A nail stuck in the foot should be promptly visited to the hospital, and the foreign body should be pulled out by a professional doctor. At the same time, the wound should also be further cleaned, applying saline and hydrogen peroxide to repeatedly flush the wound, and for deeper wounds should be further cleared under local anesthesia. Because tetanus is easily complicated by trauma, especially by nails containing rust, the wound should be treated thoroughly and a refined tetanus antitoxin injection should be given within 24 hours of injury. In the postoperative period, anti-infection treatment should be actively carried out. Mild patients can take oral roxithromycin dispersible tablets, or intravenous penicillin sodium if necessary, and attention should be paid to regular drug changes. If the location is deep, local x-ray examination is also required if necessary.
