Anesthesiology 2023; 138:132151 doi: https://doi.org/10.1097/ALN.0000000000004381. Both the consultants and ASA members agree that for infants, fasting from the intake of nonhuman milk for 6 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained. Studies enrolled a median of 75 participants (range, 9 to 237). The task force was responsible for developing key questions; the relevant patient populations, interventions, comparators, and outcomes; and the study inclusion/exclusion criteria to guide the systematic review (see Systematic Review Protocol in the Supplemental Digital Content, https://links.lww.com/ALN/C930). Potential inclusionexclusion discrepancies were also examined with an artificial intelligence tool, a component of the systematic review software.

We further suggest not to delay surgery in healthy adults after confirming removal of chewed gum. The intended population for this update is the same as for the 2017 ASA guideline, limited to healthy patients undergoing elective procedures.1 Healthy patients are those without coexisting diseases or conditions that may increase the risk for aspiration, including esophageal disorders such as significant uncontrolled reflux disease, hiatal hernia, Zenkers diverticulum, achalasia, stricture; previous gastric surgery (for example, gastric bypass); gastroparesis; diabetes mellitus; opioid use; gastrointestinal obstruction or acute intraabdominal processes; pregnancy; obesity; and emergency procedures.24 Anesthesiologists should recognize that these conditions can increase the likelihood of regurgitation and pulmonary aspiration and should modify these guidelines based upon clinical judgment. Parents understanding of and compliance with fasting instruction for pediatric day case surgery. Discordant results for residual gastric volume were reported in two trials99,100 randomizing patients to 1- and 2-h fasting.

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). Recent European115 and Canadian116 guidelines have recommended reducing clear liquid fasting to 1h in children. I'd call tobacco somewhere between a "clear" liquid and a light meal and say 4 hours. Effect of preanesthetic glycopyrrolate and cimetidine on gastric fluid pH and volume in outpatients. When significant heterogeneity was found among the studies (P< 0.01), DerSimonian-Laird random-effects odds ratios were obtained.

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 history, examination, and interview should include assessment of ASA physical status, age, sex, type of surgery, and potential for difficult airway management as well as consideration of gastroesophageal reflux disease, dysphagia symptoms, other gastrointestinal motility and metabolic disorders (e.g., diabetes mellitus) that may increase the risk of regurgitation and pulmonary aspiration. Fasting duration is often substantially longer than recommended irrespective of a 1- or 2-h clear liquid fasting policy.107112 Prolonged fasting influences patient-related outcomes (preoperative thirst, hunger, anxiety, nausea and vomiting, pain, and reduced feeling of well-being) and clinical outcomes (dehydration, electrolyte imbalance, and hypotension at induction of general anesthesia).113,114 Due to low-quality evidence, the task force was unable to make a recommendation for reducing the clear liquid fasting duration to 1h in the pediatric population. The body of evidence was first described according to study characteristics and treatment arms.
