Abstract
We report two patients presenting for thalamotomy in whom tremor was abolished for 8 h after propofol anaesthesia. Propofol has two contrasting actions. It may have an anti-Parkinsonion effect, abolishing abnormal limb movements. On other occasions, propofol is known to induce spontaneous abnormal limb movements, as well as epileptiform activity. Propofol is probably best avoided for stereotactic procedures. It is difficult to reconcile these two opposing actions.
