CO 2 vs. air insufflation in endoscopic ultrasonography: a prospective study.

ABSTRACT: Background and study aims  Carbon dioxide (CO 2 ) is being increasingly used for insufflation during endoscopy for safety and better tolerance. The role of CO 2 during endoscopic ultrasonography (EUS) has not been studied yet. Our main aim was to compare the effects of CO 2 vs. air insufflation on abdominal discomfort in patients undergoing EUS. Our secondary outcomes were to ascertain the effects of CO 2 insufflation on image quality/visual artifacts and on the amount of sedation. Patients and methods  This was a prospective, controlled, single-blind, observational study. Abdominal discomfort was assessed before diagnostic EUS, and 1 and 3 hours post-procedure and recorded as a visual analogue scale. Image quality was also recorded as a 4-point scale from optimal to poor at four different
