The primary management of a diabetic patient who develops an ulcer on the skin should be intensive glycemic control with insulin, because we know that having adequate glycemic control also promotes healing of the ulcerated surface. In addition, insulin itself contributes to the healing effect of the wound, so insulin hypoglycemic therapy should be placed at the top of the list. In diabetic patients with localized ulcers combined with infection, strong antibiotics should be given for systemic anti-infective therapy. The localized skin ulcers should be treated with intensive dressing changes, and the dressing should be changed regularly after the localized surgical removal of necrotic tissues. In addition, silver ion dressing can be used externally or because of the growth of drugs, can promote wound healing. If the patient is also combined with poor nutritional status and hypoproteinemia, nutritional support should be given. Transfusion of albumin will also be conducive to the healing of the ulcer surface. Then it is to strengthen the improvement of diabetic blood circulation, which is conducive to the repair and healing of the ulcer.
