I will share interesting stories and experiences in my life with you from time to time, and exchange teaching experiences with you.
Background. In recent years, due to the improvement of people's living conditions and the convenience of transportation, many people have made winter the first choice of southerners. The snow and ice of the North are a magical and alluring thing for those in the south, who want to experience the cold weather, enjoy the spectacular snow, and have a snowball fight in the snow. However, since the "small potatoes of the south" are more and more fond of playing in the snow, in the winter there are more and more patients suffering from frostbite. In the condition of severe chilblains, it can cause limb disability and bring unimaginable pain to the patient. Burn and wound repair experts from the Guangzhou Red Cross Hospital issued a warning to raise awareness of the prevention and treatment of chilblains.
Xiao Feng's experience with chilblains.
In recent days, there has been an increasing influx of winter chilblain patients into hospitals. Among these incidents, the Xiao Feng incident has attracted much attention. Xiao Feng was once soaked in cold water for more than 30 minutes in a low temperature environment of -20 degrees Celsius in an accident, causing chilblains on his index finger. The fingers are red and black, and they have limited mobility and mobility. Through careful diagnosis and treatment, it was found that Xiao Feng's middle and distal segments had a high degree of necrosis, so it was necessary to remove the distal knuckles. There are many similar examples, and it is not uncommon for limbs to be amputated due to frostbite.
Xiaomei's chilblain experience.
Xiaomei, like Xiao Feng, is a chilblain patient. Braving the bitter cold of -15 degrees Celsius, she climbed the 5,276-meter-high peak and stayed at the summit for about 12 hours. Coming down from the mountain, she felt a little cold on her toes, as if something was missing. In the bathroom, she saw that both of her toes were blue, which scared her. She immediately applied a layer of cream to the **, then wiped her feet and went to the hospital. After being examined by the doctor, it was found that Xiaomei had severe chilblains on both feet and had the possibility of being removed.
Manifestations of chilblains are related to**.
The manifestations of chilblains are often not negligible. Li Xiaojian, a surgeon, said that in the early stage of frostbite, there will be chills, tingling, numbness and other phenomena. When chilblains worsen, they harden or harden. Mild frostbite can cause transient skin damage and requires immediate**. Severe chilblains can cause permanent loss of function and require specialized treatment.
In the event of chilblains, the following emergency measures should be taken:
1.Rapid rewarming: Immediately soak the affected area in hot water at 39-40 degrees Celsius for 15-30 minutes, and try not to contact with other heating sources (such as open flames, electric heaters, etc.) to prevent burns.
2.Passive resuscitation: move the affected limb to a warmer place, and use the body temperature near the patient or caregiver to restore the body temperature, so as to achieve the goal of slowly restoring the body temperature.
3.Lifting of the contralateral limb: Raising the affected limb above the center can reduce limb swelling.
Once chilblains occur, or the redness, swelling and pain worsen, there will be blisters, blood blisters, and bruising of the complexion. Frostbite is a disease in the burn department, and it is recommended to go to the burn department to see a doctor.
How to prevent frostbite.
Chilblains can be prevented, and Zhang Zhi taught the following methods to prevent chilblains:
1.On cold, wet or windy days, keep the frequency of going out as short as possible, and pay attention to weather reports and cold air index.
2.Pack comfortable, warm clothing, preferably a windproof and waterproof jacket, and warm underwear that absorbs moisture.
3. Wrap your ears with a hood or bandana, and use a thicker wool or windshield.
4.Wear mittens instead of gloves with interfingers, or insert the inner wall of a thin glove filled with polypropylene inside a mitten.
5.Choose suitable, absorbent, warm socks and midsoles, and try wearing platform shoes or pairing them with warm insoles.
6. Outdoor sports should be carried out continuously, and do not stand in place for too long.
7. Pay attention to keep your body dry and try not to let your clothes get wet.
8.In daily life, it is necessary to choose foods that are high in energy, high in protein and rich in vitamins to improve the body's energy and enhance the body's resistance.
9. Pay attention to timely hydration to avoid water shortage.
Usually pay attention to foot hygiene, and do frequent foot examinations to ensure the health of feet.
On this basis, the corresponding protection can greatly reduce the damage rate. Frostbite can be avoided, so I want everyone to be aware of this and have a good winter.
