Tetanus symptoms can potentially begin with a fever during the early stage, generally occurring between six and ten days after injury, meaning symptoms can appear within 24 hours or several weeks post-injury. The shorter the incubation period, the more severe the symptoms and the higher the risk. Some patients may experience fatigue, headache, dizziness, restlessness, and possibly fever. Subsequently, typical symptoms of tetanus occur, primarily characterized by intense muscle contractions starting with the facial muscles. This includes difficulties in opening the mouth and lockjaw, among others. Thus, prevention is crucial for tetanus. When there is a local tissue injury, it is essential to promptly disinfect with hydrogen peroxide or iodine, followed by cleaning and suturing the wound and timely tetanus vaccination to prevent the disease.

How many tetanus shots are administered?

A tetanus shot is sufficient; tetanus treatment can be divided into tetanus toxoid, which requires a skin test, and tetanus immunoglobulin, which does not require a skin test. The tetanus bacillus is commonly found in anaerobic wounds and heavily contaminated wounds, such as those contaminated with soil and rust etc., which can lead to colonization of tetanus bacilli on human mucous membranes and invasion of the body, producing toxins that affect the jaw muscles and respiratory muscles, causing difficulty in breathing and, in severe cases, endangering life. Therefore, for patients who need antitetanus treatment, it is imperative to undergo such treatment, generally with just one injection.

How to treat tetanus?

Generally speaking, a tetanus shot needs to be administered intramuscularly, but a skin test must be conducted before injection because tetanus vaccines can easily cause allergic reactions. The skin test usually involves a subcutaneous injection on the palm side of the forearm, followed by an observation period of 15 to 20 minutes. If there is no redness or itching, and the skin test is negative, then the vaccine can be administered intramuscularly, usually in the buttock. However, if the skin test is positive, as indicated by symptoms like redness, significant itching, or even systemic symptoms such as dizziness and cold sweats, it shows that the skin test for tetanus is positive. In this case, one can opt for a desensitization injection of diluted tetanus vaccine, followed by intramuscular injections four times, once every half hour, needing about two hours to complete.

What are the circumstances in which a tetanus shot should not be administered?

Tetanus is a strict anaerobic bacterium. Clinically, for deeper contaminated wounds, especially those contaminated by soil or punctured by rusty iron objects, an active injection of tetanus vaccine is recommended. Generally, for superficial scratches or clean and shallow wounds, as long as proper wound cleaning is performed, it is usually not necessary to administer a tetanus shot. For patients who have completed a full course of immunization or booster immunization within the last ten years and have high antibody levels in the body, if the wound is small, superficial, and free of foreign bodies or necrotic tissue residue, it is not necessary to inject the tetanus vaccine. For wounds that are larger, deeper, and heavily contaminated, with substantial residues of foreign bodies and necrotic tissue, or in cases where thorough wound cleaning is not achievable, an enhanced injection of tetanus antitoxin or immunoglobulin should be administered.

How long does a tetanus shot last?

After receiving a tetanus shot, it generally lasts for about six months. However, if you are injured again after six months and the wound is heavily contaminated, such as with contaminated soil or rust, and the wound is large and deep, it is advised to undergo tetanus treatment again. The purpose of the tetanus shot is to prevent infection by Clostridium tetani, which is an anaerobic bacterium. It tends to proliferate in anaerobic environments and in conditions of heavy contamination by rust and soil. Therefore, if after tetanus treatment the injury is relatively minor, shallow, and comparatively clean, it is sufficient to clean and dress the wound and keep it dry. If the wound is heavily contaminated, large, and deep, it is recommended to administer the tetanus shot again.

What are the symptoms of tetanus sequelae?

Tetanus, a viral infection problem, is actually quite a common disease. Usually, if the wound is deep or caused by rusty metals, there is a higher possibility of it leading to a tetanus infection. This condition requires timely treatment or prevention, otherwise, it can easily lead to complications. For example, tetanus typically causes complications primarily related to the lungs, such as pneumonia and pulmonary edema, among other issues, which are quite typical. The infected individual may experience symptoms such as difficulty breathing, coughing, nausea, etc., all of which could be a result of tetanus bacteria infection. In the case of a deep wound, it is crucial to promptly administer a vaccine to prevent exacerbation of the infection, and local treatment should be performed to effectively prevent it.
