Abstract：
UNASSIGNED: Despite standard preoperative fasting guidelines, children are subjected to prolonged fasting due to various reasons. This does not reduce gastric residual volume (GRV) further, instead causes hypoglycemia, hypovolemia, and unnecessary discomfort. We calculated the cross-sectional area (CSA) of antrum and GRV in children in fasting state and 2 h after intake of oral carbohydrate-rich fluid, using gastric ultrasound.
UNASSIGNED: Anteroposterior and craniocaudal gastric antral diameters were measured by ultrasonography in the right lateral decubitus position, at fasting and at 2 h after 8 ml/kg of pulp-free fruit juice ingestion. CSA of antrum and GRV was calculated using validated mathematical models.
UNASSIGNED: Data of 149 children of age >1-12 years were analyzed. Greater than ninety-nine percent of children emptied ≥95% of the ingested pulp-free fruit juice volume within 2 h. One hundred and seven (71.8%) children had reduced CSA and GRV at 2 h after fruit juice ingestion (2.01 ± 1.00 cm2 and 7.77 ± 6.81 ml) as compared to fasting state (3.18 ± 1.40 cm2 and 11.89 ± 7.80 ml). Fourty-nine (28.2%) children had slightly increased CSA and GRV at 2 h after fruit juice (2.46 ± 1.14 cm2 and 10.61 ± 7.26 ml) than at fasting (1.89 ± 0.92 cm2 and 8.61 ± 6.75 ml), but this increased GRV was grossly lower than limit of risk stomach (26.54 ± 8.95 ml).
UNASSIGNED: Carbohydrate-rich drink in the form of pulp-free fruit juice may be safely permitted up to 2 h before anesthetic induction, as it promoted gastric emptying in ≈ 72% of children and 28% of children, although GRV was slightly higher at 2 h after fruit juice ingestion than fasting but remained considerably lower than limit of risk stomach.

摘要：
■尽管有标准的术前禁食指南，由于各种原因，儿童长期禁食。这不会进一步减少胃残留量（GRV），反而导致低血糖，血容量不足,和不必要的不适。我们计算了空腹状态下和摄入口服富含碳水化合物的液体后2小时儿童的胃窦横截面积（CSA）和GRV，用胃部超声检查.
■在右侧卧位通过超声检查测量前后和头尾胃窦直径，在禁食和摄入8ml/kg无浆果汁后2小时。使用经过验证的数学模型计算胃窦和GRV的CSA。
■分析了149名年龄>1-12岁儿童的数据。超过百分之九十九的儿童在2小时内排空了≥95％的摄入无浆果汁量。与禁食状态（3.18±1.40cm2和11.89±7.80ml）相比，摄入果汁后2h，有一百零七名（71.8％）儿童的CSA和GRV降低（2.01±1.00cm2和7.77±6.81ml）。果汁后2h（2.46±1.14cm2和10.61±7.26ml）的儿童CSA和GRV比禁食时（1.89±0.92cm2和8.61±6.75ml）略有增加（28.2％），但这种增加的GRV明显低于胃部风险极限(26.54±8.95ml)。
■无浆果汁形式的富含碳水化合物的饮料可以在麻醉诱导前2小时内安全允许，因为它促进了约72%的儿童和28%的儿童的胃排空，尽管摄入果汁后2小时的GRV略高于禁食，但仍远低于胃部风险极限。
