Using carbon dioxide (CO2) for colonoscopy insufflation significantly reduces post-procedure discomfort compared to air. Patients experienced less pain and bloating, leading to greater overall comfort with CO2.
Area of Science:
- Gastroenterology
- Medical Devices
- Patient Outcomes
Background:
- Colonoscopy is increasingly common in Brazil for screening and therapeutic procedures.
- Patient comfort and experience are crucial aspects of endoscopic procedures.
Purpose of the Study:
- To compare the efficacy and patient-reported outcomes of carbon dioxide (CO2) versus air insufflation during colonoscopy.
Main Methods:
- A double-blind, randomized study involving 210 eligible patients.
- Patients were allocated to either the Air Group (n=104) or CO2 Group (n=97).
- Data collected included patient demographics, procedural details, and post-procedure pain and bloating assessments.
Main Results:
- No significant differences were observed between groups regarding bowel preparation, age, gender, surgical history, or procedural maneuvers.
- Post-procedure pain and bloating were more prevalent in the Air Group.
- Patients reported greater comfort and less bloating when CO2 was used for insufflation.
Conclusions:
- Carbon dioxide (CO2) insufflation offers superior patient comfort compared to air during colonoscopy.
- CO2 insufflation effectively mitigates post-examination bloating, enhancing the overall patient experience.
