Clinical evaluation of pediatric ethylene glycol monobutyl ether poisonings.
Ethylene glycol butyl ether, CAS 111-76-2, an ingredient in many popular commercial window/glass cleaners, is known to produce equal if not greater toxicity than ethylene glycol when administered to animals. Treatment recommendations for human poisonings are based upon animal data and include the use of ethanol therapy to inhibit the production of toxic metabolites. No human experiential data exist to accurately assess human toxicity or to verify treatment modalities. A 5 month retrospective review of all glass cleaner ingestions reported to a regional poison information center disclosed 24 pediatric patients, ages 7 mo to 9 y, who ingested 5-300 mL of a liquid glass cleaning product containing ethylene glycol butyl ether. All ingestions were reported within 5 min of ingestion, and all 24 children were asymptomatic at that time and subsequently. The product concentrations of ethylene glycol butyl ether ranged from 0.5% to 9.9%. Two of the 24 children ingested > 15 mL and were treated by gastric emptying and 24 h hospital observation. Neither hospitalized child suffered symptoms consistent with hemolysis, nervous system depression, acidosis, or renal compromise. Dilution with oral fluids at home is considered appropriate treatment of pediatric ingestions of < 10 mL of a commercial liquid glass/window cleaners containing < 10% ethylene glycol butyl ether.
