d trial. After receiving 3 mL kg–1 clear fluid, participants were randomized to have a gastric ultrasound after fasting for either 1 hour (1-hour group, n = 116) or 2 hours (2-hour group, n = 111). Our primary outcome was the GFV. Other outcomes included the antral cross-sectional area, frequency of high risk and low risk of aspiration, and qualitative grading for the gastric antrum. RESULTS: Two hundred and twenty-seven children were available for final analysis. The median (Q1–Q3) GFV was higher in the 1-hour group versus the 2-hour group (0.61 [0.41–0.9] mL kg–1 vs 0.32 [0.23–0.47] mL kg–1; P value = .001). None of the study groups had GFV ≥1.5 mL kg–1. The frequency (%) of GFV ≥1.25 mL kg–1 was comparable between both groups (2 [1.7%] vs 0 [0%], P value = .165). However, the frequency of GFV ≥0.8 mL kg–1 was higher in 1-hour group than in 2-hour group (34.5% vs 4.5%), and grade 2 antral grading score was 56.9% in 1-hour group vs 0.9% in 2-hour group (P value <.001). CONCLUSIONS: In healthy children scheduled for elective surgery receiving 3 mL kg–1 clear fluid, the median GFV after 1-hour fasting was double the volume after conventional 2-hour fasting. These findings should be considered whether weighting the risk/benefit of a liberal approach to preoperative fasting versus the risk of pulmonary aspiration....

清流质禁食 1 小时与 2 小时后计划接受择期手术的儿童胃液量的超声评估:一项随机对照试验

d 审判。在接受 3 mL kg-1 透明液体后,参与者被随机分配到禁食 1 小时(1 小时组,n = 116)或 2 小时(2 小时组,n = 111)后进行胃超声检查。我们的主要成果是 GFV。其他结果包括胃窦横截面积、高风险和低风险误吸的频率以及胃窦的定性分级。结果:227 名儿童可用于最终分析。1 小时组的中位 (Q1–Q3) GFV 高于 2 小时组(0.61 [0.41–0.9] mL kg–1 对比 0.32 [0.23–0.47] mL kg–1;P 值 = .001 ). 没有一个研究组的 GFV ≥ 1.5 mL kg–1。GFV ≥ 1.25 mL kg-1 的频率 (%) 在两组之间具有可比性(2 [1.7%] 对比 0 [0%],P 值 = .165)。然而,GFV的频率≥0。1 小时组 8 mL kg–1 高于 2 小时组(34.5% vs 4.5%),1 小时组 2 级胃窦分级评分为 56.9% vs 2 小时组 0.9%(P值 <.001)。结论:在接受 3 mL kg-1 透明液体的择期手术健康儿童中,禁食 1 小时后的中位 GFV 体积是常规禁食 2 小时后的两倍。应考虑这些发现是否权衡了术前禁食的宽松方法的风险/益处与肺部误吸的风险……
