How can we save Zhen Huan from frostbite, which even she cannot escape?

"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.

What is the cause of frostbite? Frostbite is a localized, congestive, inflammatory disease of the skin in the extremities that occurs in cold seasons. It has a slow course and heals itself after the weather warms up, but is prone to recurrence in winter.

Fingers, backs of hands, ears, and nose tips are all prone to frostbite due to poor blood circulation.

02
What are the treatments for frostbite? I believe many friends are "tormented" by frostbite every winter. The area with a history of frostbite is red, swollen, itchy and painful. The area with a history of frostbite is always in a state of "frightened bird", and it is easy to flare up at the slightest disturbance.

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.
