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). No differences in the occurrence of regurgitation were detected. Aspiration can occur during any type of anesthesia, as a result of . 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. Comparators of interest include, Carbohydrate- and protein-containing clear liquids alone and in combination.

These liquids should not include alcohol. Inadequate literature cannot be used to assess relationships among clinical interventions and outcomes because a clear interpretation of findings is not obtained due to methodological concerns (e.g., confounding of study design or implementation) or the study does not meet the criteria for content as defined in the Focus of the guidelines. 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. Antacids may be preoperatively administered to patients at increased risk of pulmonary aspiration. Decision-making is complicated by emerging data suggesting that some of the conditions traditionally considered to have an impact on gastric emptying may have little or no effect on gastric emptying.
