Preoperative fastingnihil per os a difficult myth to break down: A randomized controlled study. 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. Ultrasound assessment of gastric emptying time after intake of clear fluids in children scheduled for general anesthesia: A prospective observational study. No aspiration was reported after either the fasting or carbohydrate-containing clear liquids groups in 31 randomized controlled trials,2326,29,30,32,33,36,37,39,4244,4764 2 nonrandomized trials,65,66 and 1 case-control study67 (strength of evidence not rated due to lack of events). 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. The goal for preoperative fasting is to reduce the risk of aspiration of gastric contents. Potential inclusionexclusion discrepancies were also examined with an artificial intelligence tool, a component of the systematic review software. Approximately one half (53%) were conducted in low-resource countries (Human Development Index scores less than 0.8). Retrospective comparative studies (e.g., case-control). 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. Does preoperative oral carbohydrate treatment reduce the postoperative surgical stress response in lumbar disc surgery? Dr. Joshi is a consultant for Baxter Healthcare (Deerfield Illinois) and Pacira Pharmaceuticals (Parsippany New Jersey), Dr. Abdelmalak is a consultant and speaker for Acacia Pharma (Duxford United Kingdom) and Medtronic USA Inc. (Minneapolis Minnesota), and Dr. Domino has received a research grant from Edwards Life Science Corporation (Irvine California). No differences in the occurrence of regurgitation were detected. They also may serve as a resource for other health care professionals who advise or care for patients who receive anesthesia care during procedures. The evidence comparing fasting with protein-containing clear liquids in adults was limited to single trials for each patient-reported outcome (table 4). A carbohydrate-rich drink reduces preoperative discomfort in elective surgery patients. Both the systematic literature review and opinion data are based on evidence linkages, or statements regarding potential relationships between preoperative fasting interventions and pulmonary aspiration or associated complications. Large volumes of apple juice preoperatively do not affect gastric pH and volume in children. A carbohydrate-rich drink shortly before surgery affected IGF-I bioavailability after a total hip replacement. For adults undergoing elective procedures with general anesthesia, regional anesthesia, or procedural sedation, what are the benefits and harms of carbohydrate-containing clear liquids ingested until 2h before the procedure compared with fasting and noncaloric clear liquids? The consultants agree and the ASA members strongly agree that for children, fasting from the intake of infant formula for 6 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained. Fasting duration is often substantially longer than recommended irrespective of a 1- or 2-h clear liquid fasting policy.107112 Prolonged fasting influences patient-related outcomes (preoperative thirst, hunger, anxiety, nausea and vomiting, pain, and reduced feeling of well-being) and clinical outcomes (dehydration, electrolyte imbalance, and hypotension at induction of general anesthesia).113,114 Due to low-quality evidence, the task force was unable to make a recommendation for reducing the clear liquid fasting duration to 1h in the pediatric population. Any benefits of gum chewing are inconsistent and insufficiently studied to encourage gum chewing before surgery. An acceptable significance level was set at P< 0.01 (one-tailed). The American Society of Anesthesiologists (ASA) recommends patients to fast from fatty food or meats eight (8) hours prior to surgery, non-human milk or light meal for six (6) hours prior, breast milk for four (4) hours prior, and clear liquids including water, pulp-free juice, and tea or coffee without milk for two (2) hours prior to the Pre-operative carbohydrate loading prior to elective caesarean delivery: A randomised controlled trial. A randomized trial of preoperative oral carbohydrates in abdominal surgery. One study included younger children (mean age, 3 yr), 2 included children with mean or median age of 5 yr, and the remaining studies reported median ages ranging from 7 to 11 yr. Five studies were conducted in surgical settings, and 4 were nonsurgical. (Chair), Chicago, Illinois; Madhulika Agarkar, M.P.H., Schaumburg, Illinois; Richard T. Connis, Ph.D., Woodinville, Washington; Charles J. Cot, M.D., Boston, Massachusetts; David G. Nickinovich, Ph.D., Bellevue, Washington; and Mark A. Warner, M.D., Rochester, Minnesota. Both the consultants and ASA members strongly agree that fasting from the intake of a meal that includes fried or fatty foods for 8 or more hours before elective procedures requiring general anesthesia, regional anesthesia, or procedural sedation and analgesia should be maintained. * The interventions listed in the evidence model below were examined to assess their impact on outcomes related to perioperative pulmonary aspiration. First, the Task Force reached consensus on the criteria for evidence. Impact of enhanced recovery after surgery with preoperative whey protein-infused carbohydrate loading and postoperative early oral feeding among surgical gynecologic cancer patients: An open-labelled randomized controlled trial. These recommendations may be adopted, modified, or rejected according to clinical needs and constraints, and are not intended to replace local institutional policies. Actively encouraging clear liquids in healthy children as close to 2h before procedures as possible is important to avoid them. 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). For healthy adults undergoing elective procedures with general anesthesia, regional anesthesia, or procedural sedation, what are the effects of chewing gum on residual gastric volume, gastric pH, and pulmonary aspiration before anesthesia induction? Third, expert consultants were asked to: (1) participate in opinion surveys on the effectiveness of various preoperative fasting strategies and pharmacologic agents and (2) review and comment on a draft of the guidelines developed by the Task Force.

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). 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).

Use of ultrasound for gastric volume evaluation after ingestion of different volumes of isotonic solution. When tobacco is smoked, nicotine rapidly reaches peak levels in the bloodstream and enters the brain; if the smoke is not directly inhaled into the lungs, nicotine is absorbed . Excluding the single trial of gastric bypass patients, the average of either mean or median body mass index was 25.1kg/m2 (range, 21 to 33). Results for each pertinent outcome are summarized and, when sufficient numbers of RCTs are found, formal meta-analyses are conducted.
