Follow me and I will share some interesting stories and experiences on a regular basis to exchange educational experiences together.
Recently, the Burn and Wound Repair Department of the Guangzhou Red Cross Hospital admitted a patient named Xiao Feng. Xiao Feng was accidentally locked in a cold storage for 30 minutes in the middle of the night in a cold rural area, when the temperature reached minus 20 degrees Celsius. By the time she was found by her colleagues and rescued in time, Xiao Feng's hands and ears had been frostbitten to varying degrees. When he was sent to the hospital, Xiao Feng's hands were numb and tingling, and his fingers were red, swollen, black, and visibly blistered. In view of the dry necrosis of the distal segment of Xiao Feng's finger, the doctor could only amputate the distal phalanx. Such an innocent accident, just because of the 30-minute freeze, Xiao Feng's hands will be amputated! This makes us deeply aware that the southern little potatoes must be careful to avoid the risk of frostbite when playing in the snow.
Frostbite is a phenomenon in which human tissues are frozen when the ambient temperature is extremely low, and the severity can lead to limb necrosis and amputation. Recently, as China ushered in the first large-scale cooling of the year, the number of frostbite patients in winter is increasing. Among them, the small potatoes in the south have gone to the ice and snow world in the north to explore, but they have relatively little knowledge about frostbite, and they lack the necessary knowledge for the emergency treatment of frostbite. This makes it more necessary for the southern little potatoes to maintain a high degree of vigilance and take corresponding precautions in the process of playing in the snow to avoid permanent damage to their bodies caused by frostbite.
Playing in the snow is an exciting outdoor activity, but southern potatoes often lack the ability to adapt to cold conditions, increasing their risk of frostbite. Therefore, we need to make some necessary preparations before stepping on the snow.
First of all, it is very important to dress appropriately. Choose thick, breathable clothing and wear extra layers of warm clothing to increase your body's thermal insulation performance in low temperatures. At the same time, wear warm supplies such as hats, scarves, and gloves to minimize the exposed area to prevent direct contact with cold air.
Second, choose the right shoes. When walking in the snow, you need to choose non-slip shoes to avoid injuries due to falls. In addition, non-slip shoe covers or snow boots can be used for extra protection and stability.
Finally, be physically prepared accordingly. Playing in the snow is a physically demanding sport, especially in activities such as running in snowdrifts and having snowball fights. Therefore, it is advisable to do a moderate workout in advance to increase physical strength and endurance to better enjoy the fun of snow activities.
The symptoms of frostbite tend to vary depending on the severity of the frostbite. In general, mild frostbite can lead to transient damage, while severe frostbite can lead to permanent dysfunction or even life-threatening. Therefore, when the following symptoms appear, we should be alert to the possibility of frostbite and take emergency treatment in time.
First of all, frostbite can cause chills and tingling sensations. If you start to experience chills, tingling sensations in a certain area of the cold environment, then you may have been affected by frostbite.
Secondly, frostbite can cause ** to feel unusually hard and even take on a waxy texture. When you find that the ** paresthesia in the frozen area is abnormally hardened, stiff, and even unable to feel the touch of the outside world, it means that the degree of frostbite has worsened.
Finally, frostbite can also cause inflammation or discoloration. During the further development of frostbite, you may observe redness, inflammation, and even bluish and purple of the frozen area.
When you experience these symptoms, it's important to take prompt emergency measures. First, quickly move the frozen area to a warm indoor environment and soak it in warm water at a temperature between 39 degrees Celsius and 40 degrees Celsius. At the same time, additional warmth can be provided by touching the frostbitten area with a warm body part, such as the armpits. It should be noted that in the treatment of frostbite, the following wrong treatment methods must be avoided: do not use ice and snow to rub the frostbitten area, do not use electric blankets, baking lamps, stoves, electric heaters and other heating equipment, and do not continue to expose to cold environments. These treatments may worsen the damage to frostbitten tissue, with more serious consequences.
Finally, if the symptoms of frostbite worsen or if symptoms such as blisters, blood blisters, and bluish skin color appear, you should seek medical attention promptly**. Frostbite falls under the category of the burn department** and can be treated in the outpatient and emergency department of the burn department**. Severe frostbite may require hospitalization** or even surgery to repair the damaged**.
Playing in the snow is an exciting and enjoyable activity, but we should always be vigilant, especially the small potatoes in the south, and be extra careful about the risk of frostbite. With proper prevention and emergency treatment, we can minimize the occurrence of frostbite and protect our health. Remember the three signs of frostbite, take the right measures in time, and be alert to the danger of frostbite!
