Two randomized controlled trials and one large prospective cohort study reported on aspiration and regurgitation.99101 One trial reported no aspiration in either group.99 The other trial included children undergoing surgery for cyanotic congenital heart disease and did not detect a difference in aspiration; however, incidence was high in this population (1.8 and 1.7% in the 1- and 2-h arms respectively).100 A large prospective cohort study that included subgroups of children fasting less than 1h (n = 1,709) and 1 to 2h (n = 2,897) reported higher rates of aspiration and regurgitation in the less than 1-h fasting group (very low strength of evidence) but also noninferiority for regurgitation or pulmonary aspiration (not worse than 1 per 1,000) for a 1- to 2-h clear liquid fast compared with longer times.101. The consultants and ASA members both disagree that preoperative antiemetics 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. Preoperative Fasting - The National Institute for Health and Care . 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. A meta-analysis of three trials found a difference of 2.5ml (95% CI, 8.6 to 3.7) in residual gastric volume for protein-containing clear liquids versus fasting.49,68,91.

The guidelines do not address the selection of anesthetic technique, nor do they address enhanced recovery protocols not designed to reduce the perioperative risk of pulmonary aspiration. Omeprazole reduces preoperative gastric fluid acidity and volume in children. Two combined probability tests were employed as follows: (1) the Fisher combined test, producing chi-square values based on logarithmic transformations of the reported P values from the independent studies, and (2) the Stouffer combined test, providing weighted representation of the studies by weighting each of the standard normal deviates by the size of the sample.

Preoperative oral carbohydrate reduces postoperative insulin resistance by activating amp-activated protein kinase after colorectal surgery. Differences were not detected in patient-reported hunger or thirst, incidence of aspiration or regurgitation, and gastric pH among pediatric patients fasting for 1h compared with 2h (table 7). * The interventions listed in the evidence model below were examined to assess their impact on outcomes related to perioperative pulmonary aspiration. For example, a rapid-sequence induction/endotracheal intubation technique or awake endotracheal intubation technique may be useful to prevent this problem during the delivery of anesthesia care. Studies with multicomponent interventions (for example, enhanced recovery after surgery protocols) were excluded if the effect of fasting on outcomes could not be independently ascertained. Any benefits of gum chewing are inconsistent and insufficiently studied to encourage gum chewing before surgery.
