabetic patients are also at high risk of low-temperature scalding due to insensitivity to peripheral neuropathy nerve endings, and disabled people are also at high risk of low-temperature scalding due to local sensory dysfunction or reduced sensitivity to thermal stimuli.
Students and working people, although they do not belong to the group of people who are prone to low-temperature burns, but when they are in a deep sleep and drunken state at night, because the temperature is not too high, they can also be burned by low-temperature if they continue to act on the same part for a long time.
Low-temperature scalds are like "boiling frogs in warm water".
In fact, low-temperature scalding is the same as 'boiling a frog in warm water'. Su Ximei explained that pain is an important protective mechanism of the human body, when the human body is in contact with boiling water, open flame and other high temperatures, it is equivalent to a strong stimulus, and the sensory nerve endings can quickly conduct this stimulation to the human brain, resulting in pain, and the brain will guide the human body to quickly avoid.
When in contact with a temperature of 45 to 50, such as using heating equipment such as hot water bottles, baby warmers, fan heaters, electric blankets, etc., the sensory nerve endings will not immediately feel the stimulation, but will adapt to the contact with the temperature after a long period of contact, so it will not cause pain sensing and brain perception, and will not immediately feel the pain of burns. However, when the surface tissue is gradually dehydrated under the action of heat energy, and the heat dissipation is not smooth under the action of pressure, which eventually leads to deep tissue burns. In the cold winter, the sensory nerve endings of the human body are more sluggish, and it is more likely to cause low-temperature burns.
The warm baby can not be directly attached to the **, it should be pasted through clothes.
In the cold winter, it is best not to use heating items without direct contact with the body, and it is best not to use heating items on the same part for no more than 30 minutes. In particular, diabetic patients, paralyzed patients, the elderly, infants and young children, and people with distal limb blood vascularization disorders are not suitable for long-term use of heating items in the same area.
Su Ximei introduced that the warm baby can not be directly pasted on the **, but should be pasted through the clothes, and the time should not be too long, so as not to burn;Hot water bottles and hand warmers should be covered with a protective cover before use, and it is best to change the position every 30 minutesUse an electric blanket, don't be on for too long, ** When you fall asleep, you should turn off the power and avoid using it all night, it is best to use an electric blanket with temperature control, which can be adjusted to the heat preservation gear when the temperature is appropriateThe hot water bottle should not be filled too full, fill about 70% hot water, the water temperature should not be too hot, and you can wrap the hot water bottle with a towel when you put it under your feet to warm up, and do not make the hot surface act directly on the **;When the hand warmer is powered on, do not hold it in your arms, do not directly contact **, you can put on a protective cover, and at the same time pay attention to the temperature is not too high, do not beat, sit on pressure, and stab the hand warmer with a sharp object, so as not to cause leakage.
In addition, cupping and moxibustion must pay attention to the protection of **, the temperature of the cupping mouth should not be too high, and the duration of moxibustion should be controlled.
There is a low temperature burn, what should I do?If the burn is mild, a burn cream can be applied while promoting blood circulation by elevating the affected area, reducing symptoms of swelling and pain. If the symptoms are severe, with large blisters or ulcers, you should seek medical attention immediately to avoid further deterioration of the wound.

1.Before using any heating device, read the instructions for use carefully to understand its operating temperature and recommended use time.
2.Avoid direct contact with heating equipment during sleep, and if needed, add an additional layer of isolation between the device and **.
3.For equipment that needs to be heated for long periods of time, choose a product with an automatic shut-off function to reduce the risk of overheating.
4.Check the ** reaction regularly (it is recommended that the time interval should not exceed 30 minutes), especially in the parts where the heating equipment is in contact, and the position should be adjusted in time or the use should be stopped.
5.For people who are insensitive, family members or caregivers should be aware of their use of heating equipment.
