Review Case Reports
[Clinical features of tetanus: a review with case reports].
Tetanus is a CNS disorder characterized by muscle spasms that is caused by the exotoxin of an anaerobic bacterium, Clostridium tetani. This disease is killing tens of thousands of neonates in developing countries. Although the incidence and mortality of tetanus has dramatically dropped in developed countries due to effective vaccination, appropriate wound management, and recent advances in intensive care, treatments remain difficult. ⋯ No patients died due to ICU managements, in which the most useful were propofol for spasm control and sedation, and magnesium sulfate for autonomic overactivity. Retrospectively, the Tetanus Severity Score (TSS) for mortality proposed by Thwaites et al (2006) is considered a useful tool also for predicting the clinical outcome at discharge. Although tetanus has been traditionally classified into the generalized, local, and cephalic types, a simpler severity-based classification into "severe", "moderate", and "mild" types may be more practical with regard to disease management.
