Tetanus is a medical condition characterized by an acute onset of hypertonia, painful muscle contractions (usually of the jaw and neck), and generalized muscle spasms without any other apparent medical causes. Symptoms are caused primarily by tetanospasmin, a neurotransmitter produced by the anaerobic bacterium ‘Clostridium tetani’.
A wound is classified as ‘tetanus-prone’ if it has one or more of the following characteristics.
1) Age of wound > 6hrs
2) Type of wound = Stellate (star shaped or radiating from central wound), abrasion, avulsion
3) Depth > 1cm
4) Mechanism of injury = Projectile, crush, burn, frostbite
5) Signs of infection present
6) Gross contamination (feces, saliva, grass, dirt) present
7) Ischemic tissue present
