Comparison Between Two Different Dosages of Remifentanil During Colonoscopy
The purpose of this randomized double-blind trial is to define the correct dosage of Remifentanil during operative and diagnostic endoscopic procedures. In particular we want to analyze if the administration of Remifentanil by PCSA (Patient Controlled Sedation and Analgesia) is a good method during colonoscopy, evaluating pain control, discharge time and side effects.
90 patients undergoing colonoscopy will be enrolled.

- Discharge Time, the Time to Reach a Modified Aldrete Score ≥18 [ Time Frame: > 0 minutes ] [ Designated as safety issue: No ]Ten key parameters (Activity, Respiration, Circulation, Consciousness, O2 Saturation, Dressing, Pain, Ambulation, Fasting-feeding, Urine Output)are included in the Modified Aldrete Score. The maximum and minimum score for each parameter is respectively 2 and 0. The maximum total score is 20 and patient can be discharged when the total score is ≥18.
- Patient's Satisfaction [ Time Frame: After the end of colonoscopy (when patients were completely awake) and 24 h after the procedure via telephone ] [ Designated as safety issue: No ]The degree of satisfaction about the quality of sedation was measured with VAS (Visual Analog Scale) where 0 means no satisfaction and 100 means maximum satisfaction.

|Experimental: Remifentanil RS1||
Patient receive a bolus of Remifentanil (0,5 mcg/Kg) before the procedure and the PCSA pump is set to inject further bolus doses of 0,5 mcg/Kg every time the patient presses its button.
|Experimental: Remifentanil RS2||
Patient receive a bolus of Remifentanil (0,8 mcg/Kg) before the procedure and the PCSA pump is set to inject further bolus doses of 0,8 mcg/Kg every time the patient presses its button.
|Active Comparator: Meperidine||
Patient receive a bolus of Meperidine (0,7 mg/Kg) before the procedure and the PCSA pump with saline (sham PCSA) is connected.
