本研究采用与吞咽荧光检查（VFES）的比较，以检查100 ml水吞咽试验（WST）评估吞咽功能障碍的有效性。59例临床疑似吞咽困难的连续门诊患者（15例女性，44例男性）入组本研究。每例受试者接受100 ml WST，随后进行VFES。获得了吞咽速度和窒息迹象（咳嗽和湿哑的声音）的数据。分析结果显示，49名受试者在100 ml WST中有异常吞咽速度（< 10 ml/s），其中47名被VFES确定为吞咽困难。在10名吞咽速度正常（> 10 ml/s）的参与者中，8名被VFES诊断为吞咽困难。值得注意的是，14名参与者在100 ml WST中窒息，其中11人在VFES中表现出吸入或穿透。在WST中没有窒息的45名参与者中，12名在VFES中显示吸入或穿透。吞咽速度检测吞咽功能障碍的敏感性为85.5%，特异性为50%。此外，使用100 ml WST中的窒息或湿马声作为预测吸入存在的唯一因素的敏感性为47.8%，而特异性为91.7%。因此，本研究得出结论，吞咽速度是识别吞咽功能障碍风险患者的敏感指标。此外，100 ml WST中的窒息可能是后续抽吸的潜在特异性指标。
This study used comparison with videofluoroscopic examination of swallowing (VFES) to examine the validity of a 100-ml water swallowing test (WST) in assessing swallowing dysfunction. Fifty-nine consecutive outpatients (15 females, 44 males) with clinically suspected dysphagia were enrolled in this study. Each subject underwent a 100-ml WST followed by VFES. Data was obtained on swallowing speed and signs of choking (coughing and a wet-hoarse voice). The analytical results revealed that 49 subjects had abnormal swallowing speeds (< 10 ml/s) in the 100-ml WST, and 47 of them were identified as having dysphagia by VFES. Among the ten participants with normal swallowing speed (> 10 ml/s), eight were diagnosed with dysphagia by VFES. Notably, 14 participants choked in the 100-ml WST, 11 of whom exhibited aspiration or penetration in VFES. Among the 45 participants without choking in WST, 12 displayed aspiration or penetration in VFES. The sensitivity of swallowing speed in detecting the swallowing dysfunction was 85.5%, and the specificity was 50%. Moreover, the sensitivity of using choking or wet-horse voice in the 100-ml WST as the sole factor for predicting the presence of aspiration was 47.8%, while the specificity was 91.7%. Therefore, this study concluded that swallowing speed is a sensitive indicator for identifying patients at risk for swallowing dysfunction. Moreover, choking in the 100-ml WST may be a potential specific indicator for followup aspiration.
