Amiodarone-Induced Life-Threatening Refractory Hypotension

Area of Science:

• Cardiology
• Emergency Medicine
• Pharmacology

Background:

• Amiodarone is a common emergency department treatment for arrhythmias.
• The incidence of amiodarone-related adverse events, especially life-threatening ones, is not well-documented.
• Existing literature offers limited information on severe adverse effects of amiodarone.

Observation:

• A male patient presented with chest discomfort and rapid atrial fibrillation.
• Initial beta-blocker treatment was ineffective for his paroxysmal atrial fibrillation.
• Amiodarone was administered as a second-line agent for rate control.

Findings:

• The patient developed severe, refractory hypotension following intravenous amiodarone administration.
• This hypotension necessitated inotropic support.
• Rapid-sequence intubation was required due to the severity of the adverse event.

Implications:

• Intravenous amiodarone carries a risk of causing severe and refractory hypotension.
• Clinicians should be vigilant for this potential adverse effect in emergency settings.
• This case underscores the importance of monitoring hemodynamic stability during amiodarone infusion.
