Understanding Tetanus
Tetanus is a serious disease of the nervous system caused by a toxin-producing bacterium. The disease causes muscle contractions, particularly of your jaw and neck muscles.
Key Fact: Tetanus is commonly known as lockjaw because the condition often causes your jaw muscles to lock, making it hard to open your mouth or swallow.
Common Symptoms
Jaw Cramping
Difficulty opening the mouth and a stiff, locked jaw (lockjaw).
Muscle Spasms
Painful, involuntary muscle contractions, often triggered by noise, physical touch, or light.
Stiff Neck and Abdomen
Tightness and rigidity in the muscles of the neck and stomach area.
Difficulty Swallowing
Trouble swallowing (dysphagia) due to throat muscle spasms.
Risk Factors
- Not being vaccinated or having an expired booster
- Deep puncture wounds (nails, splinters, bites)
- Chronic sores or infections
- Dirty injuries (soil, manure)
Diagnosis & Treatment
Diagnosis
There are no laboratory tests for tetanus; diagnosis is based on clinical signs and symptoms.
Common Treatments
-
Tetanus Antitoxin: Medications like tetanus immune globulin to neutralize the toxin that hasn't yet bonded to nerve tissue.
-
Sedatives: Drugs to control muscle spasms and reduce restlessness.
-
Ventilator Support: Intensive care for patients whose respiratory muscles are affected by spasms.
