Why must amputation be performed after severe frostbite?

Frostbite is a common symptom in daily life. If frostbite is particularly serious, amputation is necessary. This is because it is impossible to restore the original vitality of frostbitten skin or tissue through proper treatment, which is likely to cause other healthy tissues to be infected by frostbitten tissue and make the symptoms more serious.

Some people who live in cold areas or work in cold areas are likely to get frostbite, but if the frostbite is already very serious, they need to be amputated. But many patients don't understand why they have to amputate after frostbite, and can't the tissue recover? Today, with this question, let's learn why amputation is needed after frostbite.

Let's look at frostbite first. Frostbite is divided into two categories, non-frostbite and frostbite. Non-freezing frostbite is a slight frostbite of hands and ears in daily life in winter, which is generally below 10 degree. The situation is not serious, and only timely treatment can improve it, but if it is not treated in time, it may lead to tissue necrosis and aggravate the condition. The other is chilblain, which is caused by the temperature reaching below freezing point. This kind of frostbite is very harmful to people, and the tissue in the frostbite area is necrotic quickly, so it is difficult to cure after frostbite removal. In this case, amputation is a necessary treatment.

Next, I will explain in detail why amputation is needed after frostbite. First of all, the division of frostbite in medicine is very strict. Amputation will only be considered if severe frostbite is reached. The reason of amputation is that severe frostbite has caused neuromuscular necrosis, and the necrotic tissue cannot be reactivated by rewarming treatment or some treatment methods. Secondly, the necrotic part is easy to infect other healthy parts. If amputation is not carried out, it will easily spread to the whole body and threaten the life of patients. Although amputation is unacceptable to many people, it is the best and most effective method to treat severe frostbite.

Frostbite is not easy to amputate, and it needs detailed diagnosis to determine whether amputation is used for treatment. In daily life, we should also pay attention to the cold protection of the body, so as to avoid frostbite. If frostbite occurs, it must be rewarming in time to prevent tissue necrosis caused by frostbite.
