Tetanus is a specific infection caused by the invasion of Clostridium tetani through skin or mucosal wounds, leading to muscle spasms. Tetanus mainly causes damage to the respiratory tract, digestive system, and cardiovascular system. If not treated promptly, it can lead to suffocation, respiratory failure, and endanger life. Tetanus is preventable; in cases of open wounds at risk of tetanus infection, tetanus antitoxin should be administered for emergency prevention. Tetanus is widely present in feces and soil and can invade the human body through dust or direct contamination of wounds, leading to infection. Wounds that are small, deep, or heavily contaminated all require preventive tetanus vaccinations.

Can you drink alcohol after a tetanus shot?

Before undergoing tetanus treatment, it is advised not to drink alcohol. This is because there are two types of tetanus injections: the tetanus toxoid, which requires a skin test, and the tetanus immunoglobulin, which does not require a skin test. Drinking alcohol causes the capillaries to dilate, leading to skin redness, which can affect the results of the skin test. A positive result in the skin test, indicated by skin redness, means that tetanus toxoid cannot be administered, and instead, the more expensive tetanus immunoglobulin must be used. Moreover, for deeper wounds such as open injuries and fractures, tetanus treatment is essential. Tetanus infection can have severe consequences if not treated properly.

Do I need a tetanus shot for a cut?

For patients with a cut on the epidermis, it is first important to determine what object caused the injury. If the injury is from a rusty iron object and the wound is small and deep, it is mostly considered that the patient needs local treatment. Firstly, the patient should wash the wound repeatedly under running water with soapy water, and then clean and disinfect locally with hydrogen peroxide. After air-drying, apply iodophor for disinfection, and finally cover with sterile dressing or a bandage. It is generally recommended that patients avoid getting the area wet for up to three weeks. Additionally, patients should consider getting a tetanus antitoxin or tetanus immunoglobulin injection within 24 hours. If the injury is from another type of object and the patient has already dressed the wound after local treatment, the likelihood of tetanus infection is generally considered lower. It is recommended that the patient change dressings in a timely manner and keep an eye on it. Moreover, within a month, the patient should avoid alcohol and eat less spicy and irritating foods.

Is the risk of tetanus high?

Tetanus occurs infrequently, but once it appears, the condition can be very severe and may lead to death if not treated promptly. Tetanus infection is mainly caused by infection with the tetanus bacillus. The tetanus bacillus is an anaerobic bacterium that exists everywhere in nature. If the wound is very deep with a small surface area, and the conditions inside the wound become anaerobic, if the tetanus bacilli inside the wound are not thoroughly cleaned, it could lead to the rapid reproduction of the tetanus bacilli, releasing tetanus toxin and causing a tetanus infection in the patient.

Does tetanus cause fever in its early stages?

Tetanus is actually a disease caused by the tetanus bacillus, generally entering the body after mucous membrane damage. In the early stages of tetanus, there usually are no fever symptoms. Fever typically appears in the middle to late stages. Generally, it is preceded by symptoms like episodic muscle spasms or tonic spasms. During this period, the incubation period can be about one week. In this time, the patient may experience symptoms such as general fatigue, headaches, and dizziness. Under circumstances where infection is likely, it is crucial to administer tetanus antitoxin promptly to effectively prevent the disease. Since the disease's morbidity and danger increase significantly in its middle to late stages, and the likelihood of death is also relatively high.

Is tetanus painful?

Tetanus is a specific infectious disease in surgery, caused by the exotoxin of Clostridium tetani. Tetanus infection can lead to rigid muscle spasms, which is a disease with a high mortality rate. Although its treatment is difficult, the prevention is effective, so tetanus infections can be avoided by vaccinating with the tetanus vaccine. The tetanus shot includes human tetanus immunoglobulin and tetanus antitoxin serum. The injection of human tetanus immunoglobulin is administered via muscle and is not very painful, generally tolerable. The injection of tetanus antitoxin serum, being a foreign protein to the body, requires an initial sensitivity test. The pain is evident, as the sensitivity test involves a skin prick.
