Wounds in diabetic patients can be completely disinfected with iodophor, and after disinfection with iodophor, local dressing is applied. If the patient’s wound is relatively large and clean, fibroblast growth factor can be added locally to help the wound heal in a relatively short period of time. In addition, the wound healing time for diabetic patients is very closely related to blood sugar. If the diabetic patient’s blood sugar is well controlled, the wound will heal faster. If the blood sugar of diabetic patients is high, they should be treated with insulin as soon as possible. After the blood sugar drops properly, the wound healing speed will be significantly accelerated, and at the same time, insulin also has the effect of promoting wound healing.
