A bretylium tosylate overdose can cause prolonged central nervous system depression, mimicking brain death. Emergency physicians should recognize this effect and continue life support during bretylium toxicity.

Area of Science:

  • Cardiology
  • Neurology
  • Toxicology

Background:

  • Bretylium tosylate is an antiarrhythmic agent used in cardiac arrest management.
  • Myocardial infarction and cardiac arrest can lead to complex patient management scenarios.

Observation:

  • A 74-year-old patient received an 81.5-mg/kg intravenous overdose of bretylium tosylate following resuscitation from cardiac arrest.
  • The patient experienced prolonged neurological depression but ultimately recovered neurological function.

Findings:

  • This case highlights central nervous system depression as a potential adverse effect of bretylium tosylate overdose.
  • The severity of neurological depression may not correlate with the ultimate neurological outcome.

Implications:

  • Emergency physicians must be aware of bretylium tosylate's neurotoxic potential.
  • Premature termination of life support due to apparent brain death in bretylium overdose cases should be avoided.
  • Continued vigilance and supportive care are crucial in managing bretylium tosylate toxicity.
