title: [Acute toxic exposure in children: an overview].
abstract: OBJECTIVE
  To review the literature on acute toxic exposure in children, excluding envenomations.
  
  
  METHODS
  MEDLINE review (emphasis on the past decade), including the American Academy of Clinical Toxicology and the European Association of Poison Centres and Clinical Toxicologists position statements and position papers (peer-reviewed information based on scientific evidence and broad consensus) on gastrointestinal decontamination, multiple-dose activated charcoal and urine alkalinization.
  
  
  RESULTS
  Acute toxic exposure in children is a common event, mainly in children under six years of age. Death is rare. Although widely employed, there is no evidence that gastrointestinal decontamination and multiple-dose activated charcoal improve the outcome of poisoned patients. Very few efficient antidotes are used on a consistent basis, and some of them are very expensive and not available in Brazil.
  
  
  CONCLUSIONS
  Ipecac syrup and cathartics should not be administered on a routine basis in acute toxic exposures in outpatient treatment. Excluding the contraindications, single-dose activated charcoal and gastric lavage may be considered within one hour of ingestion if a patient ingested a potentially toxic amount or a potentially lethal amount, respectively. Whole bowel irrigation, multiple-dose activated charcoal and urine alkalinization may be considered in a few situations. Fomepizole and octreotide are safe and efficient antidotes, which can be used in the treatment of alcohol (methanol and ethylene glycol) and sulfonylureas poisoning, respectively.
