Outcome Measures

Primary Outcomes (1)

  • Bilateral BIS values at return of consciousness in patients with and without supratentorial brain tumor.

    one year

Secondary Outcomes (1)

  • 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
