In this study, the authors examined mean volumes of discrete sips performed by healthy adults from straws varying in internal diameter.
Forty healthy adults sipped water from each of 7 straws varying in internal diameter (0.65-5.00 mm). Bolus volumes associated with 3 discrete sips were recorded under each sip condition.
Straw diameter had a significant effect on bolus size, with the smallest diameter straws eliciting the smallest bolus volumes. Bolus volumes did not vary according to age or sex. Considerable intersubject variation was observed, particularly for the straws with the largest diameters. Intrasubject variability across 3 trials was minimal.
The findings support the hypothesis that narrower straw diameters are associated with smaller bolus volumes in healthy adults. Additional study is needed to determine whether individuals with dysphagia demonstrate similar patterns of bolus size associated with straws varying in internal diameter and whether such variations have clinical benefit.
本研究旨在考察健康成年人通过不同内径吸管吸啜的离散小口的平均容量。
40 名健康成年人分别从内径（0.65-5.00mm）不同的 7 根吸管中吸啜水。在每种吸啜条件下记录与 3 个离散小口相关的食团体积。
吸管直径对食团大小有显著影响，最小直径的吸管产生的食团体积最小。食团体积与年龄或性别无关。观察到受试者间的差异很大，特别是对于最大直径的吸管。3 次试验的个体内变异性最小。
研究结果支持这样的假设，即较细的吸管直径与健康成年人较小的食团体积有关。需要进一步研究以确定是否吞咽困难的个体表现出与内径不同的吸管相关的类似食团大小模式，以及这种变化是否具有临床益处。
