Tetanus is a disease in which the budding spores of Clostridium tetani, which develop into proliferators under hypoxic conditions, multiply rapidly and continuously produce exotoxins, mainly spasm toxins, causing a series of symptoms in patients. Tetanus is mainly seen in various traumas, especially in deep and narrow traumas, and also in newborns when the umbilical cord is broken under unclean conditions, which can cause maternal and neonatal tetanus. The typical symptoms of the patient are paroxysmal strong spasms on the basis of myotonic contractions, difficulty in opening the mouth (teeth closed), corkscrew, and in severe cases, asphyxia. The treatment is mainly to remove the toxin thoroughly, apply antitoxin to neutralize the free toxin, and keep the airway open. At the same time, avoid stimuli such as sound, light and water to induce seizures. Early and thorough debridement after trauma is the key method for tetanus prevention, which can also be combined with active or passive immunization.
