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. Level 1: The literature contains a sufficient number of RCTs to conduct meta-analysis, and meta-analytic findings from these aggregated studies are reported as evidence. Updated by the American Society of Anesthesiologists Task Force on Preoperative Fasting. Submitted for publication October 26, 2016. Safe pre-operative fasting times after milk or clear fluid in children. 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. Search terms consisted of the interventions indicated above guided by the appropriate inclusion/exclusion criteria as stated in the Focus section of these updated guidelines. Please refer to the table below. 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. Guidelines to the practice of anesthesia Revised edition 2022. For adults, clear liquids between 2 and 4 h versus more than 4 h, For children, clear liquids between 2 and 4 h versus more than 4 h, Breast milk between 2 and 4 h versus more than 4 h, Formula between 2 and 4 h versus more than 4 h, Solids less than 4 h versus more than 4 h, Solids between 4 and 8 h versus more than 8 h. Preoperative pharmacologic interventions: Other H2 receptor antagonists (e.g., roxatidin, nazatidine, gastrozepin), Other proton pump inhibitors (e.g., pantoprazole, rabeprazole). 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. The body of evidence included 9 studies (5 randomized controlled trials,99,100,102,104,106 1 crossover study,35 and 3 prospective cohort studies101,103,105) providing data on 1- and 2-h fasting in pediatric patients. The term gastroesophageal reflux disease refers to positional reflux and its consequent symptomology, rather than food intolerances (e.g., tomatoes do not agree with me). Smokeless tobacco products - Mayo Clinic Practice Guidelines for Preoperative Fasting and the Use of For pediatric patients undergoing elective procedures with general anesthesia, regional anesthesia, or procedural sedation, what are the benefits and harms of 1-h versus 2-h clear liquid fasting? 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.

Gastric fluid volume and pH in elective inpatients. The purpose of this modular update is to evaluate the current evidence on preoperative fasting, focusing on these interventions. Fifth, the Task Force held an open forum at a major national meeting to solicit input on its draft recommendations. Studies with multicomponent interventions (for example, enhanced recovery after surgery protocols) were excluded if the effect of fasting on outcomes could not be independently ascertained. Evidence categories refer specifically to the strength and quality of the research design of the studies. An acceptable significance level was set at P< 0.01 (one-tailed). The anesthesiologist and patient representative task force members rated the importance of each outcome for decision-making on a scale of 1 to 9 (1 to 3, of limited importance; 4 to 6, important; 7 to 9, critical).8 The evidence synthesis focused on the outcomes rated important or critical. Pre-operative oral carbohydrate treatment before coronary artery bypass surgery. In this framework, randomized control trials start as high strength of evidence, and nonrandomized studies start as low. 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). 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.

Effect of oral glucose water administration 1 hour preoperatively in children with cyanotic congenital heart disease: A randomized controlled trial. Both the consultants and ASA members strongly agree that for otherwise healthy infants (< 2 yr of age), children (2 to 16 yr of age) and adults, fasting from the intake of clear liquids for 2 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained. Level 3: The literature contains noncomparative observational studies with descriptive statistics (e.g., frequencies, percentages). The literature relating to seven evidence linkages contained enough studies with well-defined experimental designs and statistical information to conduct formal meta-analyses.
