Why is the mortality rate after amputation of diabetic foot high?

Before talking about mortality, it is first necessary to talk about the amputation rate of diabetic foot. Improper treatment of diabetic foot and patient treatment are not timely, resulting in high rates of amputation of diabetes. According to statistics, 70 amputation operations worldwide are related to diabetes. The amputation rate of diabetic foot patients is 25 times that of non-diabetics. Specifically, every 30 seconds in the world, a diabetic foot patient is amputated.

Why is the mortality rate after amputation of diabetic foot high?

If the amputation can cure the diabetic foot, it may be the best choice for some patients. However, according to the survey, the mortality rate of diabetic foot patients within 20 months after amputation is 20%, and the mortality rate within 5 years is even as high as 50-70%. This undoubtedly sounded the alarm for us.

In fact, the mortality rate after the amputation of diabetic foot is so high that it is foreseeable. The reasons can be analyzed from the following aspects:

1. There is no improvement in blood supply to the lower extremities. Diabetic foot is often accompanied by lower limb nerve and vascular disease, especially vascular disease, which is easy to cause blood circulation disorder in the lower limbs and insufficient blood supply. After amputation treatment, the vascular lesions of the lower extremities were not relieved, and the blood supply to the lower limbs was still insufficient, leading to further necrosis and life-threatening safety.


2. Amputation trauma initiates a blood clotting mechanism that causes thrombosis. Amputation surgery will initiate the blood clotting mechanism of the lower extremities. In the case of poor blood circulation, thrombosis is very likely to occur at this time. In addition to increasing the severity of the lower limbs, it also increases the occurrence of vascular diseases. Strokes and hemiplegia may occur. .

3. Lower extremity wounds cause infection. We all know that diabetic patients will have a situation in which the wound is not easy to heal. In addition, after the amputation, the patient's life treatment is obviously reduced, the movement is inconvenient, the body and mind are severely hit, and it is more likely to re-infect. Some patients have to undergo secondary amputation after infection, and then may cause infection. This has entered a vicious circle, and the consequences are unimaginable.

Here, I also ring an alarm for diabetic patients. Diabetic foot can be treated without amputation. The important thing is that the treatment should be correct and the treatment should be timely. However, treatment is not fundamental, and early prevention is the top priority of our work.
