Tetanus is mainly caused by tetanus bacillus invading the body through broken wounds to produce toxins. Strictly speaking, as long as there is bleeding from trauma, injection of tetanus antitoxin or tetanus immunoglobulin should be recommended. However, in everyday life, bumps and bruises can be avoided, and for superficial wounds or just abrasions, although there will be a small amount of bleeding, but after active disinfection and aseptic treatment, generally will not be infected with tetanus bacillus, there is no need to inject tetanus antitoxin. If the wound is deep or large, such as open fractures, burns, or wounds with contamination, as well as small but deep wounds or wounds that are small but large inside, the risk of infection with tetanus bacilli will be a little greater and tetanus antitoxin should be injected. In addition, newborns should also be injected with tetanus antitoxin promptly after the umbilical cord is treated to prevent the occurrence of neonatal tetanus. With the improvement of people’s health awareness, there may be some people who ask for tetanus antitoxin injection as long as there is a tiny skin break, and this practice is not unacceptable, so as to avoid tetanus bacillus infection to the maximum extent. Overall, the key to tetanus is prevention, as long as you pay attention to tetanus prevention, the use of effective preventive measures, you can greatly reduce the incidence of tetanus, it is recommended that patients appear wounds in a timely manner to seek medical advice, so that doctors give guidance program.
