Objective:To evaluate the effect of general anesthesia on microelectrode recording (MER) during deep brain stimulation (DBS) of subthalamic nucleus (STN) in the patients with primary Parkinson′s disease (PD).Methods:Forty-four patients of both sexes with primary PD (duration of disease ≥ 5 yr and/or obvious symptom fluctuation), undergoing bilateral STN DBS from March 2008 to March 2018, aged<80 yr, were selected and divided into 2 groups by a random number table method: awake group ( n=26) and general anesthesia group ( n=18). In awake group, 0.5% ropivacaine was used for incision infiltration at skin incision.Patients in GA group received propofol and remifentanil by target-controlled infusion with Narcotrend to monitor the depth of anesthesia, and 0.5% ropivacaine was used for incision infiltration at skin incision.The total number of trajectories and length of STN were recorded during MER.Movement disorders were evaluated at 1 week before surgery and 6 months after surgery, and the improvement rate of dyskinesia was calculated.The postoperative anesthesia-, hardware- and stimulation-related complications were recorded. Results:There were no significant differences between the two groups in the total number of trajectories, length of STN and improvement rate of postoperative movement disorders ( P>0.05). Conclusion:General anesthesia does not affect the MER during STN DBS in the patients with primary PD.
