Abstract：
Pulmonary aspiration of gastric content is a serious perioperative complication. The objective of this prospective study was to assess the relationship between the gastric volumes suctioned endoscopically and quantitative (antral cross-section area) and qualitative (empty vs. nonempty) examination of the gastric antrum. Furthermore, the study aimed to determine the best antral cross-section area cutoff value for a truly empty antrum in infants.
This study was performed in a pediatric gastrointestinal endoscopy unit. Antral sonography was performed in supine and right lateral decubitus positions in 46 fasted infants prior to upper gastrointestinal endoscopic evaluation. Antral cross-sectional area measurements in both positions and qualitative evaluation of the antrum (according to a three-point grading system) were recorded. Gastric contents were endoscopically suctioned and measured.
Forty-six patients (aged under 24 months) were included. According to the three-point qualitative grading system, 76.1% of patients were classified as grade 0. The best cutoff value for the antral cross-section area in the right lateral decubitus position, indicating an empty antrum, was determined to be 2.40 cm2. At this specific cutoff value, the sensitivity was 100%, the specificity was 68.6%, and the negative predictive value was 100%.
Gastric ultrasonography can confirm an empty or nearly empty stomach in healthy infants.

摘要：
目的：胃内容物肺吸入是一种严重的围手术期并发症。这项前瞻性研究的目的是评估内窥镜抽吸的胃体积与定量（窦横截面面积）和定性（空与非空）胃窦检查。此外，该研究旨在确定婴儿真正空胃窦的最佳胃窦横截面面积截止值.
方法：本研究在儿科胃肠镜检查单元进行。在上消化道内镜评估之前，对46名禁食婴儿的仰卧位和右侧卧位进行了窦超声检查。记录两个位置的窦横截面积测量值和窦的定性评估（根据三点分级系统）。对胃内容物进行内镜抽吸和测量。
结果：纳入46例患者（24个月以下）。根据三点定性分级制度，76.1%的患者被分类为0级。右侧卧位窦横截面积的最佳截止值,表示一个空的胃窦，被确定为2.40cm2。在这个特定的截止值，灵敏度是100%,特异性为68.6%，阴性预测值为100%。
结论：胃超声检查可确认健康婴儿为空腹或接近空腹。
