There was a family member of a patient who had a wound on the little toe of the right foot of an elderly person. The hospital had been using anti-inflammatory water to smear the medicine, and after about a week the whole toe was black. They wanted to know why the medicine had no effect at all. What kind of medicine can make the old man heal quickly? In fact, this old man’s case belongs to dry gangrene, which is the type of arteriopathy usually combined with lower limb arteriopathy, and is one of the more difficult ways to treat diabetic foot. In this case, the use of drugs alone is not possible, and must be integrated treatment to heal. Usually we use a combination of Chinese and Western medicine to treat this condition. Western medicine treatment includes, for example, improving circulation in the lower extremity, which is conducive to increasing the oxygen saturation of the lower extremity and supplying nutrients and drugs to the wound. One more, is the debridement, if only superficial necrosis only need to clean the necrotic skin or muscle on the line; if the toe bone necrosis and can not recover, then also need to clean. Remember, the healthy tissue must not be cleaned up, otherwise there will be more tissue infection. It is also important not to clear the wound too early, but to wait until the circulation in the lower extremity has improved. In addition, Western medicine should lower blood sugar, control blood pressure and lipids, treat cardiovascular and renal diseases, etc. The medicine should be taken and infused, and the main effort should be made to improve the overall physical condition of the patient. Then it is about the treatment of Chinese medicine, we are talking about Chinese medicine, mainly for the treatment of local wounds, the method is to use Chinese medicine creams applied externally on the wound wound after debridement, the purpose is to remove corruption and toxicity, simmering pus and muscle, change the local wound microenvironment, improve the immunity and resistance of the wound, so as to achieve the purpose of rapid healing. I would also like to raise a warning here, many people at present, although only a toe infection is often more amputations, I hope we pay attention to not blind surgery, because this is excessive treatment, and there is a possibility of re-infection after surgery. There is also, also do not do bone removal surgery, this surgery is currently carried out more, the purpose of surgery is mainly to improve circulation to treat. But in fact, the improvement of circulation is minimal, and many patients have a tragic ending.
