婴儿吸吮科学

阅读时间：

成功的母乳喂养依赖于母亲与宝宝的互动。为了理解和解决婴儿吸吮问题，首先要理解泌乳、乳汁排出的解剖学和生理学原理。美德乐及西澳洲大学的顶尖专家们对哺乳期乳房解剖学进行了研究（Ramsay et al，2005 ）。这场突破性的研究对原有的认识提出了质疑，进而改写了许多教科书的内容。随后，将这项新成果应用到探索哺乳时婴儿吸出乳汁的研究中。

吸吮周期

西澳洲大学通过使用超声波和负压测量方法，探究了哺乳过程中的婴儿吸吮。

在一个吸吮周期过程中，开始负压处于基线水平，在舌向下运动时，口腔负压增加，当舌抵达最低点时，口腔负压达到峰值。在舌向下时，母乳开始流出。然后舌头上升，重新回到基线 - 母乳停止流出。

重大发现

负压在乳汁排出过程中发挥着重要作用
舌头并不没有明显的“滚动挤压”
乳头没有有明显的被压扁的迹象
乳头前端没有顶到软/硬颚连接处

Tongue movement and intra-oral vacuum in breastfeeding infants

The mechanism by which the breastfeeding infant removes milk from the breast is still controversial. It is unclear whether the infant uses predominantly intra-oral vacuum ...
