Comparison of propofol-nalbuphine and propofol-fentanyl sedation for patients undergoing endoscopic retrograde cholangiopancreatography: a double-blind, randomized controlled trial

Abstract

Abstract Background Endoscopic retrograde cholangiopancreatography (ERCP) has been increasingly used to treat patients with biliary/pancreatic duct obstruction or stricture outside the operating room. Effective and safe sedation techniques are needed because of painful stimuli and the long duration of the ERCP procedure.Nalbuphine has been shown to cause less respiratory depression during sedation than similar cases without nalbuphine. This study compared the effects of propofol-nalbuphine (PN) and propofol-fentanyl (PF) sedation in patients undergoing ERCP. Methods Four hundred patients scheduled for ERCP procedures were divided into two groups: the PF group (receiving PF sedation,n = 199) and the PN group (receiving PN sedation,n = 201). Vital signs, adverse events during surgery, patient movement scores, pain scores, and adverse events one day post-ERCP were recorded. Results Stable haemodynamics were observed in both groups.Compared to the PF group, the PN group showed significantly decreased respiratory depression (P < 0.0001) and surgical interruptions (P = 0.048).Nalbuphine decreased patient movement by reducing pain from ERCP. Conclusion Nalbuphine, instead of fentanyl, precipitated less respiratory depression while permitting adequate/equivalent sedation for ERCP and therefore provides more efficient and safer sedation.
