Arm Intervention/treatment
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
Same volume as in the dexmedetomidine group

Experimental: dexmedetomidine
patients will receive a closed-loop administration of propofol and remifentanil according to bispectral level and dexmedetomidine
Drug: dexmedetomidine
1 mcg/kg administered in 10 minutes followed by a continuous infusion of 0,5 mcg/kg/hr

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

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