Randomized Controlled TrialPatient-controlled analgesia and sedation with alfentanyl versus fentanyl for colonoscopy: a randomized double blind study.
The aim of this study was to evaluate whether sedo-analgesia with alfentanyl/fentanyl, using a patient-controlled analgesia (PCA) pump, may have positive outcomes in terms of safety, postprocedural workload, and expectations of the colonoscopist, nurse, and patients in elective colonoscopy. ⋯ PCA and sedation with alfentanyl and fentanyl for colonoscopy are safe, feasible, and acceptable to most patients. However, shorter sedation times make alfentanyl more attractive for postprocedural workload.
