Tetanus is a specific infection often associated with trauma. In addition to various traumas, it can also occur in parturient women and newborns under unsanitary conditions. The pathogen is Clostridium tetani, an obligate anaerobe that stains positive under Gram staining conditions. Normally present in the intestines of humans and animals, it is distributed in nature and common in soil. This type of bacteria has strong resistance to environmental conditions and can withstand boiling.

Can tetanus be fatal?

Tetanus can be fatal if not treated promptly. When infected with tetanus, early symptoms primarily include dizziness, headache, fatigue, decreased appetite, weak chewing, and sore jaw muscles, some may also exhibit increased reflexes or muscle rigidity. As the condition worsens, some patients show typical tetanus symptoms such as lockjaw, difficulty opening the mouth, risus sardonicus, opisthotonos, and stiff neck. As the condition further deteriorates, it can lead to difficulty breathing, or even respiratory arrest, and cardiac arrest. If not promptly rescued, the patient can die.

How is tetanus diagnosed?

The diagnosis of tetanus requires comprehensive consideration. If the patient has a history of trauma with skin or mucosal wounds, and shows signs of muscle spasms, such as difficulty opening the mouth, stiffening of the neck, and increased reflexes, the possibility of a tetanus infection should be considered. Further, a culture of the wound can be conducted to see if Clostridium tetani can be cultured. If the culture is positive, a definitive diagnosis can be made. Additionally, tetanus needs to be differentiated from other diseases such as purulent meningitis, rabies, epilepsy, hysteria, and so on.

Which department do I go to for a tetanus shot?

Tetanus shots are widely used clinically, and patients generally receive the injection after sustaining an injury. Therefore, it is recommended that patients visit the surgical department. If at a community hospital, they should go to the surgical outpatient clinic. If in a secondary or tertiary hospital, patients can go to the surgical outpatient clinic or the emergency surgery department for treatment. After wound treatment, they can receive a tetanus shot as required. Thus, patients usually go to the surgical department or emergency surgery for the tetanus injection.

Do not get a tetanus shot before a certain age.

Tetanus antitoxin, this type of vaccine, generally has no significant age restrictions. It is usually best not to administer it before the age of one, as it involves using a toxin to combat toxins and prevent certain diseases. Therefore, it is advised not to vaccinate before one year of age. However, not everyone needs to be vaccinated against tetanus; it only serves as a preventive measure and is only necessary if there is a possibility of infection. For instance, vaccination is required when there are deep wounds or apparent injuries from rusty metal, as these conditions have a higher risk of infection. In such cases, administering tetanus antitoxin can effectively prevent infection. Thus, vaccination should depend on the specific situation rather than on age.

What should I do if I am allergic to tetanus shots?

The full name of the tetanus shot is tetanus antitoxin serum, which is mainly made from horse serum and has certain allergenic properties. If a patient is allergic to tetanus antitoxin serum, desensitization injections can be used, which involves gradually injecting one milliliter of the tetanus antitoxin serum into the body in four or more sessions, with each injection spaced about twenty to thirty minutes apart. After each injection, it is important to closely observe the patient's reaction, including checking for signs of itching in the nose, hives throughout the body, or difficulty breathing. If any of these symptoms occur, emergency treatment should be administered. If the injections of tetanus antitoxin serum cannot be completed multiple times, or if the patient is unwilling to accept this method of injection, tetanus immunoglobulin can be administered instead of tetanus antitoxin serum. Tetanus immunoglobulin does not require a sensitivity test and can be directly injected into the body without causing an allergic reaction, although it is more expensive.
