Study information
Scientific title
Acronym
Study hypothesis
1. To investigate whether an increased stimulus dose is required to produce a tonic/clonic convulsion duration of greater than or equal to 15 s when propofol is used as an alternative to etomidate for anaesthesia during electroconvulsive therapy (ECT).
2. To investigate whether the incidence of cognitive side-effects is influenced independently by the anaesthetic agents propofol and etomidate, or as a consequence of differences in stimulus dose required for ECT. (Cognitive side effects to be measured by Folstein Mini-Mental State Examination [FMM], Paired Associate Learning Test [PALT], and subjective rating of memory).
