Primary Outcome Measures:
  • administered dose of propofol during maintenance of anesthesia [ Time Frame: day 1 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • administered dose of propofol during induction of anesthesia [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • administered doses of remifentanil during induction and maintenance of anesthesia [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • delay (measured as minutes) between the end of propofol and remifentanil administration and the recovery from anesthesia [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • hemodynamic abnormalities requiring treatment [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • % of time with a BIS index between 40 and 60 [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • postoperative morphine requirement [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • incidence of postoperative nausea and vomiting [ Time Frame: day 1 ] [ Designated as safety issue: No ]
  • % of patients with an explicit memorisation of the intraoperative period [ Time Frame: second postoperative day ] [ Designated as safety issue: No ]
