Refractory status epilepticus, circulatory collapse after cardiac arrest, and acute respiratory distress syndrome caused by severe isolated fluvoxamine poisoning: a case report

Abstract

Case: A 30-year-old female ingested 21.75 g fluvoxamine in a suicide attempt. She presented with grand mal seizures and vomiting on admission to our Emergency Center, with a fluvoxamine serum concentration of 4.58 μg/mL. The patient was diagnosed with status epilepticus, which could not be fully suppressed with the maximum dosage of benzodiazepines. The patient also developed circulatory collapse after resuscitation for sudden cardiac arrest and acute respiratory distress syndrome, believed to be secondary to aspiration. Outcome: With venoarterial extracorporeal membrane oxygenation, a massive infusion of propofol successfully suppressed status epilepticus, and both the circulatory collapse and acute respiratory distress syndrome gradually improved; venoarterial extracorporeal membrane oxygenation and propofol treatments were then terminated, and the patient was discharged without further disabilities. Conclusion: Compared to all other reported clinical cases of fluvoxamine poisoning, the patient in this study ingested the highest dose and developed the most severe symptoms, but was successfully treated without any disabilities.
