Autonomic dysfunction in severe tetanus

Abstract

We studied the use of continuous iv magnesium (Mg) infusion to control the sympathetic crises in a patient with severe tetanus characterized by pronounced autonomic nervous system instability. Our results suggested that Mg is a useful adjunct to the CNS depressants traditionally used. This therapy controlled the sympathetic crises and also suppressed the release of catecholamines, although Mg infusions alone appeared to be inadequate therapy.
