Trial Outcomes & Findings for Intravenous Versus Inhalational Anesthesia in Parkinson's Disease (NCT NCT00615472)

NCT ID: NCT00615472

Last Updated: 2015-07-13

Results Overview

A battery/Questionnaire of neuropsych examinations is given to the subjects to measure improvement based on change of scores and standard deviation. The battery consists of questions regarding delirium, cognitive and motor changes and yields a combination assessment of all 3 elements.

Participant Flow

We enrolled only a few patients. Our neurocognitive battery was too hard for patients to get through. Therefore, the study was stopped.

Measure
Inhaled Anesthesia
n=30 Participants
Inhaled Anesthesia - isoflurane Isoflurane: Group 1 Inhaled anesthesia Patients will be 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 will be provided by additional boluses or an infusion of mivacurium (4-10 ug/kg/min).
Intravenous Anesthesia
n=28 Participants
Intravenous Anesthesia - propofol, remifentanil Remifentanil: Group 2 Intravenous anesthesia Patients will be ventilated with 50% oxygen in air. Patients will receive continuous propofol infusion 0.05 mg/kg-min to 0.15 mg/kg-min titrated as needed; and remifentanil (ultra-short acting narcotic) 0.1 ug/kg-min to 0.5 ug/kg-min. Propofol: Group 2 Intravenous anesthesia Patients will be ventilated with 50% oxygen in air. Patients will receive continuous propofol infusion 0.05 mg/kg-min to 0.15 mg/kg-min titrated as needed
