If the skin is scratched and bleeding, the first thing to do is to apply pressure to stop the bleeding and promptly send it to the hospital for thorough debridement by a professional doctor. If the wound is deep, you can apply hydrogen peroxide for rinsing to flush out the foreign body. If the residual foreign body is likely to cause infection, apply iodophor to disinfect the wound and then suture the wound. If the wound is dirty and deep, tetanus antitoxin or tetanus immunoglobulin is required. Tetanus antitoxin needs to be injected within 24 hours. In addition, after thorough debridement and suturing, medication should be changed in time to observe the healing situation and prevent infection, and oral antibiotics can be administered for anti-infection treatment.
