A previous article from our group presented data on normal swallowing as assessed during simultaneous manometry and flexible endoscopic evaluation of swallowing (FEES). Because penetration and aspiration events were identified in healthy adults, the question arose, could the presence of the manometric catheter confound normal FEES findings? Thus, a follow-up study was designed to address the effects of catheter condition on healthy older adults as assessed during FEES.
Twenty older adults (mean, 78.9 years of age) participated. The participants each contributed 28 swallows, affording a study total of 560 swallows for analyses.
The older adults demonstrated penetration on 82 (15%) and aspiration on 18 (3%) of 545 swallows. The numbers of participants who had penetration and aspiration during the study protocol were 75% and 30%, respectively. The older adults demonstrated both penetration and aspiration events irrespective of the presence of a catheter; whether they were drinking milk, water, or barium; whether the bolus was 5 or 10 mL; and whether they took the bolus via syringe or self-administered the bolus with a cup. However, significantly more aspiration was found on thin liquids than on puree or solids.
Endoscopic data on normal swallowing physiology were generated. These may serve as an accurate benchmark for clinicians and researchers in the interpretation of dysphagia.
我们团队之前的一篇文章展示了在同步测压和吞咽功能的软性内镜评估（FEES）过程中对正常吞咽的评估数据。由于在健康成年人中发现了渗透和误吸事件，因此出现了一个问题，测压导管的存在是否会混淆正常的FEES检查结果？因此，设计了一项后续研究，以探讨在FEES检查过程中导管状况对健康老年人的影响。
20名老年人（平均年龄78.9岁）参与了研究。每位参与者进行28次吞咽，共计560次吞咽用于分析。
在545次吞咽中，老年人出现82次（15%）渗透和18次（3%）误吸。在研究过程中出现渗透和误吸的参与者比例分别为75%和30%。无论是否存在导管、饮用牛奶、水还是钡剂、推注量为5毫升还是10毫升，以及是通过注射器推注还是用杯子自行饮用，老年人都会出现渗透和误吸事件。然而，发现稀薄液体的误吸明显多于泥状食物或固体食物。
生成了关于正常吞咽生理学的内镜检查数据。这些数据可为临床医生和研究人员解释吞咽困难提供准确的基准。
