Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients scheduled for colonoscopy will be devided into two groups to receive either sedation by propofol infusion or by combined dexmedetomidine and lidocaine.
(A) propofol infusion at dose 25-75 ug/kg/min, Lidocaine infusion 1-2 mg/kg/hour and Dexmedetomidine infusion 0.2-0.5 ug/kg/min, all the infusions will start just before the beginning of the procedure.
(B) Drugs will be administered all-through the duration of the procedure
(C) Drugs will be administered by intravenous infusion
(D) The primary anesthesiologist ( the anesthesiologist who planned the methodology ) will be responsible for administration.
(E) The group who will receive lidocaine and Dexmedetomidine will be the intervention group

patient satisfaction by the procedure and sedation.
It will be assessed by a scale from 0 to 10 where 0 means not at all satisfied and 10 means maximally satisfied.
patient will be asked to give the scale score once he/she is fully awake.
Patient satisfaction is a composite primary outcome
