After the palm of the foot is injured by the nail, should promptly seek medical treatment for local debridement as well as tetanus antitoxin injection. 1. Local debridement: rinse the wound with saline externally, expand the wound area for deeper wounds, and thoroughly rinse the dust, impurities and rust inside the wound to avoid frequent local infections. For deeper wounds, apply hydrogen peroxide and saline to rinse thoroughly to kill anaerobic bacteria, and finally disinfect with iodophor, place drainage strips, bandage, and change medicine regularly. 2. Injection of tetanus antitoxin: deeper wounds or on nails may carry Clostridium tetani, which can easily lead to tetanus infection. Anaerobic environment is the best place for Clostridium tetani to grow, thus causing tetanus infection and life-threatening injuries. Therefore, tetanus antitoxin should be injected promptly to prevent tetanus. If your foot is injured by a nail, it is important to consult a specialist to disinfect the wound and inject tetanus antitoxin.
