Tetanus is a very serious infectious disease, if there is trauma, especially if the wound is relatively large or deep or the wound is contaminated, you should be injected with tetanus antitoxin to prevent the occurrence of tetanus. It also depends on how the situation is. If the needle prick wound is not very deep, only need to do a good job of wound disinfection treatment can, no need to inject tetanus antitoxin. If the wound is deep, in addition to strict cleaning of the wound, aseptic treatment, should also be timely injection of tetanus antitoxin, because the deep wound will be relatively in the wound in a low-oxygen environment, very suitable for the growth and reproduction of tetanus bacteria and tetanus induced. If the needle is rusty, or after being contaminated by dirt, etc., it is even more important to inject tetanus antitoxin, because it is more likely to cause tetanus bacillus and other bacterial infections. Since tetanus antitoxin can cause allergic reactions, a skin test should be done before injecting tetanus antitoxin. If the skin test is negative, the injection can be given directly; if the skin test is positive, the injection can be completed by desensitization injection, or it can be replaced with tetanus immunoglobulin. Whether or not to inject a tetanus shot after being stuck by a needle needs to be treated separately according to the specific situation. In short, it is recommended that patients seek medical attention early and let the doctor decide on the specific situation without delay to avoid aggravation.
