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.

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.

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.

Can I take a bath after getting a tetanus shot?

It's not recommended to take a bath immediately after receiving a tetanus shot. First, the wound requiring a tetanus shot may either be deep, heavily contaminated, or relatively large. After receiving a tetanus shot in the buttocks or the deltoid muscle of the upper arm, it is essential to enhance wound dressing changes and keep the wound dry, which is why bathing is not advised. If it's just a simple tetanus injection site, it can generally be exposed to water a few hours later. However, other wounds on the body should be kept dry. Therefore, it is better to take a bath when wounds on other parts of the body have healed well to avoid worsening infections and delaying healing.

When does tetanus occur?

Tetanus is an infection caused by the invasion of the body by Clostridium tetani. Clostridium tetani is an anaerobic bacterium and an opportunistic pathogen, which is likely to cause tetanus in conditions such as anaerobic environments, deep wounds, or heavily contaminated wounds. Therefore, in cases where wounds are relatively small yet deep, and are considered to be in an anaerobic environment, or are contaminated with rust or soil, or in situations such as open fractures, blast injuries, gunshot wounds, and animal bites, tetanus injection treatment is necessary. It is generally recommended to administer the injection within 24 hours, and a skin test should be conducted before the injection, with alcohol consumption prohibited.

Does tetanus require a skin test?

After a patient is injured, if the wound is relatively deep, such as reaching the subcutaneous fat or deeper to the muscles, it is generally required to administer a tetanus shot. The most commonly used tetanus remedy in clinical practice is called tetanus antitoxin. Before administering tetanus antitoxin, a skin test must be conducted. This is because if an allergic reaction to tetanus antitoxin occurs, it can lead to anaphylactic shock, characterized by increased heart rate, decreased blood pressure, reduced blood oxygen saturation, with severe cases resulting in coma or even death. Therefore, it is clinically required to perform a skin test before administering a tetanus shot to prevent allergic reactions and the occurrence of anaphylactic shock.
