Tetanus
Do you get a fever during the early stages of tetanus?
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 long does the tetanus shot last?
The duration of the effectiveness of a tetanus shot depends on whether tetanus antitoxin or tetanus immunoglobulin is administered following a suspected tetanus infection. Both types are forms of artificial passive immunity, providing immediate specific immunity after injection, mainly for treatment or emergency prevention. The metabolism and immune duration of these two injections vary: generally, tetanus antitoxin lasts about seven days, while tetanus immunoglobulin can last up to three weeks. Therefore, the specific duration of the effectiveness of a tetanus shot must be determined based on the individual injection circumstances. For suspected tetanus infections, it is generally advised to administer the injection as soon as possible. It's not that the injection will be ineffective if administered after a certain time, but rather that effective prevention before the onset of the disease can still be beneficial.
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.
Where to get a tetanus shot?
Tetanus can be treated in any department, but generally, after an injury, one would first go to the emergency room. Therefore, tetanus is very common in emergency medicine. Tetanus is a type of anaerobic bacterium that is ubiquitous in nature. If a person has a wound that is small and deep, the internal environment can become anaerobic, which easily leads to rapid proliferation of tetanus. At this point, it is necessary to inject tetanus immunoglobulin into such wounds. It is best done within 24 hours because after a long period, the tetanus bacillus might have already proliferated in the wound. A skin test should be performed before the injection, and the injection can only proceed if the skin test is negative. If the wound is relatively large and severe, it generally will not be infected by tetanus bacillus.
Can a tetanus shot be administered again?
If a tetanus shot is administered within 24 to 48 hours after injury, it can effectively prevent tetanus. However, if the tetanus shot is given a week or more after the injury, the effectiveness and relevance of the booster are generally not ideal. In such cases, tetanus immunoglobulin can be used for comprehensive antibody therapy to treat and prevent tetanus. Therefore, when the body sustains external injuries or certain infectious foci, it is crucial to promptly administer a tetanus shot intramuscularly, ideally within 24 hours, to effectively stimulate the body to produce the corresponding antibodies for protection.
Can you get tetanus if there's no rust?
For patients, if a wound occurs without rusting, there is still a possibility of tetanus. This is because if the wound is deep, it can lead to an infection by anaerobic bacteria. Therefore, it is recommended to go to the surgical department for thorough debridement and disinfection as soon as possible. At the same time, pay attention to resting, keeping the wound clean and dry, changing dressings on time, and taking oral antibiotics if necessary, such as cephalosporins, to prevent infection. Generally, with good control, recovery will be quick. However, tetanus can still occur, so it is still necessary to pay attention. Afterwards, keep the wound clean and dry, be mindful of your diet, avoid spicy and irritating foods, and follow up with your doctor.
How long should you avoid certain foods after getting a tetanus shot?
Tetanus antitoxin medication serves a preventative function and is commonly used as a vaccine. Receiving a tetanus shot is essentially aimed at preventing infections from the tetanus bacterium. Generally, there are dietary restrictions to follow after getting the shot. The effect of this medication typically lasts about a week, during which it is necessary to observe these dietary restrictions. It is usually advisable to avoid spicy or cold foods, such as chili peppers, beef, lamb, dog meat, or seafood. These should be eaten sparingly or avoided altogether. Otherwise, these spicy foods might directly affect the efficacy of the tetanus antitoxin. In such cases, the prevention of tetanus infections could be significantly reduced, thereby increasing the likelihood of contracting tetanus bacterium.
Is it necessary to get a tetanus shot?
Getting a tetanus shot is very necessary if a patient has had an injury or has wounds on the body. Without a tetanus shot, there might be a risk of tetanus infection. The main reason is due to the presence of tetanus bacillus spores in the natural environment, which could colonize within the wound if it's exposed. This can potentially lead to a tetanus infection. Severe cases can present with symptoms such as opisthotonos, breathing difficulties, suffocation, and could even lead to death. The tetanus shot involves injecting tetanus antitoxin into the patient's body, which is a form of passive immunity and can prevent some symptoms of tetanus infection.
How to administer a tetanus shot if it is negative?
A negative tetanus needle test indicates that the patient is not allergic to the tetanus antitoxin and can continue with intramuscular injections, typically administered in the upper arm or buttock muscles, in doses ranging from 1000 to 3000 units each time. If the infection is severe or the tetanus injection is not timely, the dosage may be appropriately increased, generally by one to two times. The purpose of administering tetanus antitoxin treatment is to prevent infection by Clostridium tetani, an anaerobic bacterium. For patients with deep wounds or heavily contaminated wounds, such as those contaminated with soil or rust, Clostridium tetani can easily colonize. Therefore, for such patients, it is essential to perform tetanus antitoxin treatment while cleaning and dressing the wound.
Will a scrape lead to tetanus?
When a tetanus infection occurs, the wound is generally quite deep, for instance, reaching the subcutaneous fat or even the muscle layer in severe cases. Such deep wounds can create an anaerobic environment, which is conducive for the growth and reproduction of Clostridium tetani, an anaerobic bacterium. This bacterium produces exotoxins, primarily the tetanospasmin, which causes the associated clinical symptoms in patients. If it's merely a scrape or a superficial wound, tetanus infection is unlikely. Clinically, what is needed for such abrasions is to disinfect the area with iodine and then bandage it appropriately.
