Available evidence suggests that the use of CO(2) insufflation in endoscopy is more comfortable for the patient. The safety of CO(2) use in colonoscopy remains contentious, particularly in sedated patients. The objective of the present prospective trial was to assess the safety of CO(2) colonoscopies. Methods. 109 patients from our previous randomized CO(2) colonoscopy study and an additional 238 subsequent consecutive unselected patients who had a routine colonoscopy performed in a private practice were enrolled from April 2008 through September 2008. All but 2 patients were sedated. All patients were routinely monitored with transcutaneous CO(2) measurement. Volumes of CO(2) administered were correlated with capnographic measurements from transcutaneous monitoring. Results. Of the 347 patients examined, 57% were women; mean (SD) age of participants was of 60.2 years (12.8). Mean propofol dosage was 136 mg (64 mg). Mean CO(2) values were 34.7 mm Hg (5.3) at baseline, 38.9 mm Hg (5.5) upon reaching the ileum, and 36.9 mm Hg (5.0) at examination's end. Mean maximum increase of CO(2) was 4.5 mm Hg (3.6). No correlation was observed between volume of CO(2) administered and increase in level of CO(2) (correlation coefficient: 0.01; P value: 0.84). No complications were observed. Conclusions. The present prospective study, which was based on one of the largest sedated patient sample reported to date in this setting, provides compelling evidence that CO(2) insufflation in colonoscopy is safe and unassociated with relevant increases in transcutaneously measured levels of CO(2).
