Decreased discomfort after colonoscopy is a high priority for patients. Typically, air is used to insufflate the bowel during colonoscopy, but emerging literature shows that carbon dioxide insufflation decreases postoperative discomfort and flatus. An evidence-based practice project was developed and implemented by a surgical department at a community hospital. The Director of Surgical Services brought the evidence to the staff, secured agreement from a physician champion, and the new process was quickly adopted. Patients experienced less discomfort and flatus postprocedure with carbon dioxide insufflation, and were able to be discharged expediently. These patient outcomes validated the literature and confirmed the success of the practice change.
