DiffIcult. History of injury, wound or after delivery is important. Pt has contractures of group of muscles like when smiling ironically ( sardonic smile), and contractures of limbs. Life-threatening neurologic syndrome characterized by tonic muscle spasms and hyperreflexiatetanus toxin can be detected in serum, confirming a clinical diagnosis. Samples should be collected before immunoglobulin treatment.
Not usually diagnose. Tetanus is very rare, given the almost universal administration of vaccine during childhood and after a penetrating wound if it's been more than 10 years since the last booster. The common name is lockjaw, which gives you an idea of what happens in this infection. The severe and continuous muscle spasms are produced by a toxin released by the clostridium tetani bacteria in susceptible wounds.
