To evaluate the effect of body position on the cardiorespiratory indicators of preterm newborns receiving nasal continuous positive airway pressure (CPAP).
Analytical, observational, prospective, cross-sectional, randomised crossover study was carried out on sixteen newborns that received nasal CPAP. The infants had a mean gestational age of 29.7 ± 2 weeks and birthweight of 1353 ± 280 g. Cardiorespiratory indicators (respiratory rate, heart rate and oxygen saturation) were evaluated in each infant in the supine, prone and right and left lateral decubitus positions at intervals of 10 min over a period of 60 min.
The cardiorespiratory indicators were similar and within the normal range in the four decubitus positions. There was no difference in respiratory or heart rate between body positions. Although they showed desirable values, oxygen saturation was significantly lower in left lateral decubitus (96.6 ± 1.7%) when compared to the supine (97.1 ± 1.3%) and prone positions (97.4 ± 1.1%) (p = 0.00) and was also significantly lower in right lateral decubitus (96.9 ± 1.4%) when compared to the prone position (p = 0.00).
We found no preferential decubitus position for preterm newborns receiving nasal CPAP, the supine position may be a choice, but the left and right lateral positions were less advantageous in terms of oxygen saturation.
评估体位对接受经鼻持续气道正压通气（CPAP）的早产儿心肺呼吸指标的影响。
对 16 名接受经鼻 CPAP 的早产儿进行了分析性、观察性、前瞻性、交叉随机研究。婴儿的平均胎龄为 29.7±2 周，出生体重为 1353±280g。在 60 分钟的时间内，每隔 10 分钟评估每个婴儿在仰卧位、俯卧位和右侧、左侧卧位时的心肺呼吸指标（呼吸频率、心率和氧饱和度）。
四种卧位的心肺呼吸指标相似且均在正常范围内。体位对呼吸或心率无差异。虽然氧饱和度值理想，但与仰卧位（97.1±1.3%）和俯卧位（97.4±1.1%）相比，左侧卧位（96.6±1.7%）显著降低（p=0.00），与俯卧位相比，右侧卧位（96.9±1.4%）也显著降低（p=0.00）。
我们没有发现接受经鼻 CPAP 的早产儿有优先的卧位，仰卧位可能是一种选择，但左侧和右侧卧位在氧饱和度方面的优势较小。
