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. The characteristics of randomized trials supporting recommendations for adult surgical patients (aspiration was assessed across study designs, but the strength of evidence was unable to be rated) included a mean of 95 participants (range, 15 to 880). The body of evidence included 139 studies (adult surgical: 99 randomized controlled trials,2334,3664,6886,91,118157 7 nonrandomized trials,65,66,87,152,158160 3 prospective cohort studies,90,161,162 2 retrospective cohort studies,163,164 1 case-control study,165 and 2 beforeafter studies67,166; adult nonsurgical: 1 randomized controlled trial,167 9 crossover,168176 and 2 nonrandomized trials177,178; pediatric surgical: 9 randomized controlled trials,100,113,179185 1 prospective cohort186; and pediatric nonsurgical: 2 randomized controlled trial,102,104 1 crossover,35 and 1 prospective cohort103) comparing carbohydrate-containing clear liquids (simple, complex) with water, placebo, or fasting. chewing tobacco npo guidelines.

Both simple and complex carbohydratecontaining clear liquids were slightly more advantageous compared with noncaloric clear liquids in patient satisfaction. These guidelines do not address the use of antiemetics during the extended postoperative period after upper airway protective reflexes are no longer impaired.
