An old man from Jilin, with a history of diabetes for nearly 30 years and poor eyesight, once trimmed his toenail and accidentally cut his big toenail, which was painful but not bleeding, and did not care. However, within a few days, the wound became painful and infected, and half of the foot ulcerated and flowed pus. The local endocrinologist said that this is a diabetic foot, and if it does not progress, there is a high risk of amputation. What should I do to treat this situation? Why would a pedicure lead to a rotten foot? In fact, this is one of the characteristics of diabetic foot. Patients are subjected to long-term high blood sugar eating, they will develop lesions, most commonly peripheral neuropathy and peripheral vascular lesions in the lower limbs. Peripheral neuropathy tends to lead to decreased sensory sensitivity in the lower limbs, and it is not easy to feel pain when trimming the feet, and wounds are not perceived, which often leads to deeper wounds. Vascular lesions tend to lead to impaired blood supply to the lower extremities, and the wound is unable to transport nutrients and medications in a timely and effective manner, resulting in a lack of wound healing and an increased risk of infection. In addition, many patients with long duration of disease, older patients, patients with hypertension, dyslipidemia, bedridden patients with mobility problems, patients with cardiovascular and cerebrovascular and sequelae, etc., these people have difficulty in healing their own wounds or even do not heal, the risk of infection is great, trimming should be more careful. So, how can an already infected wound be treated? I believe there are many patients who have had the experience of having a wound that has been treated in the hospital, using methods that are often insulin to control infection, surface sterilization, antibiotics to control infection these three things, which often lead to aggravation of the patient’s wound. Why does this happen? Because the treatment is not right. Inflammatory necrotic tissue is already present locally in the wound, and if the wound is not cleaned, the large amount of germs multiplying and metabolizing in the inflammatory tissue affects the vitality of the local cells and only erodes more healthy tissue and produces more pus. However, the idea of diabetic foot treatment is really simple, as long as the comprehensive treatment of local wounds such as debridement, infection control, improvement of circulation, nutrition of the wound surface and debridement and muscle growth is done on the basis of systemic comprehensive treatment, especially Chinese herbal cream creates a wet environment for the wound, the wound can really achieve natural healing. However, the key is also to take care of each and every aspect to achieve better results. So when you encounter problems, you must go to a regular department or hospital with experience in treating diabetic foot to avoid aggravating the wound with improper treatment.
