STUDIES OF DRUGS GIVEN BEFORE ANAESTHESIA II: A METHOD FOR THE ASSESSMENT OF THEIR INFLUENCE ON THE COURSE OF ANAESTHESIA

SUMMARY The problems encountered in the evolution of a method for assessing the effect of pre-operative drugs on the course of anaesthesia are discussed. A method based on the use of methohexitone or thiopentone with nitrous oxide and oxygen for the operation of dilatation and curettage is described. The observations which it is feasible for the anaesthetist to record during the technique are described and methods for the analysis of data are discussed.
