Level 1: The literature contains a sufficient number of RCTs to conduct meta-analysis, and meta-analytic findings from these aggregated studies are reported as evidence. Both the consultants and ASA members agree that for neonates and infants, fasting from the intake of infant formula for 6 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained. They provide basic recommendations for anesthesia care that are supported by synthesis and analysis of the current literature, expert and practitioner opinion, public comment, and clinical feasibility data.

Does preoperative oral carbohydrate treatment reduce the postoperative surgical stress response in lumbar disc surgery? Supplemental digital content is available for this article. Twelve studies (53%) reported enrolling patients rated with ASA Physical Status I or II (2 studies also included ASA Physical Status III, and 9 did not report ASA Physical Status). The members disclosed relevant relationships (industry and other entities) that might pose a conflict of interest. Free dissociable IGF-I: Association with changes in igfbp-3 proteolysis and insulin sensitivity after surgery. We recommend healthy adults drink carbohydrate-containing clear liquids until 2h before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation. Preoperative fasting guidelines recommended by the American Society of Anesthesiologists (ASA ) do not allow eating or drinking, for a specific period of time before anesthesia is. The Cochrane Collaborations tool for assessing risk of bias in randomised trials. A study of preoperative fasting in infants aged less than three months. The addition of protein to preoperative carbohydrate-containing clear liquids did not seem to either benefit or harm healthy patients. Infant formula may be ingested for up to 6 h before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia. 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 Task Force notes that intake of fried or fatty foods or meat may prolong gastric emptying time.

Inform patients of fasting requirements and the reasons for them sufficiently in advance of their procedures. About Us; Staff; Camps; Scuba. Findings from these RCTs are reported separately as evidence. Effects of oral rehydration therapy on gastric volume and pH in patients with preanesthetic h2 antagonist. 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. In adults, evidence comparing fasting with chewing gum was inconsistent with respect to patient-rated hunger92 or thirst92,93 (very low strength of evidence). A carbohydrate-rich drink shortly before surgery affected IGF-I bioavailability after a total hip replacement. One study included younger children (mean age, 3 yr), 2 included children with mean or median age of 5 yr, and the remaining studies reported median ages ranging from 7 to 11 yr. Five studies were conducted in surgical settings, and 4 were nonsurgical. Effects of fasting and oral premedication on the pH and volume of gastric aspirate in children. Aspiration of gastric contents is associated with increased perioperative morbidity and mortality [ 1-3 ], with highest risk associated with high volume, acidic, or particulate aspiration. We further suggest not to delay surgery in healthy adults after confirming the removal of chewing gum. Make it a reward and less of a an addiction. An odds ratio procedure based on the Mantel-Haenszel method for combining study results using 2 x 2 tables was used with outcome frequency data. Excluded studies with reasoning are shown in the Supplemental Digital Content (https://links.lww.com/ALN/C933). Please refer to the table below. 6. Multiple versus single pharmacologic agents. Anesthesiology 2017; 126:376393 doi: https://doi.org/10.1097/ALN.0000000000001452. 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. A comparison of the volume and pH of gastric contents of obese and lean surgical patients. Do not routinely administer preoperative medications that block gastric acid secretion for the purpose of reducing the risk of pulmonary aspiration in patients with no apparent increased risk for pulmonary aspiration. The effects of chewing gum on gastric content prior to induction of general anesthesia. A light meal or nonhuman milk may be ingested for up to 6 h before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia..

Complications associated with anaesthesiaa prospective survey in France. The lack of sufficient scientific evidence in the literature may occur when the evidence is either unavailable (i.e., no pertinent studies found) or inadequate. Advise patients at every office visit to avoid exposure to environmental tobacco smoke at home, work, and in public places. Gastric volume and pH in infants fed clear liquids and breast milk prior to surgery. Copyright 2023, the American Society of Anesthesiologists. Single trials reported less hunger73 and greater satisfaction80 among patients drinking protein-containing clear liquids compared with patients drinking other clear liquids (very low strength of evidence). The literature is insufficient to evaluate the effect of preoperative antiemetics on the perioperative incidence of pulmonary aspiration, gastric volume, or pH.. GRADE guidelines: 2. Effect of preoperative oral carbohydrate administration on patients undergoing cesarean section with epidural anesthesia: A pilot study. Inconsistent results were reported for residual gastric volume. These guidelines do not address the use of antiemetics during the extended postoperative period after upper airway protective reflexes are no longer impaired. The carbohydrates may be simple or complex. That's a GOOD thing. The body of evidence included 10 studies (7 randomized controlled trials,9297,187 1 crossover study,98 1 single-arm study,188 and 1 case series189) comparing chewing gum (sugar-free or sugared) with fasting, water, or lollipops.

Practice guidelines for preoperative fasting and the use of pharmacologic agents to reduce the risk of pulmonary aspiration: Application to healthy patients undergoing elective procedures. 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. Both simple and complex carbohydratecontaining clear liquids were slightly more advantageous compared with noncaloric clear liquids in patient satisfaction. Braz J Anesthesiol (English Edition). Comparative trial of the effect of ranitidine and cimetidine on gastric secretion in fasting patients at induction of anaesthesia. Aspiration,49,53,55,57,80 regurgitation,55,68 and preoperative vomiting85 were not reported in any studies comparing protein-containing clear liquids with noncaloric clear liquids. Preoperative carbohydrate nutrition reduces postoperative nausea and vomiting compared to preoperative fasting. Antiemetics may be preoperatively administered to patients at increased risk of postoperative nausea and vomiting. 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. There is no clinically relevant increase in residual gastric volume after chewing gum92,9497 (low strength of evidence, supplemental fig. Influence of cigarette smoking on the risk of acid pulmonary aspiration. For these updated guidelines, systematically-reviewed studies used in the development of the previous update were combined with a systematic review of studies published subsequent to ASA approval in 2010. Preoperative oral feeding reduces stress response after laparoscopic cholecystectomy. Since nonhuman milk is similar to solids in gastric emptying time, consider the amount ingested when determining an appropriate fasting period. 1 Smokeless Tobacco and Oral Disease Smokeless tobacco can cause white or gray patches inside the mouth (leukoplakia) that can lead to cancer.
