背景：最近的文献支持真空是从乳房中吸出乳汁不可或缺的理论，而不是乳房的蠕动压缩。目的：我们的目的是确定母乳喂养的婴儿是否可以从实验奶嘴中吸出母乳，该实验奶头设计为仅在施加真空时释放乳汁。方法：在母乳喂养和用实验奶头喂养期间同时记录颏下超声图像和口腔内真空测量结果。结果：婴儿将乳头和奶头放置在与乳头硬软相似的距离处。当舌头降低时，腭交界处（4.7 毫米与 5.3 毫米）。当舌头降低时，乳头和奶头均匀地扩张，尽管乳头扩张得比奶头大（3.1 毫米对 1.5 毫米）。应用于乳房的基线（-31 毫米汞柱与-12 毫米汞柱）和峰值真空（-122 毫米汞柱与-67 毫米汞柱）均显着高于乳头。结论：母乳喂养的婴儿能够仅使用真空吸奶器从乳头吸出乳汁，舌头运动与母乳喂养相似。该证据支持这样的理论：真空是从乳房中排出乳汁的关键因素。 (C) 2011 Elsevier Ireland Ltd. 保留所有权利。
Background: Recent literature supports the theory that vacuum is integral to the removal of milk from the breast rather than peristaltic compression of the breast.Aim: We aimed to determine if breastfed infants could remove breast milk from an experimental teat designed to release milk only when a vacuum is applied.Methods: Submental ultrasound images and intra-oral vacuum measurements were recorded simultaneously during both a breastfeed and a feed with the experimental teat.Results: Infants placed the nipple and teat a similar distance from the nipple hard-soft palate junction when the tongue was lowered (4.7 mm vs 5.3 mm). As the tongue lowered the nipple and teat expanded evenly although the nipple expanded more than the teat (3.1 mm vs 1.5 mm). Both baseline (-31 mm Hg vs -12 mm Hg) and peak vacuum (-122 mm Hg vs -67 mm Hg) applied to the breast were significantly higher than for the teat.Conclusion: Breastfed infants are able to remove milk from a teat using only vacuum with a similar tongue movement to that of breastfeeding. This evidence supports the theory that vacuum is a critical factor in the removal of milk from the breast. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
