The purpose of this study is to determine whether a non-pharmacological intervention reduces consumption of sedative drugs during colonoscopy. A reduction of sedative drugs may reduce side effects. This non-pharmacological intervention may increase patient's comfort and security.

Arms Assigned Interventions
Active Comparator: standard sedation
propofol and fentanyl
Drug: standard sedation
Standard sedation: fentanyl 2x0,5 microg/kg at beginning of procedure and propofol PCS: 20mg bolus than 10mg/bolus, lock-out = 0.
Other Name: Disoprivan (propofol)and fentanyl
Active Comparator: structured attention-standard sedation
structured attention
Behavioral: Structured attention
Structured attention: verbal and nonverbal communication; attentive listening; provision of the perception of control; encouragement; use of emotionally neutral descriptors, focus on a sensations.
Other Name: psychological support
Experimental: hypnosis-standard sedation
Behavioral: hypnosis
Hypnosis: induction of hypnosis by visual fixation and recollection of a pleasant memory, suggestion of relaxation, of self-control and post-hypnotic suggestion for bowel relaxation.
Other Name: hypnotic state

Detailed Description:

Sedative and analgesic drugs are used in most patients related to pain and anxiety during the colonoscopy. Analgesia and sedation has adverse effects such as central respiratory depression, obstruction of the upper airways, hypoxia, hypotension and bradycardia. Non-pharmacological interventions had beneficial effects during percutaneous vascular or renal procedures. In this study we test the hypothesis that the adjunction of hypnosis to pharmacological sedation will decrease the quantity of sedative drugs used and will reduce the patient's anxiety and discomfort.
