Whether patient-maintained sedation (the patient controls his/her degree of sedation using a hand-held device) using the drug propofol is safer and more effective when using deteriorating reaction time as an added safeguard against the small potential for over sedation in a group of healthy volunteers.

Further study details as provided by University of Glasgow:

Primary Outcome Measures:
  • Minimal Sedation Level obtained (modified Objective Observer's Assessment of Sedation)
  • Maximal change in oxygen saturation (SpO2)

Secondary Outcome Measures:
  • The maximal effect site concentration of propofol at which the minimal sedation level and maximal change in oxygen saturation were achieved
  • Relationship between reaction time, sedation level and effect site concentration of propofol
  • Requirement for supplementary oxygen (if SpO2 < 90%)
  • Requirement for airway or ventilatory support
  • Maximal change in heart rate (HR), respiratory rate (RR) and blood pressure (BP)
  • Volunteer satisfaction and recollection

Estimated Enrollment: 20
Study Start Date: May 2006
Study Completion Date: September 2006
Primary Completion Date: September 2006 (Final data collection date for primary outcome measure)
