背景：虽然多年来一直推荐使用正畸乳头来补充母乳喂养的婴儿，但尚不清楚这种乳头是否适合母亲希望母乳喂养的住院早产儿。目的：描述和比较作为自身对照的早产儿对两种喂养方式的短期生理反应，母乳喂养和奶瓶喂养的正畸乳头。方法：样本由8名早产儿组成，平均出生体重为1370克，出生时平均胎龄为30.2周，作为母乳喂养和奶瓶喂养的对照组。在母乳喂养和奶瓶喂养的过程中，对吸吮、呼吸和血氧饱和度等因变量进行了无创测量，并记录在测谎仪上。对14次母乳喂养和15次奶瓶喂养的数据进行了定量和定性分析。结果：与奶瓶喂养相比，在母乳喂养期间，婴儿在吸吮期间呼吸更多，并且在母乳喂养期间更少发生氧饱和度下降，这在统计上有显著差异。在一些使用正畸乳头进行奶瓶喂养的婴儿中，观察到与有组织呼吸相关的特征吮吸波形。结论：正畸乳头是部分早产儿母乳喂养的补充。需要进一步的研究来检验长期结果。
Background:Although the orthodontic nipple has been recommended for many years to supplement breast-feeding infants, it is not known if this nipple is suitable for hospitalized preterm infants whose mothers wish to breast-feed.Objectives:To describe and compare short-term physiologic responses of preterm infants serving as their own controls for two feeding methods, breast-feeding and bottle-feeding with the orthodontic nipple.Method:The sample consisted of eight preterm infants, mean birth weight of 1,370 grams and mean gestational age at birth of 30.2 weeks' gestation, who served as their own controls for breast-and bottle-feeding sessions. The dependent variables, sucking, breathing, and oxygen saturation, were measured noninvasively throughout breast-and bottle-feeding sessions and recorded on a polygraph. Data were analyzed quantitatively and qualitatively for 14 breast-feeding sessions and 15 bottle-feeding sessions.Results:Statistically significant differences were found in that infants breathed more during sucking bursts for breast-feeding sessions when compared to bottle-feeding sessions and had fewer episodes of oxygen desaturation during breast-feeding. A characteristic sucking waveform associated with organized breathing was observed for some infants during bottle-feeding with the orthodontic nipple.Conclusions:These data suggest that the orthodontic nipple is appropriate for supplementing breast-feeding for some preterm infants. Further research is needed to examine longterm outcomes.
