Procedural sedation is widely administered by a variety of practitioners to facilitate painful or frightening procedures in children.1-9 Guidelines9 recommend a minimum period of fasting (nothing by mouth) prior to elective sedation because of concerns about pulmonary aspiration.7-9 These guidelines most commonly mirror thresholds fixed for elective general anesthesia: 2 hours or longer for clear liquids, 4 hours or longer for breast milk, and 6 hours or longer prior for cow milk, infant formula, or a light meal.9
