What is the purpose of using carbon dioxide during colonoscopy?

The use of carbon dioxide during colonoscopy primarily serves the purpose of insufflating the colon more comfortably and reducing post-procedural pain. Carbon dioxide is preferred because it is absorbed more quickly by the body compared to air. This quick absorption helps lessen the discomfort and cramping that patients may experience after the procedure, which is often associated with air insufflation.

By providing a more comfortable experience, carbon dioxide can improve patient tolerance of the procedure, potentially leading to increased compliance and satisfaction. This practice aligns with the goal of reducing postoperative discomfort and improving overall patient outcomes during and after a colonoscopy.

The other purposes listed do not accurately represent the main benefits of using carbon dioxide in this context. While visibility of the mucosa is important, the use of carbon dioxide does not directly contribute to enhanced visibility compared to other methods or gases. Likewise, while effective timelines in procedures are important, the primary function of carbon dioxide is not to speed up the procedure itself but rather to enhance patient comfort. Additionally, its role in aiding the healing process is not a primary reason for its use during colonoscopy.
