New trends in the management of tetanus.

The prevalence of tetanus reflects a failure of immunization. Prompt diagnosis and prediction of severity are crucial for the prevention of early life threatening complications and the institution of appropriate management. The current symptomatic treatment of heavy sedation, paralysis and artificial ventilation for 3-5 weeks for moderate and severe tetanus, is, even in the best centers, still associated with unacceptably high mortality, due to the disease and complications of the therapy itself. It is especially inappropriate for the developing world where intensive care resources are minimal. New options reported to avoid artificial ventilation and sedation are dantrolene (Dantrium, Procter and Gamble Pharmaceuticals), baclofen (Lioresal, Novartis) and magnesium. Magnesium therapy has the advantages of controlling spasms and sympathetic over activity without sedation. This simplifies nursing care and minimizes the need for ventilatory support except in the very severe disease and the elderly. Magnesium is recommended as the first-line therapy in tetanus.
