Background: Caffeine is widely used as a stimulant drug throughout the world, and fatal arrhythmia is a known side-effect. We experienced a patient with caffeine intoxication causing fatal arrhythmias who was successfully treated with the infusion of propofol.
Case presentation: A 27-year-old woman was transferred to our hospital with nausea and poor general condition after intentional ingestion of 23.2 g of caffeine tablets. She was in cardiac arrest due to ventricular fibrillation just before hospital arrival. Advanced life support including defibrillation was started immediately, and we succeeded in resuscitating her 23 min later. Although she suffered from polymorphic ventricular premature beats and frequent transition to ventricular fibrillation, propofol administration converted her from a ventricular arrhythmia to sinus rhythm.
Conclusion: We report this case focusing on the cardiovascular effects of propofol and the lipid sink phenomenon. As a result, propofol could have the potential to suppress ventricular arrhythmias.
Keywords: Caffeine; intoxication; intralipid; propofol; ventricular fibrillation.
