Effects of Propofol on Brain Function in Patients With Parkinson's Disease
Recruiting now
Conditions studied: PD - Parkinson's Disease
In brief
Propofol is a short-acting general anesthetic drug commonly used in clinical practice, with rapid clinical onset of action, amnesic, anxiolytic, antiepileptic, and muscle relaxant effects. The lack of natural antioxidants in patients with Parkinson's disease and propofol's ability to protect the brain by inhibiting oxidative stress, its pharmacokinetic and pharmacodynamic properties make propofol a suitable anesthetic drug for functional stereotactic surgery in patients with Parkinson's disease. However, changes in brain functional status during propofol anesthesia in Parkinson's patients are unknown. There is a lack of data from extensive clinical studies to support the need for propofol dosing during induction of anesthesia compared with non-Parkinson patients. This study is a prospective cohort study designed to compare the differences in propofol dosing requirements during induction of propofol anesthesia in patients with PD versus non-PD and to monitor the characteristics of altered brain functional status such as EEG and cerebral blood flow autoregulation capacity in PD versus non-PD patients during the perioperative period.
