This is a Phase 3 open-label, single-arm study designed to evaluate the safety of AQUAVAN following pretreatment with an analgesic, fentanyl, in patients who are undergoing minor surgical procedures that require minimal-to-moderate sedation. All patients will be placed on supplemental oxygen via nasal cannula and an electrocardiogram monitor, pulse oximeter, and blood pressure monitor will be attached prior to administration of fentanyl. Assessments will be made to evaluate the safety of AQUAVAN in patients undergoing minor surgical procedures.
