Preoperative carbohydrate nutrition reduces postoperative nausea and vomiting compared to preoperative fasting. However, studies in children are limited, lack significant power to detect uncommon risks, and clinical controversy exists.117, There is a need for well designed, adequately powered randomized trials or large prospective cohort studies in both adults and children to evaluate uncommon adverse events and patient-reported outcomes including preoperative thirst, hunger, anxiety, and patient satisfaction.

Effect of routine preoperative fasting on residual gastric volume and acid in patients undergoing myomectomy. In addition, practice guidelines developed by the American Society of Anesthesiologists (ASA) are not intended as standards or absolute requirements, and their use cannot guarantee any specific outcome.

Prevention or reduction of perioperative pulmonary aspiration. No differences in the occurrence of regurgitation were detected. Decision-making is complicated by emerging data suggesting that some of the conditions traditionally considered to have an impact on gastric emptying may have little or no effect on gastric emptying. Patients with conditions that can affect gastric emptying or fluid volume. Parents understanding of and compliance with fasting instruction for pediatric day case surgery. First, the Task Force reached consensus on the criteria for evidence. Since nonhuman milk is similar to solids in gastric emptying time, consider the amount ingested when determining an appropriate fasting period. Category A evidence represents results obtained from randomized controlled trials (RCTs) and Category B evidence represents observational results obtained from nonrandomized study designs or RCTs without pertinent comparison groups. Industry support was reported in 16 trials, and author conflict of interest was reported in 12 (10%) studies. The effect of shortening the pre-operative fluid fast on postoperative morbidity. 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.

Preoperative oral carbohydrate treatment attenuates immediate postoperative insulin resistance. An RCT comparing a light breakfast consumed less than 4 h before a procedure with overnight fasting reports equivocal findings for gastric volume and pH levels for adults (Category A3-E evidence).47 A second RCT reports equivocal findings when a light breakfast is allowed at 4 h compared with 6 h before a cesarean section (Category A3-E evidence), although a significant reduction in maternal and neonatal blood glucose levels was reported when fasting was extended beyond 6 h (Category A3-H evidence).48 Nonrandomized comparative studies for children given nonhuman milk 4 h or less before a procedure versus children fasted for more than 4 h report equivocal findings for gastric volume and pH (Category B1-E evidence).4951 One nonrandomized study indicated that fasting for more than 8 h may be associated with significantly lower blood glucose levels (Category B1-H evidence).51 The literature is insufficient to evaluate the effect of the timing of ingestion of solids and nonhuman milk and the perioperative incidence of pulmonary aspiration or emesis/reflux. 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). The consultants agree and the ASA members strongly agree that fasting from the intake of a light meal (e.g., toast and a clear liquid) of 6 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained.

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.

Level 2: The literature contains noncomparative observational studies with associative statistics (e.g., relative risk, correlation, sensitivity and specificity). The ASA members disagree and the consultants strongly disagree that preoperative anticholinergics should be routinely administered before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia to decrease the risk of pulmonary aspiration. Meta-analysis of placebo-controlled RCTs indicate that metoclopramide is effective in reducing gastric volume and pH during the perioperative period (Category A1-B evidence).5560 The literature is insufficient to evaluate the effect of metoclopramide on the perioperative incidence of pulmonary aspiration.***. These guidelines are intended for use by anesthesiologists and other anesthesia providers.
