Summary Background There is little evidence to guide choice between meperidine (pethidine) and fentanyl for sedation for gastrointestinal endoscopy. Aim To compare meperidine with fentanyl in terms of procedure time and analgesia. Methods Single centre randomized controlled trial. Patients received narcotic doses and midazolam at the discretion of the attending endoscopist who was unaware of narcotic assignment. Endoscopy and recovery times were then recorded. The main outcome was total procedure time, defined as endoscopy time plus recovery time. Patient discomfort was assessed prior to discharge via visual analogue scale (VAS). Results In total, 55 patients were randomized to meperidine [44 colonoscopy and 11 esophagogastroduodenoscopy (EGD)] and 56 to fentanyl (45 colonoscopy and 11 EGD). Total procedure time was shorter for those receiving fentanyl (mean = 87.7 min) than for those receiving meperidine (mean = 102.9 min) ( P = 0.05). The difference between the groups was explained by a shorter mean recovery time in the fentanyl group (63.0 min) than in the meperidine group (76.2 min) ( P = 0.07). Based on post procedure pain scores, examinations with meperidine (mean = 1.99) were less painful when compared with those receiving fentanyl (mean = 2.86, P = 0.03). Conclusions Fentanyl shortened total procedure time by reducing recovery time. A simple change in narcotic choice could increase endoscopy unit efficiency.
