Abstract: | We have developed a rapid, simple and precise gas chromatographic headspace analysis for sevoflurane in blood which circumvents problems associated with the high volatility and low blood/gas partition coefficient of this anesthetic drug. Blood standards are easily prepared by volumetric addition of a saturated aqueous solution of sevoflurane. Likewise, internal standardization is achieved using a saturated aqueous solution of halothane. Chromatographic conditions are similar to those commonly used for the analysis of blood ethanol. A simple method is also described for the preparation of stable and precise, aliquots of quality control materials for this assay. |
