The present study aimed to provide normative data for nasal airway resistance in the newborn. Anterior rhinomanometry was performed on 17 full term Caucasian infants aged 1 to 4 days, birthweight 3100 to 4150 g. No sedation or decongestion was performed. Average unilateral nasal resistance was 4.86 kPa/l/s (SD = 2.41) at a pressure threshold of 75 Pa. Average nasal resistance calculated from the right and left side recordings was 2.14 kPa/l/s (SD = 0.77). This corresponds to 21.8 cm H2O/l/s (SD = 7.9). The nasal resistance of the newborn thus is approximately 10 times that of the adult.
本研究旨在提供新生儿鼻气道阻力的标准数据。对17名1至4日龄的足月高加索婴儿进行了前鼻测压，出生体重为3100至4150克。未进行镇静或减充血处理。在75帕的压力阈值下，平均单侧鼻阻力为4.86千帕/升/秒（标准差=2.41）。根据左右两侧记录计算出的平均鼻阻力为2.14千帕/升/秒（标准差=0.77）。这相当于21.8厘米水柱/升/秒（标准差=7.9）。因此，新生儿的鼻阻力约为成年人的10倍。
