10-year-old child scalded while sleeping with hot water bottle

A few days ago, 10-year-old Ran Ran (pseudonym) woke up in the morning and suddenly found a blister on his leg. He was so scared that he quickly picked it with his hands and finally broke the blister . Unexpectedly, two days later, the place became red and painful ... Ran Ran's mother immediately took him to the dermatology department of the hospital for treatment.

Blisters on Ranran's legs

The doctor saw the redness and swelling on Ranran's legs and immediately found the cause - low temperature burns . It turned out that the weather was getting cold, and Ranran's mother would fill a hot water bottle for Ranran every night before going to bed. When sleeping, Ranran clamped the hot water bottle between his thighs , and after a night of being burned by the hot water bottle.

"Don't think that the hot water bottle is not very hot. It will burn you mercilessly." The doctor explained that in winter, the skin's sense of the external temperature will become dull, especially when you are in deep sleep, the skin is even less sensitive to the external temperature . If you keep the hot water bottle in the same position for a long time, it is easy to get blisters and cause low-temperature burns.

Doctors remind that once blisters form, never break them, as blister fluid is an excellent bacterial culture fluid and infection can easily occur once they break.

What is a low temperature burn?

Low-temperature burns refer to chronic burns caused by prolonged contact of a part of the body with a low-temperature object of 41°C to 45°C .

Generally speaking, short-term contact between the skin and low-temperature heat source will only cause blister-type burns in the superficial dermis, but if the low-temperature heat source continues to act, it will gradually develop into burns in the deep dermis and subcutaneous tissues.

Unlike burns caused by high temperature, the pain of "low-temperature burns" is not very obvious. Only redness, swelling, blisters, peeling or whitening will appear on the surface of the skin , and the area is not large. However, in severe cases, it will cause deep tissue necrosis . If not handled properly, ulceration will occur, causing the wound to be unable to heal for a long time.

Women: Cold hands and feet are more common in winter than men, so they use more heating tools.

Patients after anesthesia and drunk people are also prone to low-temperature burns due to unclear consciousness.

People who are frozen to the point of numbness in their hands and feet outdoors and immediately go indoors to warm themselves up .
