Summary

Dexmedetomidine (DEX) sedation is widely used in deep brain stimulation implantation (DBSI) of patients With Parkinson's disease. However, intraoperative application of DEX may affect the discharge activity of deep brain nuclei and reduce the discharge frequency of Subthalamic nucleus (STN) neurons. At present, there is still a lack of prospective intervention research to explore the optimal dose that does not affect MER mapping in patients with Parkinson's disease. The present study uses the Dixon and Massey up-and-down method to analyze the EC50 of DEX in patients with PD undergoing STN-DBS sedation, to clarify the balance meets the sufficient comfort of patients without affecting the accurate target of MER and the optimal dosage of DEX for boundary recognition.

Conditions

  • PD - Parkinson's Disease

Interventions

DRUG

Dexmedetomidine

The loading dose of DEX (0.5 µg/kg) is transfused intravenously within 15min.The maintaining concentration of DEX, which is started at 0.3 µg/kg/h in the first patient, is determined by the NRMS in the MER signal of the previous patient according to the up and down sequence. If the NRMS is higher than 2.0, a positive response is defined and the concentration of DEX will be added by 0.05µg/kg/h in the next patient. A negative response is defined as NRMS lower than 2.0, and in such cases the concentration of DEX is reduced by 0.3 µg/kg/h.
