Fourteen newborn babies of different gestational ages (33 to 40 weeks) but similar postnatal age (four to 19 days) were studied during bottle-feeding using real-time ultrasonography, combined with respiratory monitoring. Previously undescribed tongue movements and graded changes in the temporal relationships between tongue movements, swallowing and breathing were observed among infants of differing maturity. These were most marked in the least mature infants, but were occasionally seen in term infants. The results suggest that adequate neuromuscular co-ordination is more a function of gestational maturity than of postnatal sucking experience. The pattern of intraoral events for infants of differing maturity described in this study provides a framework for the study of feeding problems of term and preterm infants.
对14名不同孕周（33至40周）但出生后年龄相近（4至19天）的新生儿在奶瓶喂养期间进行了实时超声检查，并结合呼吸监测。在不同成熟度的婴儿中观察到了此前未描述过的舌部运动以及舌部运动、吞咽和呼吸之间时间关系的分级变化。这些在最不成熟的婴儿中最为明显，但足月婴儿中偶尔也会出现。结果表明，足够的神经肌肉协调更多地是孕周成熟度的函数，而非出生后的吸吮经验。本研究中描述的不同成熟度婴儿的口内事件模式为研究足月和早产婴儿的喂养问题提供了一个框架。
