Suspected seizure-survival of a lethal dose of the rodenticide alpha-chloralose.

A 58-year-old female was admitted due to a suspected seizure. A blue colored pharyngeal fluid was visualized during intubation, which is indicative of poisoning. Clinical research revealed an ingestion of 2.4 g of alpha-chloralose, a rodenticide with a lethal dose of 1 g. Immediate detoxification by gastroscopy, gastric lavage and hemodialysis led to full recovery. Substance detection was carried out by gas chromatography-mass spectometry of a urine sample. There are only a few cases reporting poisoning by this substance. Coma and bilateral myoclonus have been reported but blue gastric fluid as the "red flag" in this case has never been described.
