Randomized comparison of recovery time after use of remifentanil alone versus midazolam and meperidine for colonoscopy anesthesia

摘要

Background and AimAlthough the combination of midazolam-meperidine has been widely used as a sedation regimen for colonoscopy, its residual effect which is longer than the duration of a colonoscopy procedure can delay patient recovery and discharge. Remifentanil, an ultra-short-acting opioid, has a very brief duration of action. We hypothesized that using remifentanil alone for colonoscopy would provide shorter recovery time compared with the midazolam-meperidine combination.
