The first thing you need to do is to get a good idea of what you are getting into. Not tetanus injection will not die mainly depends on whether the infection and the degree of infection, generally not infected or timely treatment will not die, but the infection is very heavy and not timely treatment, may lead to death. 1, not infected: if only a minor scrape or scratch, the wound does not ooze blood, ooze, or the wound is relatively superficial, does not have anaerobic conditions for the reproduction of Clostridium tetani, or clean wounds, such as blade cuts. Immediately rinse, disinfection and other proper treatment, these cases the human body generally will not be infected with Clostridium tetani, do not play tetanus injection usually does not cause harm, more will not die; 2, infection: if the wound is deep or relatively dirty, such as rusty nails, knives cause damage, may be infected with Clostridium tetani, and the formation of anaerobic or anaerobic environment, easy to cause the proliferation of Clostridium tetani. This situation if not actively tetanus injection, the human body is infected by Clostridium tetani, the condition changes more rapidly, if the treatment is not timely, may lead to the death of the patient, it is recommended to go to the hospital to deal with the wound and tetanus vaccine in a timely manner after the injury. There is usually an incubation period of about 10 days after tetanus infection, after which symptoms such as dizziness and weakness, weakness of chewing muscles, bitter smile face, closed teeth, corns, easily stimulated spasms, etc. may appear, and if tetanus infection is suspected, prompt medical attention is needed.
