The cold wave hit, and the number of frostbite patients in many places has increased in the past few days. Most of the injured patients have long outdoor stays, such as riding electric vehicles, outdoor work, and some children play outdoors, resulting in frostbite in the ears. Doctors reminded to pay attention to warm protection in cold weather, and to take the correct treatment after frostbite.
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.
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 will 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 ** in the early days was to use warm water at 40 to 42 degrees Celsius to quickly rewarm. For example, if your hands are frostbitten, soak your hands in warm water for about half an hour, and soak them until your hands become red and soft and moist.
If the limb is frostbitten, avoid pressure and elevate to reduce edema. If you have redness, swelling, worsening pain, or symptoms such as blisters, blood blisters, and bluish skin color, you need to seek medical attention in time.
