They also may serve as a resource for other health care professionals who advise or care for patients who receive anesthesia care during procedures. Fasting duration is often substantially longer than recommended irrespective of a 1- or 2-h clear liquid fasting policy.107112 Prolonged fasting influences patient-related outcomes (preoperative thirst, hunger, anxiety, nausea and vomiting, pain, and reduced feeling of well-being) and clinical outcomes (dehydration, electrolyte imbalance, and hypotension at induction of general anesthesia).113,114 Due to low-quality evidence, the task force was unable to make a recommendation for reducing the clear liquid fasting duration to 1h in the pediatric population. Survey responses from expert and membership sources are recorded using a 5-point scale and summarized based on median values. Eligible studies included randomized and nonrandomized trials, quasiexperimental, cohort (prospective and retrospective), and case-control designs. These guidelines do not address the use of antiemetics during the extended postoperative period after upper airway protective reflexes are no longer impaired. 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. Examples of clear liquids include, but are not limited to, water, and fruit juices without pulp, carbonated beverages, carbohydrate-rich nutritional drinks, clear tea, and black coffee.

Most patients in the studies were ASA Physical Status I or II with mean or median body mass index of 25kg/m2 (range, 21 to 33kg/m2; see Appendix). Both the consultants and ASA members agree that for infants, 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. If you are not looking for the service manual, but need installation instructions, we have several different manuals and instructions so you can choose the right one. The consultants and ASA members both strongly agree that, when antacids are indicated for selected patients, only nonparticulate antacids should be used. Select options. Small study effects and the potential for publication bias were evaluated using funnel plots and regression-based tests.12 Analyses were conducted in R (R Foundation for Statistical Computing, Vienna, Austria).1315 (See the methods supplement for further details, https://links.lww.com/ALN/C962.). Clear fluids three hours before surgery do not affect the gastric fluid contents of children.

Oral use of chewing tobacco or snuff should be stopped a minimum duration of six hours before a procedure. The routine administration of preoperative multiple agents is not recommended for patients with no apparent increased risk for pulmonary aspiration. 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). Ties are calculated by a predetermined formula. 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). Four (22%) trials included diabetic patients (from 9 to 31% of participants). 1 Smokeless tobacco can cause gum disease, tooth decay, and tooth loss.

Several pediatric anesthesia practices in the United States now utilize the 1-h fasting duration for clear liquids. 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. 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. Single-dose oral omeprazole for reduction of gastric residual acidity in adults for outpatient surgery. All studied protein-containing clear liquids also contained carbohydrates. 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. Decision-making is complicated by emerging data suggesting that some of the conditions traditionally considered to have an impact on gastric emptying may have little or no effect on gastric emptying. Effects of a carbohydrate-, glutamine-, and antioxidant-enriched oral nutrition supplement on major surgery-induced insulin resistance: A randomized pilot study. The percent of consultants expecting no change associated with each linkage were as follows: preoperative assessment 95%; preoperative fasting of solids 75%; preoperative fasting of liquids 67%; preoperative fasting of breast milk 78%; gastrointestinal stimulants 95%; pharmacologic blockage of gastric secretion 91%; antacids 100%; antiemetics 98%, anticholinergics 100%, and multiple agents 98%.

To evaluate potential publishing bias, a fail-safe n value was calculated. Although differences were not detected in thirst, preoperative nausea, or patient satisfaction, the body of evidence is consistent with lower patient ratings of hunger with carbohydrate-containing clear liquids over noncaloric ones. 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.

Smokeless tobacco products consist of tobacco that's chewed, sucked or sniffed, rather than smoked. 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. Therefore, to avoid prolonged fasting in children, efforts should be made to allow clear liquids in healthy children as close to 2h before procedures as possible. asa npo guidelines 2020 chewing tobacco . A laboratory can only produce high quality results if the integrity of samples is maintained. Placebo-controlled RCTs indicate that orally-administered famotidine is effective in reducing gastric volume and acidity during the perioperative period (Category A2-B evidence).64,8991 One placebo-controlled RCT reports similar findings for intramuscular famotidine (Category A3-B evidence).92 The literature is insufficient to evaluate the effect of administering histamine-2 receptor antagonists on perioperative pulmonary aspiration or emesis/reflux.
