A one-year-old white female ingested approximately two to three grams of caffeine (200-300 mg/kg). The patient survived the ingestion with a maximum caffeine concentration of 385 micrograms/ml four hours postingestion. The child developed ventricular arrhythmias, seizures, metabolic disturbances, and severe pulmonary edema. She survived without apparent long-term sequelae despite having reached a serum caffeine concentration that is the second highest reported level in a survivor.
