Study 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.

Primary Outcome

Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scale. This scale ranges from 0 to 5, where 0 denotes general anesthesia, in which the patient has no response to painful stimuli, and 5 denotes a level of minimal sedation in which the patient is fully awake.

Interventions

  • DRUG Midazolam
  • DRUG Diphenhydramine
