title: Formate levels following a formalin ingestion.
abstract: Although formalin ingestions have previously been reported in the literature, technology has only recently been developed to measure both formaldehyde and formate levels in plasma. Methanol, formaldehyde, and formate levels were followed in the case reported here until the patient's death approximately 13 h after the ingestion. The clinical course was marked by an initial profound CNS depression followed by an apparent clinically quiescent period. Severe abdominal pain and retching preceded the development of seizures, DIC, severe hypotension, and cardiac arrest. Methanol levels rose throughout this 13-h course. Formate and formaldehyde levels increased until bicarbonate and ethanol therapy were instituted. The "fixing" of the stomach by formaldehyde may have produced delayed absorption following formalin ingestion. Therapeutic implications are discussed.
