Compare Propofol to Fentanyl and Midazolam for Colonoscopy

Randomized Trial to Compare Propofol to Fentanyl and Midazolam for Colonoscopy.

The study aim is to determine if Propofol or the combination of Fentanyl and low-dose Midazolam, are equivalent for patient satisfaction and discomfort when undergoing a colonoscopy. This is a prospective randomized study of 262. The primary outcome of this study is participant's satisfaction and discomfort of the colonoscopy procedure as perceived by the participant, and the secondary outcome will be the discomfort of the patient and difficulty of the procedure as perceived by the physician.

Background The use of colonoscopy has become an important diagnostic and therapeutic tool in the evaluation of multiple medical conditions of the gastrointestinal tract. Despite its widespread use, there continues to be debate concerning the best pharmacologic approach to patient satisfaction and discomfort of the procedure and to minimize side effects.

Aim Two standard pharmacologic (Propofol or Fentanyl and low-dose Midazolam) approaches for colonoscopy will be evaluated systematically to determine if these two approaches are equivalent in terms of patient rating of satisfaction and patient discomfort to the procedure and side effects

Study Design This is a prospective randomized study of 262 participants undergoing outpatient colonoscopy at an independent academic medical center. The primary outcome of this study is participant's satisfaction, and the secondary outcome is discomfort of the patient as perceived by the physician performing the procedure.
