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). Fasting Guidelines. Six additional studies provided data on gastric volume over time.35,102-106 Three of the studies102104 were consistent with a return to baseline gastric volume close to 2h, while three studies35,105,106 were consistent with a return at 1h (very low strength of evidence; supplemental table 20, https://links.lww.com/ALN/C934). Both the consultants and ASA members disagree that gastrointestinal stimulants 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.

The literature is insufficient to evaluate the effect of timing of the ingestion of infant formula on the perioperative incidence of pulmonary aspiration, gastric volume, pH or emesis/reflux. The routine administration of preoperative multiple agents is not recommended for patients with no apparent increased risk for pulmonary aspiration. Aspiration of gastric contents was not evident in the studies. The ASA members disagree and the consultants strongly disagree that preoperative multiple agents should be routinely administered before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia in patients with no apparent risk for pulmonary aspiration. chewing tobacco npo guidelines. 5. 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. Patients drinking carbohydrate-containing clear liquids until 2h before their procedures experienced less hunger and thirst compared to fasting (table 2) and less hunger compared to drinking noncaloric clear liquids (table 3). The intended population for this update is the same as for the 2017 ASA guideline, limited to healthy patients undergoing elective procedures.1 Healthy patients are those without coexisting diseases or conditions that may increase the risk for aspiration, including esophageal disorders such as significant uncontrolled reflux disease, hiatal hernia, Zenkers diverticulum, achalasia, stricture; previous gastric surgery (for example, gastric bypass); gastroparesis; diabetes mellitus; opioid use; gastrointestinal obstruction or acute intraabdominal processes; pregnancy; obesity; and emergency procedures.24 Anesthesiologists should recognize that these conditions can increase the likelihood of regurgitation and pulmonary aspiration and should modify these guidelines based upon clinical judgment. Preoperative carbohydrate loading in gynecological patients undergoing combined spinal and epidural anesthesia. Only studies containing original findings from peer-reviewed journals were acceptable. Trials provided participants with a median of 400ml (interquartile range, 300 to 400ml) of clear liquids 2h before anesthesia administration without adverse consequences.

Lansoprazole in the prophylaxis of acid aspiration during elective surgery. Comparisons and questions of interest include, Carbohydrate-containing clear liquids (simple and complex) compared with fasting and noncaloric clear liquids, Simple carbohydratecontaining clear liquids compared with complex carbohydratecontaining clear liquids, Carbohydrate-containing clear liquids (simple and complex) compared with clear protein-containing liquids alone, Protein-containing clear liquids alone compared with fasting and other clear liquids, Adding milk or cream to coffee or tea versus fasting and other clear liquids, The impact of carbohydrate-containing clear liquids on glycemic levels in patients with diabetes, There is a need for studies evaluating gastric volume, gastric emptying, and aspiration in patients with high risk of regurgitation.

Lansoprazole reduces preoperative gastric fluid acidity and volume in children. 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.
