According to the Hangzhou Meteorological Observatory, Hangzhou will be controlled by dry and cold air for a considerable period of time. This week, Hangzhou will usher in a minimum temperature of about minus 5, setting a new low temperature after the beginning of winter.
Under the severe cold, everyone took out their own heating artifacts: hot water bottles, warm babies, heaters, ......
Recently, many people have been "gentle" by these seemingly "gentle" heating artifacts.
On this day, Ms. Wu (pseudonym) woke up in the morning and suddenly found that there was a big blister on her finger, and her whole hand was red, swollen and tingling.
After understanding the situation, Deputy Director Bu Zhangyu figured out the ins and outs of the blisters. It turned out that it was cold recently, and Ms. Wu always fell asleep with a hot water bottle, and the culprit of all this was this ordinary hot water bottle!
"I didn't use a very hot water bottle, why did I get blistered?”Ms. Wu was puzzled, and in the end, she was diagnosed with "low-temperature burns".
Don't look at the hot water bottle is inconspicuous, but it can burn people mercilessly. Bu Zhangyu said that in winter, the outpatient clinic will receive a lot of patients with low temperature burns, and almost every day there are several patients who are burned because of greed for warmth.
The consequences of being hurt by a heating artifact are not just blisters. Recently, 23-year-old Miss Fu (pseudonym) came to the ** venereal disease clinic with a sad face. A few days ago, she suddenly noticed that a net-like pattern had grown on her calf, like snakeskin, which could not be washed off. As a result, Miss Fu was also told that this was caused by being too greedy for warmth.
It turned out that Miss Fu, who was afraid of the cold, had placed a heater under the desk to "dry her feet" since it was cold, and over time, her calf was burned by low temperature, and Bu Zhangyu, who received the consultation, told her that it would take at least half a year to a year for this pattern to heal itself.
Bu Zhangyu introduced that such a pattern-like burn, clinically known as "fire erythema", after a long period of exposure to high temperatures, **telangiectasia and congestion, over time will lead to pigmentation. "In general, the fire irritationous erythema that comes into contact with it is related to the heater, which is purple-black, reticulated, and looks like marble. Bu Zhangyu said that the erythema is almost painless, mainly because it will affect the aesthetics, and it takes six months to a year to recover.
The biggest puzzle for most patients who are scalded at low temperature is that they don't feel burned, so why are they burned?
Bu Zhangyu said, ** is actually very delicate, as long as the temperature exceeds the body temperature of 37 for a long time, it may cause harm to **. Burns caused by low-temperature stimuli are all "low-temperature burns". And everyone thinks that the temperature of the hot water bottle and heater that is "not hot" is above 50 degrees, and as long as the contact is long enough, it may be gently burned.
Bu Zhangyu reminded that low-temperature burns are more common in people with low pain sensation, such as: paralyzed patients, because they can't turn over, they are not suitable for long-term electric blankets;Diabetic patients, vasculitis and other patients, especially patients with peripheral neuropathy, ** nerve sensation dullness and numbness, are also not suitable;Due to the delicate nature of children, the sensitivity to heat and pain decreases when they fall asleep, and they are also prone to low-temperature burns.
There are a few simple ways to avoid being burned by low temperatures. The water temperature of the hot water bottle should not be too hot, and it is best to put on a "coat" for the hot water bottle;Try not to use heating items overnight, and turn off the power in time after the electric blanket**When using a heater, avoid direct radiation and direct blowing, **If there is a hot feeling, it means that the distance is too close, and there is a risk of being scalded by low temperature.
