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.

tetanus early symptoms

Tetanus is an infection caused by Clostridium tetani, which enters the body through broken skin or mucous membranes and thrives in an anaerobic environment, producing toxins. Clinically, tetanus is characterized by lockjaw, episodic spasms, and rigid spasms, primarily affecting the muscles such as the masseter, latissimus dorsi, abdominal muscles, and limb muscles. Early symptoms of tetanus infection include general weakness, dizziness, headache, weak chewing, localized muscle tightness, pulling pain, and heightened reflexes.

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.

How many times can a tetanus shot be administered in a year?

The tetanus toxin vaccine is used for emergency vaccination. The main ingredient of this vaccine is the tetanus antitoxin. It is best to be vaccinated within 24 hours, and the sooner the vaccination is administered, the stronger the potential for protection. However, the duration of protection provided by the vaccine is not very long, and the effect of the tetanus antitoxin medication generally lasts about a week. Therefore, vaccination within 24 hours can effectively prevent problems that may occur within that week. Generally, there is no specific number for the annual frequency, but it is usually recommended not to exceed three times per year. Of course, this depends on the degree of injury. If there is a risk of infection, then the vaccine should be administered since its preventive effect is currently considered the best and can achieve significant efficacy.

How much is the tetanus serum?

When there is a potential risk of tetanus infection in our wounds, we should promptly receive a tetanus shot. The tetanus treatments commonly used today include tetanus antitoxin and tetanus immunoglobulin, also known as tetanus serum. Generally, the price of tetanus antitoxin is about seven to eight yuan each. Tetanus serum can be divided into two types: human tetanus immunoglobulin and horse tetanus immunoglobulin. The price of human tetanus immunoglobulin is slightly over 80 yuan, while horse tetanus immunoglobulin costs slightly over 30 yuan. Horse tetanus immunoglobulin requires a skin test before it can be administered.

Why is tetanus given three times?

Tetanus is often derived from horse serum, which is a heterologous protein that many people might be allergic to. This is why a sensitivity test is done before administering tetanus shots; a positive allergy test indicates the presence of this antigen in your body, which can lead to an allergic reaction. To prevent such allergic reactions, desensitization is performed through intramuscular injections, which means administering the tetanus vaccine in three separate doses. This approach helps avoid allergies or even severe anaphylactic shock that might occur from the tetanus shot.
