Histamine-2 receptor antagonists: Meta-analysis of blinded placebo-controlled RCTs indicate that orally-administered ranitidine is effective in reducing gastric volume and acidity; the frequency of gastric volume > 25mL; the frequency of gastric pH levels < 2.5; and the risk of aspiration (i.e., gastric volume > 25mL and pH < 2.5) during the perioperative period (Category A1-B evidence).56,6170 Placebo-controlled RCTs of intravenous ranitidine report similar results for gastric pH (Category A2-B evidence) and equivocal findings for gastric volume (Category A2-E evidence).66,7174, Meta-analysis of placebo-controlled RCTs indicate that orally-administered cimetidine is effective in reducing gastric volume and acidity; the frequency of gastric volume > 25mL; the frequency of gastric pH levels < 2.5; and the risk of aspiration (i.e., gastric volume > 25mL and pH < 2.5) during the perioperative period (Category A1-B evidence).58,59,66,7587 Placebo-controlled RCTs of intravenous cimetidine report similar results for gastric pH (Category A2-B evidence), but equivocal findings for gastric volume (Category A2-E evidence).60,66,71,78,88. Results for each pertinent outcome are summarized and, when sufficient numbers of RCTs are found, formal meta-analyses are conducted. When warranted, the Task Force may add educational information or cautionary notes based on this information. Both the consultants and ASA members strongly agree that fasting from the intake of a meal that includes fried or fatty foods for 8 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained.

The mean age of participants was 47 yr, 70% were female, and the average body mass index was 23.9kg/m2. 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. Practice guidelines are subject to revision as warranted by the evolution of medical knowledge, technology, and practice. There is insufficient evidence to recommend protein-containing clear liquids preferentially over other clear liquids 2h before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation (no recommendation). In this document, only the highest level of evidence is included in the summary report for each intervention-outcome pair, including a directional designation of benefit, harm, or equivocality.

Investigation of preoperative fasting times in children. Tests for heterogeneity of the independent studies were conducted to assure consistency among the study results. Level 2: The literature contains multiple RCTs, but the number of RCTs is not sufficient to conduct a viable meta-analysis for the purpose of these updated guidelines. Observational studies indicate that some predisposing patient conditions (e.g., age, sex, ASA physical status, emergency surgery) may be associated with the risk of perioperative aspiration (Category B2-H evidence).15 Observational studies addressing other predisposing conditions (e.g., obesity, diabetes, esophageal reflux, smoking history) report inconsistent findings regarding risk of aspiration (Category B1-E evidence).611.

These guidelines are intended for use by anesthesiologists and other anesthesia providers. 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. Clear liquids may be ingested for up to 2 h before procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia. Anesthesiology 2017; 126:376393 doi: https://doi.org/10.1097/ALN.0000000000001452. The consultants agree and the ASA members strongly agree that for children, 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. 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 impact and safety of preoperative oral or intravenous carbohydrate administration. Perioperative glycemic measures among non-fasting gynecologic oncology patients receiving carbohydrate loading in an enhanced recovery after surgery (ERAS) protocol. The risk of bias for individual studies was evaluated using tools according to study design: for randomized controlled trials, the Cochrane risk of bias tool,16 and for nonrandomized studies, the Risk Of Bias In Non-Randomised Studies of Interventions tool.17 The risk of bias appraisals for only randomized controlled trials were used to support all strength-of-evidence ratings (supplemental figs. Assuming a 1.1/10000 baseline incidence of aspiration to detect a 2-fold increase would require 214000 participants per arm in a two-arm study (power, 80%; , 0.05). 1 For patients undergoing elective procedures, this update addresses: Post author: Post published: 24, 2023; Post category: is shane harper related to adam sandler; Post comments: .

Differences were not detected in vomiting99,100 or gastric pH99 between children fasted 1h versus 2h (low and very low strength of evidence, respectively). Important consideration should be given to comorbidities that may affect gastric emptying and/or aspiration risk, regardless of ASA Physical Status. The 2017 guideline also did not address chewing gum or whether a shorter duration of fasting from clear liquids would be more beneficial than the current recommendation of 2h of fasting for pediatric patients. The use of gastrozepin as a prophylaxis against pulmonary acid aspiration: a new muscarinic receptor antagonist. Airway management techniques that are intended to reduce the occurrence of pulmonary aspiration are not the focus of these guidelines. Gastric residual volume by magnetic ressonance after intake of maltodextrin and glutamine: A randomized double-blind, crossover study. The guidelines specifically focus on preoperative fasting recommendations, as well as recommendations regarding the administration of pharmacologic agents to modify the volume and acidity of gastric contents during procedures in which upper airway protective reflexes may be impaired.

Effect of oral and intramuscular famotidine on pH and volume of gastric contents. These evidence categories are further divided into evidence levels. 1 Clear liquids include water, tea, black coffee, pulp-free juice, and carbohydrate-rich drinks. Black or white coffee before anaesthesia? 1,3 Reproductive and Developmental Risks 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. Since nonhuman milk is similar to solids in gastric emptying time, consider the amount ingested when determining an appropriate fasting period. Ultrasound assessment of gastric volume in children after drinking carbohydrate-containing fluids. The complex carbohydrate used in the carbohydrate-loading interventions was maltodextrin. Only 2 of the trials randomized participants into 1- and 2-h fasting protocols; the remaining studies were not designed to compare 1- and 2-h fasting; however, they included results from pediatric patients fasted less than 2h. Most children were ASA Physical Status I or II, although one trial enrolling patients with cyanotic congenital heart disease were more likely of higher ASA Physical Status (ASA Physical Status not reported). Carbohydrate-containing liquids may have an impact on blood glucose levels in patients with diabetes, especially patients who skip or reduce their usual hypoglycemics before surgery. The methodologists also reviewed the strength of the evidence for each outcome by key question with the task force. An updated report by the ASA task force on preoperative fasting and use of pharmacologic agents to reduce the risk of pulmonary aspiration, which was adopted by the ASA in 2016 and published in 2017.1 The 2017 guideline did not address whether one type of clear liquid, such as water or carbohydrate-containing clear liquids (with and without protein), is more beneficial.

Shortened preanesthetic fasting interval in pediatric cardiac surgical patients. For adults undergoing elective procedures with general anesthesia, regional anesthesia, or procedural sedation, what are the benefits and harms of protein-containing clear liquids 2h before the procedure compared with fasting and other clear liquids? They provide basic recommendations that are supported by a synthesis and analysis of the current literature, expert and practitioner opinion, open forum commentary, and clinical feasibility data.

Metabolic profiles in children during fasting. Pre-operative ranitidine. Insulin sensitivity and beta-cell function after carbohydrate oral loading in hip replacement surgery: A double-blind, randomised controlled clinical trial. 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. Outcomes: adverse effects of fasting (preoperative hunger, thirst, and nausea) and pulmonary aspiration. Drinking carbohydrate-containing clear liquids resulted in lower hunger ratings than did noncaloric clear liquids (moderate strength of evidence).23,24,26,39,41,7275 Differences were not evident for patient ratings of thirst23,24,26,39,41,72,73,7577 (low strength of evidence) and nausea23,24,26,73 (low strength of evidence) or in rates of preoperative thirst78 and nausea23,24,26,39,73,79 (both very low strength of evidence).
