In the past few days, the number of frostbite patients admitted to Beijing Jishuitan Hospital has increased, most of whom have frostbite on their ears and hands. Most of the injured patients have long outdoor stays, such as riding electric vehicles and outdoor work, and some children have frostbite in their ears after only playing outdoors for dozens of minutes.
Frostbite is an injury caused by cold temperatures, and the lower the temperature, the wetter the locality, and the stronger the wind, the more severe the damage.
Wang Cheng, chief physician of the burn department of Beijing Jishuitan Hospital: The main cause of frostbite is that you don't do a good job of keeping warm when you go out. In the early stage of frostbite patients, there will be pain, numbness, swelling, severe blisters, and even the kind of black necrosis.
In cold weather, pay attention to protect the ears, nose, hands, feet and other peripheral parts, and avoid prolonged exposure in cold environments. Humid conditions are more likely to cause frostbite on tissues, so it is necessary to change clothes in time after exercising and sweating. Doctors pointed out that the "dirt method" of scrubbing frostbite with snow water is unscientific, which can aggravate tissue damage. If you notice frostbite, get out of the cold as soon as possible.
Wang Cheng, chief physician of the Burn Department of Beijing Jishuitan Hospital: The most urgent thing in the early days is rapid rewarming. Use warm water, generally 40 to 42 degrees Celsius, for example, if our hands are frozen, soak our hands in warm water, soak them for about half an hour, until their hands are red and soft and moist.
If the limb is frostbitten, avoid pressure and elevate to reduce edema. If redness, swelling and pain worsen, or symptoms such as blisters, blood blisters, and bluish skin color, you need to seek medical attention in time.
