Analgesic effect of premedication with meperidine in patients undergoing colonoscopy without sedation

Conclusion In our study, premedication with meperidine or no premedication was not associated with a reduction in abdominal pain during colonoscopy without sedation. The insertion time and cecal intubation rate showed no difference between patients with or without additional analgesic drugs prior to the procedure. However, as self-selection bias could not be ruled out, further randomized, placebo-controlled trials are needed to confirm our findings.
