The patient is in a state of having a cold. During this time, if a part of the body is injured and the wound is deep, there is a possibility of infection by tetanus bacillus, which can cause corresponding clinical symptoms. This is because the deep wound facilitates the growth and reproduction of tetanus bacillus, producing exotoxins, mainly the spasm toxin, which can cause the patient to exhibit symptoms related to tetanus. Therefore, even if the patient has a cold, it is advised to seek timely medical treatment at a hospital for wound disinfection and to receive a tetanus antitoxin injection. Having a cold is not a contraindication for receiving a tetanus shot.

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 skin test take?

Tetanus is widely used clinically and is formally known as tetanus antitoxin. Therefore, if a patient is injured and the wound is deep, such as reaching the subcutaneous fat layer or even the muscle layer in severe cases, it is necessary to prevent tetanus infection by injecting tetanus antitoxin. Before injecting the tetanus antitoxin, it is mandatory to perform a skin test to prevent the patient from experiencing allergies, even severe clinical symptoms such as anaphylactic shock. During the skin test, generally, 0.1ml of tetanus antitoxin is diluted in 0.9ml of saline, and a skin test is performed on the forearm, observing for at least half an hour.

Where is the tetanus shot given?

Tetanus injections require administration into the muscle, typically in the deltoid or gluteus maximus, which is below the patient's shoulder or on the buttocks. Before administering a tetanus shot, a skin test is usually performed. The test takes place on the inner side of the forearm, where 0.1ml of the solution is injected. Patients might experience some pain during the tetanus shot, but most can tolerate it. The tetanus shot effectively prevents tetanus infections, especially in cases where the wound is deep with a small surface area that can create anaerobic conditions conducive to the colonization and proliferation of Clostridium tetani, leading to tetanus infection. Vaccination can effectively prevent some serious diseases.

Can tetanus be cured?

If the patient does not have severe complications, most cases of tetanus can be cured. Tetanus is usually a specific infection caused by toxins secreted by Clostridium tetani. The incubation period for tetanus is usually six to seven days, but it can be as short as within 24 hours or as long as several months or even years. Therefore, after cleaning a wound, it is important to get a tetanus vaccine at a formal hospital. When tetanus occurs, we should actively go to the hospital for formal and systematic treatment, as the vast majority of patients can be cured.

Can a festering wound lead to tetanus?

Wound suppuration and contracting tetanus are two different concepts. Wound suppuration primarily occurs when there is an infection at the wound site, which spreads due to lack of significant control over the infection focus. We need to actively locate the infection source, perform thorough surgical debridement and drainage, use sensitive antibiotics as needed globally, and change dressings in a timely manner to manage the infection. Tetanus, on the other hand, is typically considered when the wound is too deep and visibly contaminated, often by rusty, sharp objects causing the infection. In such cases, thorough surgical cleansing of the wound is essential to prevent surface contamination, along with the systemic use of tetanus antitoxin to reduce or prevent a tetanus infection.
