Unintentional Pediatric Ingestion of Electronic Cigarette Nicotine Refill Liquid Necessitating Intubation.

Liquid nicotine used in electronic cigarette devices is highly concentrated, unreliably packaged, and poorly regulated. We present a case report of a 6-year-old female who developed severe toxicity and required intubation after an unintentional oral ingestion of approximately 703 mg (35 mg/kg) of liquid nicotine, with accompanying serum and urine concentrations of nicotine and its metabolites. Analysis of the ingested liquid suggests a nicotine concentration of 140.6 mg/mL in the purchased commercial product, or 234% of its labeled concentration. Clinicians should be aware of these products and the potential severity of toxicity they may incur.
