Follow me and I will share some interesting stories and experiences on a regular basis to exchange educational experiences together.
Foreword: This winter, the snow and ice scenery in the Northeast has attracted the attention of many southerners, who have gone to experience the fun in the snow. However, while playing in the snow, you should also be careful to prevent frostbite from occurring. Recently, the Department of Burns and Wound Repair of Guangzhou Red Cross Hospital admitted a patient with frostbite to his hands, which aroused people's attention to frostbite. Doctors remind that in cold weather, we should know about the prevention and treatment of frostbite in advance to protect our health.
Frostbite is caused by low temperatures** and tissue damage, and severe frostbite can even lead to amputation. Xiao Feng (pseudonym), who was recently admitted to the Burn and Wound Repair Department of Guangzhou Red Cross Hospital, is a typical case of frostbite. Xiao Feng was trapped in the cold storage of -20 for 30 minutes in an accident, resulting in frostbite to varying degrees on his hands and ears. When he was admitted to the hospital, Xiao Feng's fingers were red, swollen and black, and he had undergone a partial osteotomy. This sad case reminds us once again that frostbite is a serious injury that we must take seriously.
Expanding: Frostbite is a common but devastating injury, and in severe cold weather, our ** is easily attacked by low temperatures. When we are exposed to cold, blood vessels constrict and blood flow decreases, which affects the blood supply and oxygen to tissues. When exposed to low temperatures for a long time, tissue cells will be frozen and damaged, resulting in whitening, pain, and in severe cases, symptoms such as tissue necrosis and ulceration. Frostbite not only affects the function of the injured area, but can also lead to infections and complications, and even amputation. Therefore, it is very important to prevent and treat frostbite in a timely manner.
Due to the warm climate in the south, southerners are relatively weak in their ability to adapt to low temperatures and are more susceptible to frostbite. Recently, the Department of Burns and Plastic Surgery of the Guangzhou Red Cross Hospital also admitted Xiaomei (pseudonym), a patient with frostbite on both feet. While pursuing her passion for snow, Mei unfortunately stayed on the mountain peak at minus 15 degrees Celsius for about 12 hours. When she returned to Guangzhou, she found that her feet were cold and missing, and her toes were purple. This is a typical symptom of frostbite, and she immediately sought medical attention and received the corresponding **.
Expansion: Southerners are often unexposed to cold climates and are relatively weak in adapting to low temperatures. When they arrive in cold areas and engage in snow activities, they are prone to maladaptation. Due to a lack of knowledge about frostbite, they may not be able to detect the first symptoms of frostbite in time, leading to exacerbations. At the same time, southerners are usually more delicate and more susceptible to low-temperature environments. Therefore, southern tourists need to pay special attention to protect their bodies and prevent frostbite when playing in the snow.
Understanding the symptoms of frostbite is key to prevention and treatment. Zhang Zhi, director of the Department of Burns and Wound Repair at Guangzhou Red Cross Hospital, reminded that the symptoms of frostbite can be divided into several stages. First is chills and tingling, followed by numbness and**inflammation or discoloration. As the condition worsens, it may harden or wax. Frostbite is more likely to occur on the dorsum of the hands and feet, heels, fingers, pinna and the tip of the nose, etc., and the redness or pain in any ** part is a sign that frostbite may have begun.
Expansion: The symptoms of frostbite are diverse, and different patients may present with different symptoms. In cold weather, we should always pay attention to the changes, especially the exposed parts. When we feel chills, tingling, and obvious redness, swelling and pain, we should be alert, it may be that frostbite has already begun. At this time, we should immediately stay away from the cold environment, or take protective measures against the injured **. Any red, painful area may be a sign of frostbite and should be treated promptly.
For the emergency treatment of frostbite, Director Li Xiaojian reminded everyone to remember the "three wants and three don'ts". First of all, get into a warm room as soon as possible to avoid further cold. Secondly, the frostbitten area should be soaked in warm water (39 -40) to restore local blood circulation. Body temperature can also be used to warm the frostbitten area, such as the frostbitten fingers under the armpits. Finally, pay attention to three don'ts, that is, do not walk with frostbitten feet, do not rub frostbitten areas with ice and snow, and do not use heating equipment such as electric blankets, baking lamps, stoves, and electric heaters to avoid further damage.
Expanding: When we find ourselves with frostbite, we should take emergency measures in time. First of all, it is necessary to quickly leave the cold environment and go into a warm room to avoid further cold. Secondly, you can soak the frostbitten area with warm water, and the temperature is recommended to be between 39 -40, which can restore blood circulation and speed up the wound. In addition, we can also use our own body temperature to warm the frostbitten area, such as putting the frostbitten fingers under the armpits to keep warm. At the same time, we should pay attention to avoid the following three aspects: do not continue to walk with frostbitten feet, so as not to increase the damage; Do not rub the frostbite area with ice and snow, as this will aggravate tissue damage and cause blood clots; Do not use heating equipment such as electric blankets, baking lamps, stoves, electric heaters, etc., to avoid further damage caused by overheating. In addition, it is important to keep warm and wear dry and warm clothing to prevent colds and hypothermia.
Prevention of frostbite is paramount. In cold weather, we should pay attention to the following three aspects to prevent frostbite. First of all, keep plenty of clothing and wear well-layered clothing so that you can adjust to the temperature. Secondly, you should pay attention to keeping warm, especially the hands, feet, head and face and other parts that are prone to cold, and you can equip warm gloves, hats, towels and other items. Finally, avoid prolonged exposure to the cold, minimize time spent outdoors, and wear appropriate footwear and clothing if you must go outside.
Expansion: Prevention of frostbite is the most effective method. In a cryogenic environment, we should do the following to protect ourselves. First of all, it is important to be careful to wear enough clothing, which can be layered so that you can adjust to the temperature. Secondly, special attention should be paid to protecting areas that are prone to cold, such as hands, feet, head and face, and warm gloves, hats, scarves and other items can be equipped. Finally, avoid prolonged exposure to the cold, minimize outdoor activities, and choose appropriate footwear and clothing if you must go out to reduce exposure to cold winds.
It is very important for people suffering from frostbite to seek medical attention promptly. Li Xiaojian, director of the burn and wound repair department at the Guangzhou Red Cross Hospital, stressed that the condition of frostbite may worsen in a short period of time, so it is necessary to seek medical attention in time. For mild frostbite, symptoms can be relieved by soaking in warm water and keeping warm. However, severe frostbite may require surgery** or professional wound repair. In addition, frostbite is also prone to infections and complications, so it is important to pay close attention to changes in the wound and seek medical attention if there is any abnormality.
Expanding: It is very important for people with frostbite to seek medical attention promptly. Frostbite can worsen quickly, so seek medical help as soon as possible. For mild frostbite, we can relieve the symptoms by soaking in warm water and keeping warm. However, severe frostbite may require surgery** or professional wound repair. Frostbite can also lead to infections and complications, so keep an eye on the wound and seek medical attention if there is any abnormality. At the same time, we should also pay attention to our own health, try to avoid cold environments, pay attention to warmth and cold protection, and prevent the occurrence of frostbite.
