In addition, findings from both the Fisher and weighted Stouffer combined tests must agree with each other. Framing the question and deciding on important outcomes. A comparison of rabeprazole, lansoprazole, and ranitidine for improving preoperative gastric fluid property in adults undergoing elective surgery. Effects of preoperative carbohydrate loading on glucose metabolism and gastric contents in patients undergoing moderate surgery: a randomized, controlled trial. 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. Up to 400ml of clear liquids is considered an appropriate volume. 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 double-blind placebo controlled study on 29 patients. No studies reported industry funding, and 1 (11%) study reported a conflict of interest. A randomized trial. 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. Safety and feasibility of oral carbohydrate consumption before cesarean delivery on patients with gestational diabetes mellitus: A parallel, randomized controlled trial. Only studies containing original findings from peer-reviewed journals were acceptable. Mixed treatment comparisons did not support the superiority of complex carbohydrates over simple carbohydrates with respect to residual gastric volume or hunger (network meta-analysis; supplemental figs. 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. A randomized trial of preoperative oral carbohydrates in abdominal surgery. 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). Effects of oral preoperative carbohydrate on early postoperative outcome after thyroidectomy. This was my first step in dramatically reducing my alcohol intake. Pre-operative oral carbohydrate loading in colorectal surgery: A randomized controlled trial. Since nonhuman milk is similar to solids in gastric emptying time, consider the amount ingested when determining an appropriate fasting period. Residual gastric fluid volume and chewing gum before surgery. Lansoprazole reduces preoperative gastric fluid acidity and volume in children. Effects of famotidine on gastric pH and residual volume in pediatric surgery. The guideline topics were approved by the Guidelines Committee and the ESAIC Board after a consultation process within the subcommittees of the ESAIC Scientific Committee. 5. Chewing gum, sucking hard candy on the morning of surgery may stimulate . Eligible studies included randomized and nonrandomized trials, quasiexperimental, cohort (prospective and retrospective), and case-control designs. 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 An Updated Report by the American Society of Anesthesiologists Task Force on Preoperative Fasting and the Use of Pharmacologic The role of H2 receptor antagonist premedication in pregnant day care patients. The effect of pre-operative intake of oral water and ranitidine on gastric fluid volume and pH in children undergoing elective surgery. Cimetidine for prophylaxis of aspiration pneumonitis: comparison of intramuscular and oral dosage schedules. The American Society of Anesthesiologists (ASA) recommends patients to fast from fatty food or meats eight (8) hours prior to surgery, non-human milk or light meal for six (6) hours prior, breast milk for four (4) hours prior, and clear liquids including water, pulp-free juice, and tea or coffee without milk for two (2) hours prior to the netmeta: Network meta-analysis using frequentist methods. Scientific evidence used in the development of these updated guidelines is based on cumulative findings from literature published in peer-reviewed journals. Effects of preoperative oral carbohydrates on quality of recovery in laparoscopic cholecystectomy: A randomized, double blind, placebo-controlled trial. asa npo guidelines 2020 chewing tobacco asa npo guidelines 2020 chewing tobacco vo 9 Thng Su, 2022 vo 9 Thng Su, 2022 (Chair). Gastric fluid volume and pH in elective inpatients. chewing tobacco npo guidelines Statement on Surgical Attire (Amended October 26, 2022) Statement on the Aging Anesthesiologist. Do not routinely administer preoperative antacids for the purpose of reducing the risk of pulmonary aspiration in patients with no apparent increased risk for pulmonary aspiration. The impact of oral carbohydrate-rich supplement taken two hours before caesarean delivery on maternal and neonatal perioperative outcomesA randomized clinical trial. Clear liquids containing less than 10 gm/ml carbohydrate were not considered carbohydrate-containing. For the previous update, consensus was obtained from multiple sources, including: (1) survey opinion from consultants who were selected based on their knowledge or expertise in preoperative fasting and prevention of pulmonary aspiration, (2) survey opinions solicited from active members of the ASA membership, (3) testimony from attendees of a publicly-held open forum for the original guidelines held at a national anesthesia meeting, (4) Internet commentary, and (5) Task Force opinion and interpretation. Metabolic and inflammatory benefits of reducing preoperative fasting time in pediatric surgery. 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). One randomized controlled trial comparing 2 h fasting with fasting from midnight reported equivocal findings for blood glucose and insulin values (Category A3-E evidence).43. Please be advised that if you have any questions regarding NPO status, call or email our office prior to the day of surgery for an answer. Comfort, safety and quality of upper gastrointestinal endoscopy after 2 hours fasting: A randomized controlled trial. The characteristics of randomized trials supporting recommendations for adult surgical patients included a median of 46 participants (range, 20 to 150). A randomized controlled study of preoperative oral carbohydrate loading. Rectal and oral cimetidine for prophylaxis of aspiration pneumonitis in paediatric anaesthesia. Four (22%) trials included diabetic patients (from 9 to 31% of participants). The consultants agree and the ASA members strongly agree that for children and adults, fasting from the intake of nonhuman milk for 6 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained. Additional fasting time (e.g., 8 or more hours) may be needed in cases of patient intake of fried foods, fatty foods, or meat. Three (30%) studies enrolled patients rated with ASA Physical Status I or II, and 1 (10%) study included ASA Physical Status I to III (6 [60%] studies did not report ASA Physical Status).
