An evaluation of combining thiopentone and etomidate for the induction of anaesthesia

Abstract

The characteristics of three combinations of thiopentone and etomidate lin the ratios of thiopentone (mg):etomnidate (mg) of 5:1, 13:1 and 25:11 have been compared with'the individual agents alone for the induction of anaesthesia. The incidence of pain on injection and abnormal movements was less with the combination containing the highest ratio of thiopentone to etomidate, when compared to etomidate alone. The mixtures did not otherwise confer any advantages over the individual agents.
