To investigate the clinical utility of the 3-ounce (90-cc) water swallow challenge alone to determine both aspiration status and oral feeding recommendations in children.
Cross-sectional evaluation of a diagnostic test with a consecutive, referral-based sample.
Urban, tertiary care, teaching hospital.
Fifty-six children (age range 2-18 years; mean 13 years) referred for swallowing evaluations.
Aspiration status during fiberoptic endoscopic evaluation of swallowing (FEES) was the objective criterion standard with which results from the 3-ounce water swallow challenge were compared.
Twenty-two (39.3%) participants passed and 34 (60.7%) failed the 3-ounce challenge. Sensitivity for predicting aspiration status during FEES = 100.0 percent, specificity = 51.2 percent, and false-positive rate = 48.4 percent. Sensitivity for identifying individuals who were deemed safe for oral intake based on FEES results = 100.0 percent, specificity = 44.0 percent, and false-positive rate = 56.0 percent.
If the 3-ounce water swallow challenge is passed, not only thin liquids but diet recommendations with puree and solid food consistencies can be made without the need for further instrumental dysphagia assessment.
The 3-ounce water swallow challenge has been shown to be a clinically useful screening test for oropharyngeal dysphagia in children.
探讨仅采用3盎司（90毫升）水吞咽试验来确定儿童误吸状态及经口喂养建议的临床实用性。
采用基于转诊的连续样本对一项诊断试验进行横断面评估。
城市三级医疗教学医院。
56名因吞咽评估而转诊的儿童（年龄范围2至18岁；平均13岁）。
吞咽功能纤维内镜检查（FEES）期间的误吸状态是用于与3盎司水吞咽试验结果进行比较的客观标准。
22名（39.3%）参与者通过了3盎司试验，34名（60.7%）未通过。预测FEES期间误吸状态的敏感性 = 100.0%，特异性 = 51.2%，假阳性率 = 48.4%。根据FEES结果识别被认为经口摄入安全的个体的敏感性 = 100.0%，特异性 = 44.0%，假阳性率 = 56.0%。
如果通过了3盎司水吞咽试验，不仅可以给予稀液体，还可以给出泥状和固体食物质地的饮食建议，而无需进一步进行仪器吞咽困难评估。
3盎司水吞咽试验已被证明是一种对儿童口咽吞咽困难有用的临床筛查试验。
