Coordination of infants' suck-swallow-breathing patterns is integral to safe and efficient feeding. However, assessment of these patterns is difficult and often invasive, particularly in breast-fed infants less than 4 months of age. The aims of this study were to develop an ultrasound approach to visualize swallowing in term breast-feeding infants and to determine the accuracy of ultrasound imaging of swallowing compared to respiratory inductive plethysmography (RIP). On ultrasound, the breast milk bolus was observed as a predominantly echogenic area moving inferiorly. Of the 388 swallows detected with ultrasound, 379 correlated with the swallow apneas detected by RIP (R(2) = 0.98). The mean duration of the swallow was 0.63 +/- 0.06 s. Ultrasound imaging is a noninvasive accurate method for detection of swallowing by visualization of movement of the milk bolus through the pharyngeal area of a breast-feeding infant. These techniques may potentially provide useful information for infants experiencing breast-feeding difficulties.
协调婴儿的吸吮-吞咽-呼吸模式是安全和有效喂养的关键。然而，这些模式的评估很困难，通常具有侵入性，特别是在 4 个月以下的母乳喂养婴儿中。本研究的目的是开发一种超声方法来可视化足月母乳喂养婴儿的吞咽，并确定超声成像吞咽与呼吸感应体积描记法（RIP）相比的准确性。在超声下，母乳乳块被观察为主要呈等回声区域向下移动。在通过 RIP 检测到的 388 次吞咽中，有 379 次与 RIP 检测到的吞咽暂停相关（R²=0.98）。吞咽的平均持续时间为 0.63±0.06 秒。超声成像通过可视化母乳乳块通过母乳喂养婴儿的咽区的运动，是一种非侵入性、准确的检测吞咽的方法。这些技术可能为有母乳喂养困难的婴儿提供有用的信息。
