Summary

Under regional anesthesia, subthalamic nucleus deep brain stimulation (STN-DBS) has proven to be an effective therapeutic approach for improving motor symptoms in Parkinson's disease. However, a significant portion of Parkinson's disease (PD) patients is unable to cooperate with the surgery, necessitating the use of awake sedation. Nevertheless, the administration of anesthetic drugs often impacts the electrical signals recorded by microelectrodes to varying degrees. This study is designed as a prospective, randomized, placebo-controlled, double-blind, two-arm investigation. PD patients scheduled for bilateral STN-DBS surgery will be randomly assigned to either the Dexmedetomidine group or the Dexmedetomidine combined with Esketamine group. The differences in neural activity between the two groups will be assessed using the normalized root mean square (NRMS) method. The primary outcome measure is NRMS, while secondary outcome measures include differences in beta oscillation power spectrum analysis, postoperative delirium incidence, postoperative changes in sleep disturbances, postoperative depression, anxiety status, and occurrence of adverse events.

Conditions

  • PD - Parkinson's Disease
  • Deep Brain Stimulation
  • Esketamine

Interventions

DRUG

esketamine

After the craniotomy, a continuous infusion of ketamine at a rate of 0.3 mg/kg/h (0.3 ml/kg/h) is administered until the completion of electrode implantation, prior to microelectrode recording (MER) and electrode insertion. After the administration of the drug, close monitoring of the patient's blood pressure and heart rate is conducted to maintain circulatory stability.

DRUG

normal Saline

After the craniotomy, a continuous infusion of normal saline at a rate of 0.3 ml/kg/h is administered until the completion of electrode implantation, prior to microelectrode recording (MER) and electrode insertion. After the administration of the drug, close monitoring of the patient's blood pressure and heart rate is conducted to maintain circulatory stability.
