The transmission pathways of tetanus bacteria are quite numerous. Moreover, tetanus is an acute disease. It invades the human body through skin and mucous membrane wounds, generally producing toxins and causing illness. Usually, if the wound is more obvious, or there is a higher chance of wound infection, the reproductive capacity of the bacteria may be stronger, and thus the risk of tetanus infection is higher. Typically, after the onset of tetanus, there are clear symptoms such as fever and chills. If muscle stiffness occurs, the symptoms might be quite severe, requiring immediate medical attention. Additionally, it's helpful to observe whether the patient has speech difficulties, eating troubles, and in severe cases, there may even be convulsions.

Which part of the body is the tetanus shot administered?

Tetanus shots are administered in the buttocks or the muscular part of the upper arm, typically given as a muscle injection. Tetanus shots must not be administered intravenously. Before administering a tetanus shot, a skin test is conducted. If the skin test is positive, it is necessary to switch to a tetanus immune globulin that does not require a skin test; if the skin test is negative, a muscle injection can be performed. Tetanus is caused by the colonization of Clostridium tetani in the human body, producing neurotoxins, leading to a specific type of infection. Therefore, if the wound is deep and heavily contaminated, it is essential to promptly treat with a tetanus shot.

Can I get a tetanus shot in the evening?

If a patient has a relatively deep wound, such as reaching the subcutaneous fat layer or even more severely, the muscle layer, it is important to prevent tetanus infection. It is advised that the patient must come to the hospital for a tetanus antitoxin injection into the muscle. After an injury, the sooner the tetanus antitoxin is injected, the better, as delays can affect the effectiveness of the antitoxin. Therefore, tetanus antitoxin can also be administered at night. Generally, one should go to the emergency surgery department of the hospital for the injection, as the emergency surgery department is on duty 24 hours a day, so it is possible to receive the tetanus shot at night.

Can you eat eggs if you have tetanus?

Tetanus patients should eat more light food, with low fat and sodium content, and avoid strong irritants, such as spicy foods. They can eat more foods containing protein, because sufficient protein in the body can help heal wounds and also provide enough energy for the patients, which is beneficial to their condition. Therefore, tetanus patients can eat a moderate amount of eggs.

Can I drink alcohol after getting a tetanus shot?

After receiving a tetanus shot, it is not allowed to drink alcohol. Alternatively put, if you drink alcohol, you should not get a tetanus shot. At the same time, one should avoid consuming spicy, stimulating foods, and foods that are likely to cause allergies, to prevent allergic reactions and local wound fever. Tetanus shots are primarily used for injuries, therefore, patients with injuries should not consume the aforementioned substances and are advised to eat foods high in protein and vitamins to promote wound healing. Moreover, it is also necessary to enhance local dressing changes. A tetanus shot is solely used to prevent infections caused by tetanus; only through thorough wound cleaning and improving the anaerobic environment can the presence of tetanus be potentially eliminated.

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.
