Brief summary
The aim of this study was to compare the analgesia provided by nitrous oxide/oxygen sedation or general anesthesia for colonoscopy
Detailed description
The purpose of this protocol is to compare two methods of analgesia/sedation for colonoscopy. Sedation and analgesia induced by a 50% nitrous oxide/oxygen mixture could sufficient to allow the practice of colonoscopy instead of general anesthesia which is accompanied with certain risks and post procedure drowsiness.
