Wounds in diabetic patients are completely sterilized with povidone-iodine, and after the povidone-iodine has been sterilized, a topical bandage is applied. If the patient’s wound is large and clean, you can also add fibroblast growth factor locally to help the wound, heal in a relatively quick time. In addition, diabetic patients wound healing time, and blood sugar is very close to the relationship. If the diabetic’s blood sugar is well controlled, the wound heals faster. If the diabetic patient’s blood sugar is relatively high, insulin treatment should be used as soon as possible, after the appropriate drop in blood sugar, the speed of wound healing will be significantly accelerated, at the same time, insulin also has the role of promoting wound healing.
