Further study details as provided by Assistance Publique - Hôpitaux de Paris:

Primary Outcome Measures:
  • Percentage of patients who have well tolerated the colonoscopy as assessed by visual analogic scale (>75/100) [ Time Frame: Immediately after the colonoscopy ]
  • The mean grade of patient anxiety before endoscopy [ Time Frame: After the colonoscopy ]
    The mean grade of patient anxiety before endoscopy

Secondary Outcome Measures:
  • The mean tolerability of the colonoscopy between the group with sedation by nitrous oxide/oxygen mixture and the group with anesthesia [ Time Frame: after the colonoscopy ]
  • The mean pain intensity during the procedure on a visual analogic scale [ Time Frame: after the colonoscopy ]
  • The mean patient satisfaction on a visual analogic scale. [ Time Frame: after the colonoscopy ]
  • The percentage of patients who agree to repeat the procedure in similar circumstances. [ Time Frame: after the colonoscopy ]
  • The grade of difficulty of the colonoscopy evaluated by the endoscopist [ Time Frame: After the colonoscopy ]
  • The mean duration of the endoscopy [ Time Frame: After the colonoscopy ]
  • The percentage of caecum intubation [ Time Frame: After the colonoscopy ]
  • The percentage of ileal intubation [ Time Frame: After the colonoscopy ]
  • The opinion of the endoscopist on the tolerance of the colonoscopy [ Time Frame: After the colonoscopy ]
  • The time to hospital discharge [ Time Frame: After the issue of the colonoscopy ]
  • The Aldrete's score at the hospital discharge [ Time Frame: After the colonoscopy ]
  • The number of patient who have refused the inclusion [ Time Frame: After the issue of the colonoscopy ]

Enrollment: 220
Study Start Date: February 2009
Study Completion Date: January 2011
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: MEOPA
MEOPA : equimolar nitrous oxide/oxygen mixture
anaesthetic gaz inhalation
Other Name: anaesthetic gaz inhalation
Active Comparator: General anesthesia
Gold standard
Drug: general anaesthesia
Anaesthetic intravenous route
Other Name: Anaesthetic intravenous route

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.
