Thyrotoxic periodic paralysis and intravenous propranolol in the emergency setting.
A 27-year-old male of Malaysian descent presented to the Emergency Department (ED) with rapidly progressive flaccid paralysis that quickly compromised his respiratory effort. The patient was found to have a serum potassium of 1.9 meq/L, and was diagnosed as having an acute paralytic episode secondary to thyrotoxic periodic paralysis. The paralytic attack was aborted with a combination of potassium replacement and parenteral propranolol in large doses. We report the use of a rarely described, yet possibly more effective, therapy for an acute attack of thyrotoxic periodic paralysis.
