Randomized Controlled Trial Clinical Trial
Can visual distraction decrease the dose of patient-controlled sedation required during colonoscopy? A prospective randomized controlled trial.
We previously demonstrated that audio distraction using relaxation music could lead to a decrease in the dose of sedative medication required and improve patient satisfaction during colonoscopy. This prospective randomized controlled trial was designed to test the hypotheses that visual distraction may also decrease the requirement for sedatives and that audio and visual distraction may have additive beneficial effects when used in combination. ⋯ Visual distraction alone did not decrease the dose of sedative medication required for colonoscopy. When audio distraction was added, both the dose of sedative medication required and the pain score decreased significantly. Both visual and audiovisual distraction might improve patients' acceptance of colonoscopy.
