From the patient's perspective, sedation and analgesia are two of the most important issues linked to procedure satisfaction. Considering that success of colonoscopy as a screening exam relies on serial evaluations at least every 10 years, a patient's avoidance of pursuing repeat evaluations due to prior bad experiences can lead to potential premalignant lesions or other disease going undetected and advancing to more serious disease. Sedation, analgesia, and patient monitoring in endoscopy are covered in greater detail in another chapter of this text. In general, the use of a benzodiazepine (midazolam or diazepam) in combination with analgesia (meperidine or fentanyl) provides adequate conscious sedation for lower endoscopy. These agents work synergistically in providing sedation while the benzodiazepine provides an added amnestic effect. However, in some instances, deeper sedation may be needed. Propofol or even general anesthesia can be used for these patients.
