Whether tetanus vaccination is necessary for an abrasion depends on the severity of the injury. For a minor abrasion where the wound is not deep, you can repeatedly rinse the wound with hydrogen peroxide or saline solution to wash off contaminants. After that, disinfect with iodine and perform simple bandaging. Change the dressing as needed. Such abrasions do not require a tetanus shot. However, if the abrasion is severe, the wound is deep, heavily contaminated, or caused by rusty metal, it is essential to receive tetanus vaccination while cleaning the wound in the hospital to prevent tetanus.

Do you get a fever during the early stages of tetanus?

Tetanus symptoms can potentially begin with a fever during the early stage, generally occurring between six and ten days after injury, meaning symptoms can appear within 24 hours or several weeks post-injury. The shorter the incubation period, the more severe the symptoms and the higher the risk. Some patients may experience fatigue, headache, dizziness, restlessness, and possibly fever. Subsequently, typical symptoms of tetanus occur, primarily characterized by intense muscle contractions starting with the facial muscles. This includes difficulties in opening the mouth and lockjaw, among others. Thus, prevention is crucial for tetanus. When there is a local tissue injury, it is essential to promptly disinfect with hydrogen peroxide or iodine, followed by cleaning and suturing the wound and timely tetanus vaccination to prevent the disease.

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.

What should I do if the tetanus test is positive?

A positive tetanus result generally refers to a positive result in the tetanus antitoxin skin test. Tetanus antitoxin is primarily used to prevent tetanus infections. Some patients may experience allergic reactions to tetanus, manifesting as localized swelling, mild fever, and general discomfort during the skin test. In such cases, a desensitization injection method can be chosen, which involves administering the tetanus shot in several doses at intervals. Alternatively, tetanus immunoglobulin can be used, which is more expensive on the market but has the advantage of not requiring a skin test. It can be administered directly, safely, and effectively.

Can getting ear piercings lead to tetanus?

Piercing ears generally does not result in a tetanus infection. Since the wounds from ear piercings are relatively small, they basically reach aerobic conditions. Tetanus bacillus are anaerobic bacteria and generally do not proliferate in an aerobic environment. In an anaerobic environment, however, tetanus bacillus can proliferate extensively, which is when a patient might show symptoms of tetanus. However, the specific condition of the patient's ears must also be considered. If the patient’s earlobes are very thick, the small external opening from the piercing might create an anaerobic environment within the middle of the earlobe. If tetanus bacillus colonizes inside the wound, it may lead to extensive proliferation of the bacteria.

How many years does the tetanus vaccine last?

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.
