Abstract

Objective: To compare the level of abdominal pain between CO2 and air insufflation during colonoscopy and evaluate related factors. Methods: This cross-sectional study included 336 patients indicated for colonoscopy with anaesthesia using Propofol from August 2022 to June 2023 at the Institute of Gastroenterology and Hepatology. The patients were divided into 2 groups: one used CO2 and the other used air for insufflation during colonoscopy. We measured procedure time, cecal intubation time, withdrawal time, and pain levels evaluated by VAS score after 15 minutes, 30 minutes and 60 minutes after the procedure. Results: There were no differences between the CO2 group and the air group in procedure time, cecal intubation time, withdrawal time. There are differences of the median VAS at 30 minutes (0 vs 3,0) and at 60 minutes (0 vs 3,0) after colonscopy between the CO2 group and the air group, p<0,001. Except for the use of CO2 during colonoscopy, there are no relationship between pain after colonoscopy with age, gender, procedure time, BMI, gastrointestinal diseases, and dose of propofol. Conclusion: Using CO2 did not prolong the procedure time, cecal intubation time, withdrawal time and decreased the pain level after colonoscopy. Patients using CO2 also had lower pain levels than using air.
