تعريف

Tetanus is a bacterial infection. The infection affects the nervous system. It can lead to severe muscle spasms. Such spasms lead to lockjaw. This spasm makes it impossible to open or close the mouth. Tetanus can be fatal.

أسباب

Tetanus bacteria is found in soil, dust, or manure. It enters your body through a break in the skin.

Once in your body, the bacteria creates a toxin. This toxin causes tetanus.

عوامل الخطر

Factors that increase your risk of tetanus include:

  • Lack of tetanus vaccination (or not updating tetanus vaccination in timely manner)
  • IV drug use
  • العمر: 50 أو أكبر
  • Skin sores or wounds
  • الحروق
  • Exposure of open wounds to soil or animal feces

الأعراض

Symptoms of tetanus may include:

  • الصداع
  • Stiff jaw muscles (lockjaw) or neck muscles
  • Drooling or trouble swallowing
  • Muscle spasticity or rigidity
  • التعرق
  • حمى
  • التهيج
  • Pain or tingling at the wound site
  • النوبات
  • صعوبة في التنفس
  • Heart beat that is irregular, too fast or too slow

التشخيص

The doctor will ask about your symptoms and medical history. A physical exam will be done. The diagnosis is mainly based on the medical history.

Your doctor may test the wound. A culture will grow the bacteria causing the infection. Culture results are not always accurate for tetanus.

العلاج

قد يشمل العلاج ما يلي:

  • Hospitalization—to manage complications of the infection
  • Opening and cleaning of the wound—entire wounded area may need to be surgically removed
  • مضادات حيوية
  • Tetanus immune globulin—antibodies against tetanus that help neutralize the tetanus toxin
  • A tetanus shot—if your tetanus vaccine is not up to date
  • Medication to treat symptoms—may include antiseizure medication or muscle relaxants

Tetanus can cause severe problems with breathing or swallowing. A breathing tube may be inserted in the throat. This will help keep the airway open until you heal. A surgical procedure called a tracheotomy may be done. This will provide an open airway if your upper airway can not be accessed.

الوقاية

The best means of prevention is immunization. Immunization schedule for tetanus is as follows:

  • All children (with few exceptions) should receive the DTaP vaccine series. This protects against diphtheria, tetanus, and pertussis.
  • الأطفال الذين تتراوح أعمارهم بين 11-12 years that have completed the DTaP series of shots will receive another vaccine called Tdap.
  • Adults should receive a booster dose of the tetanus and diphtheria vaccine (Td) every 10 years. They may also receive this vaccine after an exposure to tetanus. It is not harmful to receive a tetanus vaccination earlier than 10 years.

If you or your child has not been fully vaccinated, talk to the doctor. There are catch-up schedules available.

In addition to the vaccine, you can prevent tetanus by taking proper care of wounds:

  • Promptly clean all wounds.
  • See your doctor for medical care of wounds.
