We attempted to determine whether differences in milk composition or flow rate are the primary determinants in altering breathing pattern during nipple-feeding. In the first phase of the study, 15 neonates were studied during breast-feeding and bottle-feeding; in the second phase, 15 were evaluated during bottle-feeding of expressed human milk and formula. A reduction in inspiratory duration was observed with all feeding regimens. Moreover, significant prolongation in expiratory duration and reduction in breathing frequency were observed during bottle-feeding of formula and expressed human milk (compared with control); these effects were greater with formula feeding. Higher sucking frequency was observed during breast-feeding compared with bottle-feeding; no difference in suckling frequency or sucking pressure was observed between bottle-feeding of expressed human milk and formula. We conclude that most of the differences in sucking and breathing patterns between breast- and bottle-feeding can be attributed to nutrient delivery rather than nutrient composition.
我们试图确定乳汁成分或流速的差异是否是改变乳头喂养期间呼吸模式的主要决定因素。在研究的第一阶段，对15名新生儿进行母乳喂养和奶瓶喂养研究；在第二阶段，对15名新生儿进行挤出人乳和配方奶奶瓶喂养评估。所有喂养方案均观察到吸气持续时间缩短。此外，在配方奶和挤出人乳奶瓶喂养期间（与对照组相比）观察到呼气持续时间显著延长和呼吸频率降低；配方奶喂养的这些影响更大。与奶瓶喂养相比，母乳喂养期间观察到更高的吸吮频率；挤出人乳和配方奶奶瓶喂养之间的吸吮频率或吸吮压力没有差异。我们得出结论，母乳喂养和奶瓶喂养之间吸吮和呼吸模式的大多数差异可归因于营养物质输送而非营养成分。
