To measure intraoral pressure and perioral movement in infants during breastfeeding (BF) and feeding with experimental teat (ET). The teat has a wide base, firm shaft and a valve at the base, such that milk flows only when the baby provides a hold pressure.
Twenty healthy term infants, between 1 and 8 months old, were enrolled in the study. Feeding sessions (BF and ET) were recorded using a digital video camera. During both BF and ET feeding sessions, recordings during feeding were taken of jaw and throat movements (n=20) as well as intraoral pressure (n=18). The efficiency of milk transfer and the angle of the mouth were also measured.
There was no significant difference in either the jaw or throat movements between BF and ET. The sucking burst pattern, the efficiency (ml min(-1)), and the angle of the mouth did not differ between both feeding methods. The intraoral negative pressure observed during ET was significantly smaller than that observed during BF.
There were no significant differences in perioral movements. Although the value was smaller, a hold pressure was observed during ET. From these results, the novel, ET may decrease BF problems related to bottle use.
测量婴儿在母乳喂养（BF）和使用实验奶嘴（ET）喂养时的口腔内压力和口周运动。奶嘴具有宽底座、坚固的轴和底部的阀门，只有当婴儿提供保持压力时，牛奶才会流动。
研究纳入了 20 名健康的足月婴儿，年龄在 1 至 8 个月之间。使用数字摄像机记录喂养过程（BF 和 ET）。在 BF 和 ET 喂养过程中，记录了下颌和喉咙运动（n=20）以及口腔内压力（n=18）。还测量了牛奶转移的效率和嘴巴的角度。
BF 和 ET 之间的下颌或喉咙运动没有显著差异。两种喂养方式的吸吮爆发模式、效率（ml/min）和嘴巴角度没有差异。在 ET 期间观察到的口腔内负压明显小于 BF 期间观察到的负压。
口周运动没有显著差异。尽管值较小，但在 ET 期间观察到保持压力。从这些结果来看，新型 ET 可能会减少与奶瓶使用相关的 BF 问题。
