"Miss's frostbite has come back again, and it seems to be more swollen this year." Friends who have watched the TV series "The Legend of Zhen Huan" must be familiar with this scene: Zhen Huan gave up her position as a concubine out of hatred and went to Ganlu Temple to practice. She washed the quilt with cold water in the cold winter and got frostbite on her hands. Thereafter, every winter, even though Huanhuan returned to the warm and magnificent palace, she still couldn't avoid the pain. 01 Fingers, backs of hands, ears, and nose tips are all prone to frostbite due to poor blood circulation. 02 In this regard, Ding Xiaolan, deputy chief physician of the Department of Dermatology and Venereology at Peking University People's Hospital, said: Once frostbite occurs, if it is not diagnosed and treated in time, it will be a disaster every winter. Therefore, you must know the following 4 methods to treat frostbite. 【Knowledge Points】 ① Keep warm The contraction of blood vessels is related to temperature. Especially for patients with a history of frostbite, they must keep warm, such as hands and ears. All exposed parts must be kept warm. ②Topical medications You can use Hirudo ointment or Centella asiatica ointment externally to improve the symptoms of frostbite; frostbite ointment can also play a therapeutic role. ③ Systemic oral medications Improve vasoconstriction, such as nifedipine. ④Physical therapy Some frostbite may develop ulcers due to repeated infection and repeated ulceration. At this time, local physical methods such as red light irradiation or semiconductor laser irradiation can be used to promote rapid healing of frostbite. 03 How to prevent frostbite? Although frostbite will heal on its own, it makes your hands red and swollen, unsightly, uncomfortable in cold weather, itchy in warm weather, and in severe cases, it may leave wounds. Therefore, we need to actively prevent frostbite in our daily lives. Keep warm, but don't wear tight shoes or socks. Change your shoes and socks frequently and keep them dry. Before the weather turns cold, insist on washing your face and hands with cold water. Massage your hands, feet, ears and other parts frequently. Wash your hands frequently and soak your feet in warm water every day. Apply protective agents such as Vaseline as a preventive measure. All in all, frostbite is not scary, the key is to keep warm! |
