The Optimal Timing of Carbon Dioxide Insufflation During Colonoscopy in Unsedated Patients

NCT01415076 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 200

Summary

Insufflation of carbon dioxide (CO2) instead of air can reduce pain resulting from colon distension after colonoscopy because CO2 is rapidly absorbed from the colon and excreted through the lungs. This reduces the effects of colonic distension and minimizes intracolonic gas at the end of the examination. The aims of the study were to evaluate the timing of administering CO2 insufflation and to identify predictors of discomfort for colonoscopy.
