Hypothesis
Does CO2 insufflation reduce pain and bloating during and after colonoscopy compared to room air?
Conclusion
CO2 insufflation significantly reduces bloating and pain after routine colonoscopy and is safe.
Supporting Evidence
- Patients with CO2 insufflation reported significantly less bloating during recovery.
- CO2 group experienced significantly less pain at multiple time points post-procedure.
- Overall satisfaction scores were higher in the CO2 group compared to the air group.
Takeaway
Using CO2 instead of air during colonoscopy makes the procedure less painful and more comfortable for patients.
Methodology
A double-blinded, randomized controlled trial comparing CO2 and air insufflation in 219 patients undergoing colonoscopy.
Potential Biases
Minimal risk of bias due to independent randomization by a study nurse.
Limitations
Imbalances in gender and IBS between groups; randomization method may introduce bias.
Participant Demographics
219 patients, with 62% female in the CO2 group and 47% female in the air group.
Statistical Information
P-Value
P < .001 for bloating; P = .014 for pain.
Statistical Significance
p<0.001
