Intervention group 2: Dexmedetomidine infusion 1 micg/kg/ min for 10 min and then 0.5 micg/kg/h to the end of surgery.
Primary outcome: Measuring bleeding at 1, 5, 15, 30 and 60 minutes after starting infusion using suction.
Randomization: The patients will be randomly assigned to intervention and control groups using block randomization.
