Abstract：
UNASSIGNED: Breastfeeding naturally enables the coordination of sucking, swallowing, and respiration patterns for safe feeding. When breastfeeding is not possible a feeding device that releases milk in response to intra-oral vacuum could potentially offer improved coordination of sucking, swallowing, and breathing patterns compared to conventional devices. The aim of the study is to evaluate the effect of a valved infant-bottle with an ergonomic teat compared to a standard infant-bottle.
UNASSIGNED: This unblinded randomized controlled trial focused on late preterm infants fed by bottle for at least three meals over the day, admitted to the Neonatal Unit of Sant\'Anna Hospital (Turin, Italy). Infants were randomized to be fed with a valved infant-bottle with an ergonomic teat (B-EXP arm) or with a standard infant-bottle (B-STD arm). Monitoring included a simultaneous synchronized recording of sucking, swallowing and respiration. The main outcome was the swallowing/breathing ratio.
UNASSIGNED: Forty infants (20 B-EXP arm; 20 B-STD arm) with a median gestational age of 35.0 weeks (IQR 35.0-36.0 weeks) completed the study. Four infants were censored for the presence of artifacts in the polygraphic traces. The median swallowing/breathing ratio was 1.11 (1.03-1.23) in the B-EXP arm and 1.75 (1.21-2.06) in the B-STD (p = .003). A lower frequency of swallowing events during the inspiratory phase of breathing was observed in B-EXP arm compared with B-STD arm (p = 0.013).
UNASSIGNED: The valved infant-bottle with an ergonomic teat improves the coordination of sucking-swallowing-respiration and limits the risk of inhalation reducing the frequency of swallowing during the inspiratory phase.

摘要：
■母乳喂养自然可以协调吸吮，吞咽,和安全喂养的呼吸模式。当母乳喂养是不可能的时，响应口腔内真空释放乳汁的喂养装置可能会改善吸吮的协调，吞咽,与传统设备相比，呼吸模式。该研究的目的是评估与标准婴儿瓶相比，具有符合人体工程学的奶嘴的带瓣膜婴儿瓶的效果。
这项非盲随机对照试验的重点是晚期早产儿，每天至少三餐用奶瓶喂养，入住圣安娜医院新生儿科(都灵，意大利）。婴儿被随机分配给带有符合人体工程学的奶嘴的带瓣膜的婴儿瓶（B-EXP臂）或标准的婴儿瓶（B-STD臂）。监测包括同时同步记录吸吮，吞咽和呼吸。主要结果是吞咽/呼吸比。
■40名中位胎龄为35.0周（IQR35.0-36.0周）的婴儿（20B-EXP臂；20B-STD臂）完成了研究。对四名婴儿进行了检查，以检查其在多晶硅痕迹中是否存在伪影。B-EXP组的中位吞咽/呼吸比为1.11（1.03-1.23），B-STD组为1.75（1.21-2.06）（p=.003）。与B-STD臂相比，B-EXP臂在呼吸吸气阶段吞咽事件的频率较低（p=0.013）。
■带人体工学奶嘴的带瓣膜婴儿瓶可改善吸吮-吞咽-呼吸的协调性，并限制吸入的风险，从而降低吸气阶段的吞咽频率。
