Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Colon cancer is the second most common cancer in men and the third most common cancer in women worldwide. The clinical objectives of administering sedation for GI endoscopy are to relieve patient anxiety and discomfort and to improve the outcome of the examination. Use of N2O could potentially provide an alternate safe and cheap option for patients who do not prefer IV sedation for colonoscopy
