Clinical presentation and management of acute 2,4-D oral ingestion.
2,4-D, an extensively used herbicide, was intentionally ingested by a 61-year-old woman. An initial serum 2,4-D concentration of 392 mg/L was measured. The prominent clinical feature was marked central nervous system depression; primary laboratory abnormalities were extreme elevation of creatine kinase activity, and transitory elevation of AST and lactate dehydrogenase enzyme activities. Alkaline diuresis was initiated early and decreased the half-life of the drug from an initial 39.5 to 2.7h. It is concluded that alkaline diuresis to produce urine pH in the range of 7.5 to 8.5 should be considered in the management of an overdose patient with central nervous system depression and a history of 2,4-D ingestion.
