Randomized Trial of Diphenhydramine Versus Continued Midazolam in "Difficult-to-sedate" Patients Undergoing Colonoscopy

Summary

Patients who are undergoing colonoscopy and are not adequately sedated after initial standard sedation with midazolam 5 mg and fentanyl 100 mcg will be randomly assigned to receive diphenhydramine vs. continued midazolam, and their level of sedation will be assessed. Our hypothesis is that diphenhydramine will provide better sedation than continued administration of midazolam during colonoscopy in patients not achieving adequate sedation with standard doses of midazolam plus fentanyl.
