ESTIMATION OF BLOOD ENFLURANE CONCENTRATIONS BY GAS-LIQUID CHROMATOGRAPHY
Royal Belfast Hospital for Sick Children Belfast, Northern Ireland
Department of Anaesthetics, The Queen's University of Belfast Northern Ireland
A simple and reliable method for the estimation of enflurane concentrations in whole blood is described. This involves extraction with n-heptane and estimation by gasliquid chromatography using methoxyflurane as an internal standard. Reproducibility was good and extraction from whole blood was reliable.
