Randomized Controlled Trial Comparative Study Clinical Trial
Patient-controlled sedation for colonoscopy: a randomized trial comparing patient-controlled administration of propofol and alfentanil with physician-administered midazolam and pethidine.
Patient-controlled sedation (PCS) using propofol and alfentanil provides effective sedation for colonoscopy, with the advantage of a shorter recovery time in comparison with diazepam and pethidine. However, most endoscopy units in the United Kingdom are currently using midazolam (a shorter-acting benzodiazepine) as a sedative agent. This study compares the efficacy of sedation and recovery times between PCS and a combination of midazolam and pethidine. ⋯ PCS provides an acceptable alternative to sedation with midazolam and pethidine with the advantage of significantly faster recovery times, which are of relevance in the outpatient setting.
