title: [Use of thiopental in man. Determination of this drug and its metabolites in plasma and urine by liquid phase chromatography and mass spectrometry].
abstract: Thiopental is an anaesthetic drug which is currently used for cerebral resuscitation. In this last indication the drug is administrated at high doses over a period of several days. Under clinical trials thiopental and two metabolites namely 5 ethyl-5 (1' methyl-3' hydroxy-butyl) 2 thiobarbituric acid and 5 ethyl-5 (1' methyl-3' carboxy-propyl) 2 thiobarbituric acid have been determined by high performance liquid chromatography and mass spectrometry. In human plasma high concentrations of thiopental and 5 ethyl-5 (1' methyl-3' hydroxy-butyl) 2 thiobarbituric acid and a lower concentration of 5 ethyl-5 (1' methyl-3' carboxy-propyl) 2 thiobarbituric acid have been found. In urine samples these metabolites are excreted in large and approximately equal quantities, whereas small amounts of thiopental were recovered.
