Acute arsenic toxicity is rare, and there have been no pediatric cases of acute arsenic poisoning in the recent literature. We report a pediatric case of acute arsenic ingestion treated initially with British antilewisite (BAL) and D-penicillamine (DP), and later with dimercaptosuccinic acid (DMSA). A 22-month-old girl ingested 1 oz 2.27% sodium arsenate and developed immediate vomiting and diarrhea. ⋯ White blood cell count and renal and hepatic function remained normal. The excretion half-life was approximately 2.5 days, which is at least 2 to 3 times faster than the spontaneous excretion half-life expected in adults. Long-term follow-up was unavailable.(ABSTRACT TRUNCATED AT 250 WORDS)
