To comprehensively and quantitatively assess the process of lung liquid clearance using the lung ultrasound score. This study is to evaluate the whole healthy lungs of neonates during the first 24 h.
Lung ultrasound was performed in neonates with no respiratory symptoms within 3 h after birth, and scans were then repeated at 6 hours and 24 hours, respectively. The entire chest wall was divided into 12 regions. The lung ultrasound scores of the anterior, posterior, upper, and lower regions and sum of all regions were calculated according to the ultrasound pattern of each region examined.
The total lung ultrasound score decreased gradually during the first 24 h, with the total lung ultrasound score at 6 h being significantly lower than that at <3 h ( < 0.05). At <3 h, B-lines were more abundant in the posterior chest than in the anterior chest ( < 0.05). At <3 h, B-lines were more abundant in the posterior chest than in the anterior chest ( < 0.05). At <3 h, B-lines were more abundant in the posterior chest than in the anterior chest (.
Changes in the lung ultrasound score may quantitatively reflect the characteristics of different regions and processes of lung liquid clearance during the first 24 h.
使用肺部超声评分全面、定量评估肺液清除过程。本研究旨在评估出生后 3 小时内无呼吸系统症状的新生儿整个健康肺部。
对新生儿进行肺部超声检查，分别于出生后 6 小时和 24 小时进行重复扫描。整个胸壁被分为 12 个区域。根据每个检查区域的超声模式，计算前、后、上、下区域的肺部超声评分以及所有区域的总和。
在出生后 24 小时内，总肺部超声评分逐渐下降，6 小时的总肺部超声评分明显低于<3 小时（<0.05）。在<3 小时时，后胸部的 B 线比前胸部更丰富（<0.05）。在<3 小时时，后胸部的 B 线比前胸部更丰富（<0.05）。
肺部超声评分的变化可能定量反映出生后 24 小时内不同区域和肺液清除过程的特征。
