Randomized Controlled Trial Comparative Study
Efficacy of carbon dioxide versus air insufflation according to different sedation protocols during therapeutic endoscopic retrograde cholangiopancreatography: prospective, randomized, double-blind study.
Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) tends to require considerable air insufflation, which results in abdominal pain or distension. We investigated the efficacy of carbon dioxide (CO2 ) compared with air insufflation when using two different sedation protocols in therapeutic ERCP. ⋯ CO2 with BPS showed the lowest VAS score for early abdominal pain, distension and GVS, and had a higher score for overall satisfaction for sedation.
