The evidence comparing fasting with protein-containing clear liquids in adults was limited to single trials for each patient-reported outcome (table 4). 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. Free dissociable IGF-I: Association with changes in igfbp-3 proteolysis and insulin sensitivity after surgery. The guidelines do not apply to patients who undergo procedures with no anesthesia or only local anesthesia when upper airway protective reflexes are not impaired and when no risk factors for pulmonary aspiration are apparent. A randomized trial of preoperative oral carbohydrates in abdominal surgery. Southern African Journal of Anaesthesia and Analgesia 2020; 26(2)(Supplement 1):S1-75 SVI Foreword to the 2020-2025 edition of the SASA Guidelines for the safe use of procedural sedation and analgesia for diagnostic and therapeutic procedures in adults Writing guidelines on procedural sedation and analgesia is a formidable and challenging task. Randomized clinical trial comparing an oral carbohydrate beverage with placebo before laparoscopic cholecystectomy. 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 aim at reducing the risk for gastric content aspiration to the lowest possible, to avoid associated morbidity, unplanned hospital and/or an intensive care admission. 1 For patients undergoing elective procedures, this update addresses: Although controlled studies do not sufficiently evaluate such relationships, the reported evidence does focus on intermediate outcomes, including gastric contents (e.g., volume or pH) and nausea and vomiting, typically considered by the authors to be representative of a predicted risk of pulmonary aspiration. Antiemetics may be preoperatively administered to patients at increased risk of postoperative nausea and vomiting. Chewing gum was allowed either until induction or 30min to 1h before surgery. 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). The consultants and ASA members strongly agree that a review of pertinent medical records, a physical examination, and patient survey or interview should be performed as part of the preoperative evaluation.

Cochrane Bias Methods Group, Cochrane Statistical Methods Group. Category C: Informal Opinion. Supplemental digital content is available for this article. 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. Preoperative drinking does not affect gastric contents. 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. * The interventions listed in the evidence model below were examined to assess their impact on outcomes related to perioperative pulmonary aspiration. Effects of fasting and oral premedication on the pH and volume of gastric aspirate in children.

The mean age of participants was 43.2 yr, and 64% were female. The survey rate of return is 59.7% (n = 37 of 62) for the consultants (table 3), and 471 responses were received from active ASA members (table 4). In summary, the evidence showed that for patients with low risk of aspiration, carbohydrate-containing clear liquids until 2h preoperatively was superior to absolute fasting with respect to beneficial outcomes, without evidence of increased risks. Does preoperative oral carbohydrate treatment reduce the postoperative surgical stress response in lumbar disc surgery? Gastric emptying of preoperative carbohydrate in elderly assessed using gastric ultrasonography: A randomized controlled study. I can't imagine chewing tobacco particles in the lungs would go over well. Differences were not detected in rates of nausea36,39,4345 (low strength of evidence) or patient-rated nausea (low strength of evidence). Table 7 summarizes the evidence for clinically important outcomes. Effect of routine preoperative fasting on residual gastric volume and acid in patients undergoing myomectomy.

There was no incidence of aspiration in any group. 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.

Evaluating ranitidine, pantoprazole and placebo on gastric pH in elective surgery. Ingestion of liquids compared with preoperative fasting in pediatric outpatients. Use of ultrasound for gastric volume evaluation after ingestion of different volumes of isotonic solution. 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. 21, https://links.lww.com/ALN/C935, and supplemental table 15, https://links.lww.com/ALN/C934). The ASA members disagree and the consultants strongly disagree that preoperative multiple agents should be routinely administered before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia in patients with no apparent risk for pulmonary aspiration. 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). Insufficient Literature. Application to Healthy Patients Undergoing Elective Procedures: An Updated Report by the American Society of Anesthesiologists Committee on . Please refer to the table below.

The literature is insufficient to evaluate the effect of timing of the ingestion of breast milk and the perioperative incidence of pulmonary aspiration, gastric volume, pH, or emesis/reflux. Supplemental tables 1 to 4 (https://links.lww.com/ALN/C934) detail the strength-of-evidence ratings. The effect of metoclopramide on gastric contents after preoperative ingestion of sodium citrate. No studies reported industry funding, and 1 (11%) study reported a conflict of interest. Clear liquids may be ingested for up to 2 h before procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia. 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). Eligible studies included randomized and nonrandomized trials, quasiexperimental, cohort (prospective and retrospective), and case-control designs. Therefore, there is insufficient evidence to recommend protein-containing over other carbohydrate-containing or noncaloric clear liquids. Simple or complex carbohydratecontaining clear liquids appear to reduce hunger compared with noncaloric clear liquids. Smokeless tobacco products consist of tobacco that's chewed, sucked or sniffed, rather than smoked. All protein-containing clear liquids also contained carbohydrates.
