For pediatric patients undergoing elective procedures with general anesthesia, regional anesthesia, or procedural sedation, what are the benefits and harms of 1-h versus 2-h clear liquid fasting? Although controlled studies do not sufficiently evaluate such relationships, the reported evidence does focus on intermediate outcomes, including gastric contents (e.g., volume or pH) and nausea and vomiting, typically considered by the authors to be representative of a predicted risk of pulmonary aspiration. In addition, both the consultants and ASA members strongly agree that verification of their compliance with the fasting requirements should be assessed at the time of the procedure.
