Can examination of lower bowel by flexible telescope be made easier for patients by showing them a video about it and laughing gas to breathe?

Phase 4

Completed

• Conditions: colonic lesions; Rectal bleeding; Oral and Gastrointestinal - Other diseases of the mouth, teeth, oesophagus, digestive system including liver and colon

• Registration Number: ACTRN12621000918820
• Lead Sponsor: Philip Bagshaw

Brief Summary

The study showed that a pre-procedure familiarization video did not make an examination of the lower bowel by an endoscope, without pain relief or sedation, any more pleasant. However, having Entonox gas to breathe during the procedure did improve the experience and made it possible to examine a longer length of bowel. Measuring changes in heart rate can help to see how stressed patients get during such an examination.
