When relevant, decision-informative, and practicable, pairwise and network random-effects meta-analyses of randomized controlled trials were conducted.10,11 Nonrandomized studies were considered in the assessment of harms when there was infrequent reporting of harms in randomized controlled trials. Application to Healthy Patients Undergoing Elective Procedures: An Updated Report by the American Society of Anesthesiologists Committee on .

(Chair). Differences were not detected in vomiting99,100 or gastric pH99 between children fasted 1h versus 2h (low and very low strength of evidence, respectively). Therefore, there is insufficient evidence to recommend protein-containing over other carbohydrate-containing or noncaloric clear liquids.

Although aspiration is uncommon in healthy ASA Physical Status I or II patients (estimated 1.1/10,000 adults and 1.3/10,000 children),24 it may lead to pneumonitis, pneumonia, and airway obstruction.5,6 Of the aspiration events described in the 2021 ASA Closed Claims analysis of aspiration of gastric contents events, 57% of aspiration incidents resulted in death, and another 15% resulted in permanent severe injury.4 The rationale for preoperative fasting is to minimize gastric content, thereby lowering the risk of regurgitation and subsequent pulmonary aspiration.
