Nasal resistance (Rn) and total airways resistance (RAW) during nose breathing were measured in two groups of preterm infants. One group had been fed by nasogastric tube during the neonatal period, while the other had received only orogastric or bottle feeds. There were no significant differences in either Rn or RAW between the two groups, which suggests that for these infants a history of nasogastric tube feeding had no adverse effect on subsequent respiratory function. The acute effects of the nasogastric tube (NGT) were assessed by measuring Rn and RAW with and without the NGT in situ. A significant increase on both Rn and RAW occurred when the NGT was in situ, particularly in white infants, and when the NGT was passed through the larger of the two nostrils.
在两组早产儿中测量了经鼻呼吸时的鼻阻力（Rn）和总气道阻力（RAW）。一组在新生儿期通过鼻胃管喂养，而另一组仅接受口胃喂养或奶瓶喂养。两组之间的Rn或RAW均无显著差异，这表明对于这些婴儿，鼻胃管喂养史对随后的呼吸功能没有不利影响。通过在鼻胃管在位和不在位的情况下测量Rn和RAW来评估鼻胃管（NGT）的急性影响。当鼻胃管在位时，Rn和RAW均显著增加，尤其是在白人婴儿中，并且当鼻胃管通过两个鼻孔中较大的那个时。
