本研究的目的是比较48个足月婴儿的吸吮力学与四种不同的乳头单位：Gerber新生儿（Gerber产品公司，弗里蒙特，密歇根州），Playtex（Playtex Products，韦斯特波特，康涅狄格州），Evenflo（Evenflo Products Co.，Canton，Ga.），在出生后24小时，婴儿被随机分配到其中一个乳头单元，并使用该乳头单元进行两次研究。使用定制的数据采集系统测量和记录以下变量：口内抽吸、抽吸频率、功、功率、奶流量、每次抽吸的奶量和氧饱和度。虽然在口内抽吸、抽吸频率、功率和氧饱和度方面，乳头单位之间没有统计学显著差异，但数据显示，Playtex乳头单位伴随着更高的峰值奶流量和更大的每次抽吸奶量（p < 0.05）。婴儿用Playtex奶嘴喂养的方式与其他奶嘴不同，我们的研究结果表明，与其他奶嘴相比，Playtex奶嘴允许更大的乳汁流量，以响应类似的吸力，功和功率。与Playtex组相比，Gerber NUK组的平均每次吸吮总功显著更低，此外，Gerber NUK奶嘴的每单位体积吸吮总次数更高，摄入特定量乳汁的总时间更长。
The purpose of this study was to compare the mechanics of sucking for 48 term infants with four different nipple units: Gerber Newborn (Gerber Products Company, Fremont, Mich.), Playtex (Playtex Products, Westport, Conn.), Evenflo (Evenflo Products Co., Canton, Ga.), and Gerber NUK, At 24 hours after birth, infants were assigned randomly to one of the nipple units and were studied twice with that nipple unit. A customized data acquisition system was used to measure and record the following variables: intraoral suction, sucking frequency, work, power, milk flow, milk volume per suck, and oxygen saturation. Although no statistically significant differences among the nipple units were noted for intraoral suction, sucking frequency, power, and oxygen saturation, the data revealed that the Playtex nipple unit was accompanied by higher peak milk flow and greater volume of milk per suck (p < 0.05). Infants fed differently with the Playtex nipple than they did with the other nipples, Our findings indicate that the Playtex nipple permits a greater milk flow in response to similar amounts of suction, work, and power where compared with others. The mean total work per suck was significantly lower in the Gerber NUK group compared with the Playtex group, In addition, the total number of sucks per volume ingested was higher, and the total time to ingest a specific quantity of milk was longer for the Gerber NUK nipple.
