This article is featured in This Month in Anesthesiology, page 1A. Inadequate literature cannot be used to assess relationships among clinical interventions and outcomes because a clear interpretation of findings is not obtained due to methodological concerns (e.g., confounding of study design or implementation) or the study does not meet the criteria for content as defined in the Focus of the guidelines. Medications that block gastric acid secretion may be preoperatively administered to patients at increased risk of pulmonary aspiration. The consultants and ASA members both disagree that preoperative antacids should be routinely administered before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia in patients with no apparent increased risk for pulmonary aspiration. The evidence comparing fasting with protein-containing clear liquids in adults was limited to single trials for each patient-reported outcome (table 4). Comprehensive bibliographic database searches were conducted by a medical librarian using PubMed, EMBASE, and SCOPUS in July 2020 and updated in December 2021.

The strength may be upgraded if the effect is large, if a dose-response is present, or if unaccounted residual confounding would likely have increased the effect.18 For the comparisons of simple and complex carbohydratecontaining clear liquids (residual gastric volume and hunger, and thirst), the strength of evidence was assessed with the Confidence in Network Meta-Analysis tool.19 This tool includes considerations specific to network meta-analyses.

The task force reaffirms the 2017 recommendations for clear liquids until 2h preoperatively.1 Simple or complex carbohydratecontaining clear liquids appear to reduce patient hunger when compared with noncaloric clear liquids. Sixth, the consultants were surveyed to assess their opinions on the feasibility of implementing the updated guidelines. Three (30%) studies enrolled patients rated with ASA Physical Status I or II, and 1 (10%) study included ASA Physical Status I to III (6 [60%] studies did not report ASA Physical Status). Although the relationship between gastric volume and gastric emptying time with aspiration risk has not been demonstrated in adequately powered studies,7 most published studies have used these measures as intermediate outcomes.
