Primary Outcome Measures:
  • administered doses of propofol and of remifentanil during anesthesia [ Time Frame: end of anesthesia ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • delay before recovery [ Time Frame: at the end of anesthesia ] [ Designated as safety issue: No ]
  • hemodynamic abnormalities requiring a treatment [ Time Frame: end of anesthesia ] [ Designated as safety issue: No ]
  • postoperative morphine requirement [ Time Frame: Third post-anesthetic hour ] [ Designated as safety issue: No ]
  • explicit memorisation [ Time Frame: Second postoperative day ] [ Designated as safety issue: No ]
