PROPOFOL - CONTRASTING EFFECTS IN MOVEMENT-DISORDERS

We report two patients presenting for thalamotomy in whom tremor was a bolished for 8 h after propofol anaesthesia. Propofol has two contrast ing actions. It may have an anti-Parkinsonion effect, abolishing abnor mal limb movements. On other occasions, propofol is known to induce sp ontaneous abnormal limb movements, as well as epileptiform activity. P ropofol is probably best avoided for stereotactic procedures. It is di fficult to reconcile these two opposing actions.
