They provide basic recommendations that are supported by a synthesis and analysis of the current literature, expert and practitioner opinion, open forum commentary, and clinical feasibility data. The original guidelines and the previous update in 2011 was developed by means of a seven-step process. The lack of sufficient scientific evidence in the literature may occur when the evidence is either unavailable (i.e., no pertinent studies found) or inadequate. Influence of cigarette smoking on the risk of acid pulmonary aspiration. 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). 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. Preoperative drinking does not affect gastric contents. The effect of a new preoperative fasting regime on the subjective perception, postoperative recovery, postoperative complications, and satisfaction in pediatric patients.

Gastric emptying of three liquid oral preoperative metabolic preconditioning regimens measured by magnetic resonance imaging in healthy adult volunteers: A randomised double-blind, crossover study. Category A. RCTs report comparative findings between clinical interventions for specified outcomes. In addition, practice guidelines developed by the American Society of Anesthesiologists (ASA) are not intended as standards or absolute requirements, and their use cannot guarantee any specific outcome. Consider both the amount and type of foods ingested when determining an appropriate fasting period. 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. asa npo guidelines 2020 chewing tobaccohershey high school homecoming 2019.

A single randomized controlled trial reported higher satisfaction in parents of children with a 1-h clear liquid fast compared with parents of children with a 2-h clear liquid fast99 (very low strength of evidence). Links to the digital files are provided in the HTML text of this article on the Journals Web site (www.anesthesiology.org.). The consultants and ASA members both disagree that preoperative antiemetics should be routinely administered before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia in patients with no apparent increased risk for pulmonary aspiration. Single trials reported less hunger73 and greater satisfaction80 among patients drinking protein-containing clear liquids compared with patients drinking other clear liquids (very low strength of evidence).

The body of evidence was first described according to study characteristics and treatment arms. The authors declare no competing interests. Almost all adult study participants had an ASA Physical Status I or II (92%). Finally, there is a need for education of patients, their caregivers, and healthcare providers regarding avoidance of preoperative fasting beyond the recommended durations and the detrimental effects of prolonged fasting. Preoperative carbohydrate loading in patients undergoing thoracic surgery: A quality-improvement project. Airway management techniques that are intended to reduce the occurrence of pulmonary aspiration are not the focus of these guidelines.

The PRISMA flow diagram (https://links.lww.com/ALN/C931) and Literature Search Strategy (https://links.lww.com/ALN/C932) are available as Supplemental Digital Content. Nine (9%) trials included diabetic patients (from 2 to 100% of participants). Practice guidelines are systematically developed recommendations that assist the practitioner and patient in making decisions about health care. Clinical significance of pulmonary aspiration during the perioperative period. In the carbohydrate arms, liquids were allowed an average of 2.25h before surgery (80% until 2h). Tables 2 and 3 summarize the evidence for clinically important outcomes. The characteristics of randomized trials supporting recommendations for adult surgical patients included a median of 46 participants (range, 20 to 150). 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. The addition of protein to preoperative carbohydrate-containing clear liquids did not appear to either benefit or harm healthy patients. NPO Guidelines NPO Guidelines Guidelines for Adults and Teenagers Adults and teenagers over the age of 12 may have solid foods and dairy products until 8 hours before their scheduled arrival time at the hospital or surgery center.
