目的：在非实验室、临床条件下，观察13例健康早产儿(月经后32.7~37.1周)一次性、激光切割、慢流乳头对呼吸和乳汁摄取的影响。方法：在慢流和标准流乳头喂养期间，采用综合鼻气流量和容量校准奶瓶测量分钟通气量和总乳汁转移量。采用Wilcoxon符号列检验来检验乳头类型对两种结果的影响。结果：慢流和标准流乳头的喂奶前分钟通气量在吸吮爆发时显著降低，并在吸吮爆发中断时恢复到基线值。在慢流和标准流乳头之间，没有发现每分钟通气量(p>；.40)或总乳汁转移(p=.58)的差异。结论：一次性使用的慢流和标准流乳头的主要结果没有差异，可能反映了同一制造商生产的乳头特性的差异。未来对一次性使用和可重复使用乳头产品的效果进行调查，以更好地指导临床护理期间的乳头选择是有必要的。
Purpose: Single-use, laser-cut, slow-flow nipples were evaluated for their effect on respiration and milk ingestion in 13 healthy preterm infants (32.7-37.1 weeks postmenstrual age) under nonlaboratory, clinical conditions.Method: The primary outcomes of minute ventilation and overall milk transfer were measured by using integrated nasal airflow and volume-calibrated bottles during suck bursts and suck burst breaks during slow-flow and standard-flow nipple bottle feedings. Wilcoxon signed-ranks tests were used to test the effect of nipple type on both outcomes.Results: Prefeeding minute ventilation decreased significantly during suck bursts and returned to baseline values during suck burst breaks across both slow-flow and standard-flow nipples. No differences were found in minute ventilation (p > .40) or overall milk transfer (p = .58) between slow-flow and standard-flow nipples.Conclusions: The lack of difference in primary outcomes between the single-use slow-flow and standard-flow nipples may reflect variability in nipple properties among nipples produced by the same manufacturer. Future investigations examining the effect of both single-use and reusable nipple products are warranted to better guide nipple selection during clinical care.
