It is recommended to go to the hospital promptly for debridement and dressing when the foot is stabbed by a nail. The trauma caused by the nail is usually narrow and deep, and the surface of the nail usually has impurities such as dust or rust, which can easily lead to tetanus in an anaerobic environment with a high rate of morbidity and mortality. Therefore, if the foot is nailed, should promptly clean the local trauma, tetanus antitoxin injection, and actively prevent infection. Specific treatment can be carried out as follows: a. Clean the local wound: 1. repeatedly open the local wound, apply hydrogen peroxide to thoroughly clean the wound; 2. rinse again with saline until the residual hydrogen peroxide is rinsed clean; 3. apply iodine volts to thoroughly disinfect the local skin of the wound. Second, injection of tetanus antitoxin: tetanus antitoxin injection within 24 hours, and change the medication on time during the recovery process to fully drain the local secretions. Third, active prevention of infection: oral antibiotics should be taken during the recovery period, such as cephalosporins, erythromycin and other drugs to prevent infection.
