title: Subthalamic deep brain stimulation in Parkinson's disease under different anesthetic modalities: a comparative cohort study.
abstract: BACKGROUND
  The efficacy and feasibility of bilateral subthalamic deep brain stimulation (STN-DBS) for Parkinson's disease (PD) under general anesthesia (GA) has not been evaluated.
  
  
  OBJECTIVE
  We compared the outcome of patients under GA with those who were operated on under local anesthesia (LA).
  
  
  METHODS
  Thirty-three patients were assigned to the GA group (desflurane) and 19 patients were assigned to the LA group. Microelectrode recording (MER) was performed in both groups. The surgical outcomes of the patients were evaluated using the Unified Parkinson's Disease Rating Scale (UPDRS) after at least 12 months after surgery.
  
  
  RESULTS
  Postoperatively, there was no significant difference on the UPDRS scores in either groups. A significant deterioration in cognitive function in the GA group was observed (p = 0.017). The recorded electrode coordinates, the average tracts for the MER, and STN depth were comparable in both groups. The overall incidence of adverse effects did not show any difference except that the incidence of sialorrhea and dysarthria was significantly higher in the GA group.
  
  
  CONCLUSIONS
  Desflurane GA was shown to be a good alternative anesthetic method for PD patients undergoing DBS. Although the motor outcomes were comparable, a significant cognitive decline may be seen in the GA group with a higher occurrence of stimulation side effects.
