For diabetic patients who undergo surgical treatment, there is no special good medicine for wound healing, and they need to change the medicine more often and observe the wound more often. If there is redness, swelling and hardness in the wound, it should be treated early and promptly, and the surface of the wound can be covered with iodine povidone gauze or isacridine gauze, to isolate the external bacteria and prevent them from invading into the diabetic patient’s wounds, which may lead to wound infection. If there is fat liquefaction in the wound, usually on the third or fourth day after surgery, a few sutures can be removed intermittently to clean out the liquefied fat in the incision in time, so as to prevent the liquefied fat from accumulating for a long time in the wound and secondary bacterial infection. If the wound is already infected, the sutures should be removed completely and then changed with povidone-iodine to smooth the drainage. At the same time, for diabetic patients with wound dressing, blood glucose should be monitored in a timely manner to prevent too much fluctuation in blood glucose.
