Primary Outcome Measures:
  • Bilateral BIS values at return of consciousness in patients with and without supratentorial brain tumor. [ Time Frame: one year ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Difference between left- and rightsided BIS values in patients with supratentorial brain tumor during course and Comparison between predicted and measured propofol plasma concentrations during course of the study [ Time Frame: one year ] [ Designated as safety issue: No ]
