Treatment of methylene chloride induced carbon monoxide poisoning with hyperbaric oxygenation.

Methylene chloride is an organic solvent with many industrial uses. Inhalation of methylene chloride fumes can result in toxicity, caused by hepatic biotransformation of methylene chloride to carbon monoxide. A case of acute methylene chloride poisoning is presented, including successful treatment of this patient with the use of hyperbaric oxygenation. The rationale for the use of hyperbaric oxygenation in the treatment of methylene chloride poisoning is discussed.
