Meta-analyses from other sources are reviewed but not included as evidence in this document. When these fasting guidelines are not followed, compare the risks and benefits of proceeding, with consideration given to the amount and type of liquids or solids ingested. All other recommendations from the 2017 guideline still apply. Fasting and Pharmacologic Recommendations. Although aspiration is uncommon in healthy ASA Physical Status I or II patients (estimated 1.1/10,000 adults and 1.3/10,000 children),24 it may lead to pneumonitis, pneumonia, and airway obstruction.5,6 Of the aspiration events described in the 2021 ASA Closed Claims analysis of aspiration of gastric contents events, 57% of aspiration incidents resulted in death, and another 15% resulted in permanent severe injury.4 The rationale for preoperative fasting is to minimize gastric content, thereby lowering the risk of regurgitation and subsequent pulmonary aspiration. Trial comparator liquids such as water, placebo, broth, black tea, and black coffee are referred to as noncaloric clear liquids.. You will also find usable tools to guide your practice and help you integrate tobacco treatment into routine clinical care.

I'd call tobacco somewhere between a "clear" liquid and a light meal and say 4 hours. For adults undergoing elective procedures with general anesthesia, regional anesthesia, or procedural sedation, what are the benefits and harms of protein-containing clear liquids 2h before the procedure compared with fasting and other clear liquids? Results for each pertinent outcome are summarized and, when sufficient numbers of RCTs are found, formal meta-analyses are conducted. To avoid prolonged fasting in children, efforts should be made to allow clear liquids in children at low risk of aspiration as close to 2h before procedures as possible.

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? 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. 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. I'm now going for no booze or caffeine for Lent. Randomized clinical trial to compare the effects of preoperative oral carbohydrate.

According to the American Society of Anesthesiologists (ASA) Preoperative Fasting Guidelines for Healthy Patients of All Ages, it is recommended that all patients abstain from drinking clear liquids 2 hours prior to elective surgery. Evidence was obtained from two principal sources: scientific evidence and opinion-based evidence (appendix 2). Practice guidelines are systematically developed recommendations that assist the practitioner and patient in making decisions about health care. If I take food in through an enteral or nasogastric tube (e.g., gastric/stomach tube, enteral/jejunostomy tube, etc.) An RCT comparing a light breakfast consumed less than 4 h before a procedure with overnight fasting reports equivocal findings for gastric volume and pH levels for adults (Category A3-E evidence).47 A second RCT reports equivocal findings when a light breakfast is allowed at 4 h compared with 6 h before a cesarean section (Category A3-E evidence), although a significant reduction in maternal and neonatal blood glucose levels was reported when fasting was extended beyond 6 h (Category A3-H evidence).48 Nonrandomized comparative studies for children given nonhuman milk 4 h or less before a procedure versus children fasted for more than 4 h report equivocal findings for gastric volume and pH (Category B1-E evidence).4951 One nonrandomized study indicated that fasting for more than 8 h may be associated with significantly lower blood glucose levels (Category B1-H evidence).51 The literature is insufficient to evaluate the effect of the timing of ingestion of solids and nonhuman milk and the perioperative incidence of pulmonary aspiration or emesis/reflux.

The guidelines do not address the selection of anesthetic technique, nor do they address enhanced recovery protocols not designed to reduce the perioperative risk of pulmonary aspiration. The effect of preoperative oral carbohydrate solution intake on patient comfort: A randomized controlled study. The history, examination, and interview should include assessment of ASA physical status, age, sex, type of surgery, and potential for difficult airway management as well as consideration of gastroesophageal reflux disease,* dysphagia symptoms, other gastrointestinal motility and metabolic disorders (e.g., diabetes mellitus) that may increase the risk of regurgitation and pulmonary aspiration. Preoperative oral carbohydrate treatment attenuates immediate postoperative insulin resistance. 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).
