Tetanus: aka lockjaw, is an infectious, acute disease that is life-threatening, which is characterized by painful, uncontrollable contraction of skeletal muscle.
Etiology: Caused by a toxin, produced by the bacillus bacterium which is Clostridium tetani. It is in animal feces which gets mixed into soil. If it enters through an anaerobic wound, it grows, produces a dangerous toxin and travels in the bloodstream.
Anaerobic: living without oxygen.
Symptoms: jaw muscles are affected first with tetany that prevents the mouth from opening. Other symptoms like a high fever, tachycardia, intense pain and dysphagia can also occur.
Tetany: hyperirritability of the muscles causing a spasm-like condition; usually the result of a lack of calcium
Diagnosis: An involuntary contraction of the muscles in the back of the throat that causes the patient to bite down, is a positive result of a spatula test.
Treatment: Cleansing of wounds will help. Receiving an antitoxin to bind and inactivate the tetanus toxin should treat it.
