Amputation is the surgical removal of part or all of a limb, and after the operation, attention should be paid to the relevant nursing work to avoid infection. 1. In clinic, it is usually caused by poor blood circulation due to arterial damage or narrowing, if there is not enough blood flow, it will lead to the cells of the body not being able to get the necessary oxygen and nutrients from the blood, which will lead to necrosis of the tissues, and may lead to infections. Amputation is often required for injuries sustained in traffic accidents, severe burns, frostbite, and cancerous tumors in the bones or muscles of the limb. 2. General or local anesthesia is often required under a doctor’s supervision before amputation surgery. During the surgery, the surgeon will remove the diseased tissues and all the broken bones, smooth the uneven parts of the bones, close the blood vessels and nerves, and cut and shape the muscles to fit the prosthesis later. 3. After the amputation surgery, it is necessary to pay attention to the care of local wounds to avoid infection. At the same time, it is necessary to improve the strength and control of the residual limb muscles through exercise, which will help to restore daily movement. After full recovery, you can wear a prosthesis for functional exercise. Amputation requires early preparation of the mind, spirit and body. Detailed preparations can be made by consulting the surgeon.
