Randomized Controlled Trial Comparative Study
[Comparison between insufflation with air or carbon dioxide during the colonoscopy in sedated patients with propofol].
compare the intensity of pain experienced after colonoscopy with air or with CO₂ and evaluate the safety of CO₂ in colonoscopies performed with moderate/deep sedation. ⋯ a) the use of CO₂ in colonoscopy causes significantly less pain in the first 6 hours after the procedure; b) its use in patients with moderate/deep sedation is safe; and c) performance of the endoscopic technique is not modified, nor are times reduced.
