Tetanus vaccines generally involve an active immunization process against tetanus with a complete immunization schedule, providing effective protection for up to ten years for those who have completed the full course of prevention.

Typically, newborns must receive three doses of the DTP (diphtheria, tetanus, pertussis) vaccine, with the first dose administered at three months of age, followed by a dose each subsequent month, and booster shots at eighteen months or six years of age. If vaccinated, no further tetanus antitoxin or tetanus immunoglobulin injections are required for injuries incurred within ten years of vaccination.

If no active immunization has been done and the wound is heavily contaminated, it is crucial to promptly administer tetanus antitoxin or tetanus immunoglobulin. A skin test must be performed before using tetanus antitoxin; if the test is strongly positive, immunoglobulin should be administered for preventive treatment.

Can you get tetanus from a plastic scratch?

In clinical practice, all injuries, if the wound is relatively deep, such as being cut by a sharp object into the subcutaneous tissue or even damaging the tendons, reaching the muscle tissue, can potentially be infected by tetanus. Wounds inflicted by plastic can also be infected by tetanus. In such deep wounds, Clostridium tetani can easily grow and reproduce. This bacterium can produce a toxin that causes muscle spasms, leading to related clinical symptoms. Therefore, if a plastic injury results in a deep wound, there is a risk of tetanus infection. It is advised that the patient seeks medical attention promptly, undergoes wound disinfection, and receives an injection of tetanus antitoxin to prevent infection.

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.

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.

What are the complications of tetanus?

The main complications of tetanus primarily include suffocation, atelectasis, and pulmonary infections. Patients with severe conditions should have a tracheotomy performed as soon as possible to improve ventilation and clear the respiratory tract secretions. At the same time, artificial assisted breathing can be conducted, and hyperbaric oxygen therapy can be used as an adjunctive treatment. Care during tracheotomy should focus on airway management, including airway nebulization, humidification, flushing, and prevention of pressure sores, utilizing strict aseptic techniques to prevent cross-infection and subsequent pulmonary infections. Antibiotics should be selected based on the type of bacteria, and dedicated personnel should be assigned for nursing to prevent injuries from biting the tongue.
