If there is no skin wound or the wound is superficial, usually there is no need for tetanus, and it can be disinfected and cleaned up in time, if the wound is deeper, then tetanus is needed. 1. Shallow wounds: If there is no skin breakage or shallow wounds after a fall on a bicycle, there is no need to play tetanus for only breaking the skin, because Clostridium difficile will not grow and multiply in the shallow wounds, but you need to disinfect the wounds with saline and use iodine povine to disinfect the affected area thoroughly, so as not to aggravate the condition of the infection. 2. Deeper wounds: If the wound is long and deep, which is conducive to the growth and reproduction of tetanus bacillus, it is necessary to inject tetanus antitoxin in a timely manner, and at the same time, go to the hospital to carry out disinfection and bandage treatment, and the affected area should avoid touching water to prevent infection. It is recommended to go to the hospital for disinfection and X-ray and other routine examinations to avoid missing the condition and causing adverse effects.
