Patients chewing gum had a minimally increased residual gastric volume at anesthesia induction compared with fasting (table 6). Effects of preoperative fasting abbreviation with carbohydrate and protein solution on postoperative symptoms of gynecological surgeries: Double-blind randomized controlled clinical trial. Procedures in which upper airway protective reflexes may be impaired. A preliminary study using real-time ultrasound. 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. Level 1: The literature contains observational comparisons (e.g., cohort, case-control research designs) with comparative statistics between clinical interventions for a specified clinical outcome. Effects of preoperative oral carbohydrate administration on patient well-being and satisfaction in thyroid surgery. Case reports and case series, conference abstracts, letters not considered research reports, non-English publications, and animal studies were excluded. Due to the rarity of aspiration, regurgitation, gastric volume, and gastric pH were included as intermediate outcomes. Aspiration of gastric contents was not evident in the studies. Proton pump inhibitors: Meta-analysis of placebo-controlled RCTs indicate that omeprazole is effective in reducing gastric volume and acidity (Category A1-B evidence).63,67,9395 RCTs report similar findings for lansoprazole (Category A2-B evidence),67,68,96,97 pantoprazole (Category A2-B evidence),63,73,98 and rabeprazole (Category A3-B evidence).68 The literature is insufficient to evaluate the effect of administering proton pump inhibitors on perioperative pulmonary aspiration or emesis/reflux. Smokeless tobacco causes cancer of the mouth, esophagus, and pancreas. Clinical practice includes, but is not limited to, withholding of liquids and solids for specified time periods before surgery and prescribing pharmacologic agents to reduce gastric volume and acidity. Single-dose oral omeprazole for reduction of gastric residual acidity in adults for outpatient surgery. 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. Evidence was inconsistent for thirst,73,76 and differences in nausea85 were not observed. Insulin resistance after cardiopulmonary bypass in the elderly patient. A randomized controlled trial of preoperative carbohydrate drinks on postoperative walking capacity in elective colorectal surgery. Anesthesiology 2023; 138:132151 doi: https://doi.org/10.1097/ALN.0000000000004381. Assessment of age-related acid aspiration risk factors in pediatric, adult, and geriatric patients. Effects of 2-, 4- and 12-hour fasting intervals on preoperative gastric fluid pH and volume, and plasma glucose and lipid homeostasis in children. Outcomes: adverse effects of fasting (preoperative hunger, thirst, and nausea) and pulmonary aspiration. All protein-containing clear liquids also contained carbohydrates. 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). Both the consultants and ASA members disagree that histamine-2 receptor antagonists 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 body of evidence was first described according to study characteristics and treatment arms. 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? Since nonhuman milk is similar to solids in gastric emptying time, consider the amount ingested when determining an appropriate fasting period. Simple carbohydrates included clear fruit juices or water with glucose or fructose added. For these guidelines, preoperative fasting is defined as a prescribed period of time before a procedure when patients are not allowed the oral intake of liquids or solids. Insufficient Literature. The evidence in adults comparing noncaloric clear liquids with those containing protein was limited, with one to two studies reporting each outcome of interest (table 5). 1 Smokeless Tobacco and Oral Disease Smokeless tobacco can cause white or gray patches inside the mouth (leukoplakia) that can lead to cancer. Meta-analysis of RCTs comparing fasting times of 2 to 4 h versus more than 4 h report equivocal findings for gastric volume and gastric pH values in adult patients given clear liquids 2 to 4 h before a procedure (Category A1-E evidence).1221 RCTs reported less thirst and hunger for fasting times of 2 to 4 h versus more than 4 h (Category A2-B evidence).12,13,19,2224 Similarly, RCTs comparing nutritional or carbohydrate drinks at 2 to 4 h versus more than 4 h of fasting report equivocal findings for gastric volume, gastric pH, blood glucose values, hunger, and thirst (Category A2-E evidence).15,21,2432 A meta-analysis of RCTs reports a lower risk of aspiration (i.e., gastric volume < 25mL and pH > 2.5) when clear liquids are given 2 to 4 h before a procedure (Category A1-B evidence).12,13,16,17,19,20, Meta-analysis of RCTs report higher gastric pH values (Category A1-B evidence) and equivocal findings regarding differences in gastric volume (Category A1-E evidence) for children given clear liquids 2 to 4 h versus fasting for more than 4 h before a procedure.3342 Ingested volumes of clear liquids in the above studies range from 100ml to unrestricted amounts for adults, and 2ml/kg to unrestricted amounts for children. 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.

Preoperative pharmacologic interventions: Other H2 receptor antagonists (e.g., roxatidin, nazatidine, gastrozepin), Other proton pump inhibitors (e.g., pantoprazole, rabeprazole). The administration of preoperative anticholinergics to reduce the risk of pulmonary aspiration is not recommended. Population: patients undergoing general anesthesia, regional anesthesia, or procedural sedation for elective procedures, Interventions: drinking carbohydrate-containing clear liquids (simple or complex) until 2h before general anesthesia, regional anesthesia, or procedural sedation for elective procedures; drinking protein-containing clear liquids (all studied included carbohydrates) until 2h before general anesthesia, regional anesthesia, or procedural sedation for elective procedures; gum chewing before surgery/procedure; and a shortened duration for clear liquid fasting in children of 1 h, Comparators: fasting or drinking noncaloric clear liquids (e.g., water, placebo, broth, black tea, black coffee); no gum chewing; and clear liquid fasting duration of 2h in pediatric patients. For the first time, the 2020 data include information on the flavors of the companies' smokeless tobacco products. 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 administered due to the risk of pulmonary aspiration, a serious complication in which stomach contents are drawn into the respiratory tract during breathing. That's a GOOD thing. Welcome! A randomized trial of preoperative oral carbohydrates in abdominal surgery. chewing tobacco npo guidelines. A difference was not detected in gastric pH92,9497 (low strength of evidence, supplemental table 16, https://links.lww.com/ALN/C934). Oral rehydration with 10% carbohydrate drink for preventing postoperative nausea and vomiting (PONV) after low dose of spinal morphine.

Large volumes of apple juice preoperatively do not affect gastric pH and volume in children. The characteristics of randomized trials supporting recommendations for adult surgical patients (aspiration was assessed across study designs, but the strength of evidence was unable to be rated) included a mean of 95 participants (range, 15 to 880). Support was provided by the American Society of Anesthesiologists (Schaumburg, Illinois) and developed under the direction of the Committee on Practice Parameters, Karen B. Domino, M.D., M.P.H. Identification of patients at increased risk of pulmonary aspiration (e.g., obesity, diabetes, smoking history): Medical records review (focused history). Although the literature is insufficient to evaluate the influence of preoperatively adding milk or milk products to clear liquids (e.g., tea or coffee) on either pulmonary aspiration, gastric volume, pH, or gastric emptying, some studies with healthy volunteer subjects have reported equivocal findings for gastric volume and gastric emptying when these products are added to clear liquids.5254. 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. Evidence levels refer specifically to the strength and quality of the summarized study findings (i.e., statistical findings, type of data, and the number of studies reporting/replicating the findings). Gastric emptying of clear liquid drinks assessed with gastric ultrasonography: A blinded, randomized pilot study. The figures were digitized as necessary to obtain quantitative results for synthesis. Both the systematic literature review and opinion data are based on evidence linkages, or statements regarding potential relationships between preoperative fasting interventions and pulmonary aspiration or associated complications. Effect of gum chewing on the volume and pH of gastric contents: A prospective randomized study. 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. 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. Differences were not detected in vomiting99,100 or gastric pH99 between children fasted 1h versus 2h (low and very low strength of evidence, respectively). Volume and pH of gastric juice in obese 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.
