Randomized Controlled Trial Comparative Study Clinical TrialPatient-controlled analgesia for conscious sedation during endoscopic retrograde cholangiopancreatography: a randomized controlled trial.
Adequate comfort is essential to patients undergoing invasive procedures. This study was designed to evaluate whether patient-controlled analgesia could improve sedation for ERCP. ⋯ This trial demonstrates that patient-controlled analgesia during ERCP is as effective as standard sedation with respect to patient satisfaction. Physicians and nurses, however, are not good proxies for assessing patient satisfaction.
