A General Anesthesia Regimen for DBS Surgery in Patients With PD

Throughout the first and third stages of surgery, all patients receive a traditional induction of anesthesia. Fifteen minutes before the second stage of surgery (MER and clinical assessment), when the burr hole is ready, the propofol and sevoflurane infusion is discontinued, and patients receive 0.5\~1ug/kg/min remifentanil combined with 0.2\~0.5mg/kg/h esketamine. On completion of the second stage of surgery, the interventional drug is discontinued and propofol combined with sevoflurane is resumed until the end of the third stage.
