Parkinson's disease is a common progressive degenerative disease affecting 3% of all patients over the age of 65. Given their age and frailty, these patients frequently require surgical procedures with general anesthesia. However, after surgery, patients with Parkinson's disease have longer hospital stays and a greater chance of not returning to independent living compared to age-matched controls (Berman MF, unpublished data). In part, this is due to a higher rate of post-operative delirium, which had an incidence of 60% in this population in one study. There is anecdotal evidence from neurologists specializing in movement disorder suggesting that there is also significant deterioration in parkinsonian motor symptoms and cognition lasting for months or years following surgery and anesthesia. The basis for this deterioration is unknown. We hypothesize that these problems are caused by particular medications used during inhaled anesthesia for surgical procedures.

Enrollment: 0
Study Start Date: October 2003
Study Completion Date: April 2011
Primary Completion Date: April 2010 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Isoflurane
    Group 1 Inhaled anesthesia Patients maintained on 50% oxygen in air and isoflurane 0 to 4%, titrated as needed to maintain a standard blood pressure (standard practice). If needed, muscle relaxation provided by additional boluses or an infusion of mivacurium (410 ug/kg/min).
    Drug: Propofol and Remifentanil
    Group 2 Intravenous anesthesia Patients ventilated with 50% oxygen in air. Patients receive continuous propofol infusion 0.05 mg/kgmin to 0.15 mg/kgmin titrated as needed; and remifentanil (ultrashort acting narcotic) 0.1 ug/kgmin to 0.5 ug/kgmin. Titration as needed to maintain a standard blood pressure. Both infusions turned off at the end of the procedure. If needed, muscle relaxation provided by additional boluses or an infusion of mivacurium (410 ug/kg/min).
