- Primary Outcome Measures
Name Time Method Main Objective: Study whether there are changes (and their characteristics) in local field potentials recordings in deep subcortical structures, obtained through the stimulators implanted to treat Parkinson's disease, with the administration of dexmedetomidine and propofol.;Secondary Objective: Make a comparative analysis of possible changes in the patient´ score of the UPDRS-III scale at ?off? situation, with dexmedetomidine and different estimated plasma levels of propofol.;Primary end point(s): Registration signal potency of deep brain activity at different frequencies through the stimulator (microvolts?m-2).;Timepoint(s) of evaluation of this end point: In baseline situation without anesthetic medication (day 4), with dexmedetomidine (day 1) and after different concentrations of propofol (day 6).
