Further study details as provided by Hopital Foch:

Primary Outcome Measures:
  • administered doses of propofol and of remifentanil during anesthesia [ Time Frame: end of anesthesia ]

Secondary Outcome Measures:
  • delay before recovery [ Time Frame: at the end of anesthesia ]
  • hemodynamic abnormalities requiring a treatment [ Time Frame: end of anesthesia ]
  • postoperative morphine requirement [ Time Frame: Third post-anesthetic hour ]
  • explicit memorisation [ Time Frame: Second postoperative day ]

Enrollment: 15
Study Start Date: June 2009
Study Completion Date: December 2011
Primary Completion Date: December 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo
patients will receive a closed-loop administration of propofol and remifentanil according to bispectral level and a placebo
Drug: NaCl 9/00
