I find that the ASA NPO guidelines are usually not that specific when it comes to the patient who has forgotten to stay NPO (or is too stupid to do so) because this type of patient is diabetic, obese, with a hiatal hernia anyway, and so the guidelines don't say much except use your judgement. 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. When an equal number of categorically distinct responses are obtained, the median value is determined by calculating the arithmetic mean of the two middle values. 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. 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.

The outcomes of interest for this update include the adverse consequences of fasting (hunger, thirst, and preoperative nausea and vomiting) and pulmonary aspiration. 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.

Age limits It is illegal to sell or supply tobacco products to young people under the age of 18. Moreover, there is a need to study gastric emptying and gastric pH in critically ill patients receiving enteral feeding to determine the shortest safe duration of fasting before surgery in that population to minimize feeding interruptions. There is insufficient evidence concerning benefits and harms to recommend pediatric patients drink clear liquids until 1h versus 2h before procedures with general anesthesia, regional anesthesia, or procedural sedation (no recommendation).
