What causes rotten and black feet in diabetic patients? In fact, this is one of the typical complications of diabetes, diabetic foot, according to clinical symptoms are generally divided into three types of wet gangrene, dry gangrene and mixed gangrene. Wet gangrene lower extremity blood supply is more abundant, the wound infection often shows ulcerative symptoms. Dry gangrene is usually combined with arterial vascular lesions in the lower extremities, where venous return is not a problem and the wound becomes dry and blackened and necrotic due to local dehydration and ischemia. Patients present with both ulceration and blackened necrosis, a condition known as mixed gangrene. In this case, the degree of vascular disease in the lower extremity is not particularly large, the ischemia is not too severe, and the wound is in a state of semi-dehydration. At this time, the germs continue to erode healthy tissue, and a large amount of cellular rupture tissue fluid will also exude, and the degree of wound infection is often great, and if left unchecked, the symptoms will gradually worsen. What should I do when I encounter this situation? First, one must first go to the hospital for relevant examinations to find out the patient’s specific physical condition, routine blood tests, vascular lesions, neuropathy, heart, brain, kidney and other organs, wound secretion sensitivity, and, if necessary, the presence of bone destruction, which is equally critical to the diagnosis of osteomyelitis. Second, according to the cause of the disease to develop the appropriate treatment plan. High blood sugar should be actively controlled, treatment of cardiovascular disease, electrolyte disorders should be corrected, the dialysis, and so on. Third, the control of infection. Infection control is very critical and also required. For diabetic patients with infected wounds, the most critical point is the cleaning of inflammatory tissues. Necrotic inflammatory tissue is a breeding ground for germs, countless germs are active, if only rely on antibiotics, the usual situation is a large variety of doses, just so it is also very difficult to control, and later will be out of control. Fourth, the use of Chinese ointment. Practice has proven that the use of Chinese ointment is particularly helpful for wound healing compared to various dressings. There is a clear theoretical basis for the treatment of diabetic foot in Chinese medicine, for example, “simmering pus and generating muscle” is discussed in detail in “Surgery Qixuan”. In short, if you receive the right treatment as soon as possible after the appearance of rotten feet, it will not cause serious harm to your body. On the contrary, if the treatment is not timely, or the method of thinking is not correct, then it will become more and more serious. I hope that you encounter this situation must pay attention to it, early to let patients get rid of the disease torture.
