The whitening of the surface of the abrasion wound may be caused by the exposure of fascia, exposure of periosteum, infection, too tight bandage, etc., and the cause should be identified by timely consultation. 1. Fascial exposure: If the patient’s abrasion wound is shallow, it may lead to fascial exposure, and the subcutaneous fascia has no blood vessels, so the surface of the abrasion wound will turn white, which can be treated with medication under the guidance of the doctor, and pay attention to keep the wound dry. 2. Periosteal exposure: If the patient’s abrasion wound is deeper, the bone may be injured, so that the periosteum is exposed, the wound turns white, you should go to the hospital in time, ask the doctor to carry out the appropriate surgical treatment, and intravenous cefazolin, ciprofloxacin antibiotics to prevent and control infections and other treatments. 3. Infection: If the patient’s abrasion wound is not treated in time and infection occurs, there is purulent secretion on the surface of the wound, which will also lead to the whitening of the surface of the wound, you should go to the hospital immediately, ask the doctor to clean the wound and change the dressing, and take amoxicillin, cephalexin and other antibiotics to fight the infection treatment. 4. Tight bandage: If the patient’s abrasion wound is too tightly bandaged, the blood circulation will be impeded, resulting in the emergence of the wound surface whitening, usually after the release of the bandage, the wound surface whitening will be relieved. The surface of the abrasion wound turns white, need to go to the hospital in time, follow the doctor’s instructions for treatment.
