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). Assuming a 1.1/10000 baseline incidence of aspiration to detect a 2-fold increase would require 214000 participants per arm in a two-arm study (power, 80%; , 0.05).

Trial participants ingested a median of 400ml of carbohydrate-containing clear liquids (interquartile range, 300 to 400ml) up to 2h before anesthesia administration. Carbohydrate-containing liquids may have an impact on blood glucose levels in patients with diabetes, especially patients who skip or reduce their usual hypoglycemics before surgery. Outcomes assessed were limited to gastric volume, gastric acidity, nausea, and vomiting (table 2). Nicotine is absorbed through the tissues of the mouth and in some cases swallowed. Throughout these guidelines, the term preoperative should be considered synonymous with preprocedural, as the latter term is often used to describe procedures that are not considered to be operations. colonel frank o'sullivan interview; beverly hills high school football 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. In addition, both the consultants and ASA members strongly agree that verification of their compliance with the fasting requirements should be assessed at the time of the procedure. 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. Procedures in which upper airway protective reflexes may be impaired. 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.

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. Supplemental tables 13 and 14 (https://links.lww.com/ALN/C934) detail the strength-of-evidence ratings. There was inconclusive evidence concerning residual gastric volume in nonsurgical studies that included comparisons of protein-containing clear liquids compared with carbohydrate-containing clear liquids alone (supplemental tables 11 and 12, https://links.lww.com/ALN/C934).
