A case approach: the pathophysiology of thyroid storm.

As is illustrated in the case report presented here, disorders other than malignant hyperthermia can lead to fever and tachydysrhythmias. Should such symptoms develop in a patient with a previous history of thyrotoxicosis, the possibility of thyroid storm should be considered. Careful monitoring must not cease with the termination of the operation, because this complication usually develops after surgery. Should the complication occur, a successful outcome is dependent upon an understanding of the pathophysiology of the disease process, aggressive monitoring, and appropriate pharmacological management.
