The goals of this article are to explore the use of textured thin liquids for dysphagic patients who require thickened liquids and to illustrate their impact on hydration and patient satisfaction.
A retrospective evaluation of textured thin liquids was completed using patient data looking at laboratory values relevant to the detection of dehydration (blood urea nitrogen, creatinine, sodium) and patient satisfaction (using a clinician-generated questionnaire) on different modified liquid textures. In addition, the viscosity for all liquids was tested using a rheometer.
Measurements show that the viscosity of the textured thin liquids examined in this pilot study are significantly lower than the viscosity of nectar-thick liquids and fall within the "thin" category as defined by the National Dysphagia Diet guidelines. Patients on honey- and nectar-thick liquids had laboratory values signifying dehydration, whereas those receiving the textured thin liquid consistency were within the normal range for all laboratory values. Importantly, when consuming textured thin liquids, patients reported significant improvement in their satisfaction related to their thirst.
The results of this pilot study highlight the consequences of common thickened liquid dietary recommendations and of the potentially beneficial clinical application of textured thin liquids for patients with dysphagia as well as the need for future prospective research.
本文旨在探讨纹理稀薄液体在需要浓稠液体的吞咽困难患者中的应用,并说明其对水合作用和患者满意度的影响。
使用患者数据对纹理稀薄液体进行回顾性评估,观察与脱水检测相关的实验室值(血尿素氮、肌酐、钠)和不同改良液体质地的患者满意度(使用临床医生生成的问卷)。此外,使用流变仪测试所有液体的粘度。
测量结果表明,本研究中检查的纹理稀薄液体的粘度明显低于花蜜状浓稠液体的粘度,并且符合国家吞咽障碍饮食指南定义的“稀薄”类别。接受蜂蜜和花蜜状浓稠液体的患者的实验室值表明存在脱水,而接受纹理稀薄液体的患者的所有实验室值均在正常范围内。重要的是,当患者食用纹理稀薄液体时,他们报告在与口渴相关的满意度方面有显著改善。
这项初步研究的结果突出了常见浓稠液体饮食建议的后果,以及纹理稀薄液体对吞咽困难患者的潜在有益临床应用,需要进一步进行前瞻性研究。
