The treatment of skin scratch wounds includes disinfection and debridement, tissue repair, infection prevention and other items, and it is recommended to dispose of them in a professional medical institution. 1. Disinfection and debridement: After a skin scratch, local disinfection is needed. For first-time wounds, disinfection can be done by using iodophor, hydrogen peroxide and other disinfectants to disinfect the wound, rinse the wound repeatedly and remove foreign objects around the wound. For relatively shallow wounds, you can use sterile gauze or band-aid bandage after regular disinfection, dressing change treatment. 2. Tissue repair: For deeper wounds, thorough debridement and disinfection of the wound is required, followed by suturing of the skin and deep tissues; if there are important vascular and nerve injuries, surgical suturing is required. Local infiltration anesthesia is usually chosen. After the operation, regular dressing change and suture removal are required. 3. Infection prevention: if the scratch is seriously contaminated by foreign objects or the wound is deep, it is recommended to receive tetanus vaccination; if the wound is pus-filled, it is necessary to take amoxicillin, cefaclor and other antibiotics for anti-infection treatment. The above drugs need to be used under the guidance of clinicians.
