The aim of this study was to obtain lower airway dimensions in children by means of computed tomography (CT).
Chest CT scans from 195 pediatric patients (118 boys/77 girls) aged 0.04-15.99 years were analyzed. Tracheal and bronchial lengths, anterior-posterior and lateral diameters, as well as cross-sectional area were assessed at the following levels: mid trachea, right proximal and distal bronchus, proximal bronchus intermedius, and left proximal and distal bronchus. Mediastinal angles of tracheal bifurcation were measured. Data were analyzed by means of linear and polynomial regression plots.
The strongest correlations were found between tracheal and bronchial diameters and age as well as between tracheal and bronchial lengths and body length. All measured airway parameters correlated poorly to body weight. Bronchial angles revealed no association with patient's age, body length, or weight.
This comprehensive anatomical database of lower airway dimensions demonstrates that tracheal and bronchial diameters correlate better to age, and that tracheal and bronchial length correlate better to body length. All measured airway parameters correlated poorly to body weight.
本研究的目的是通过计算机断层扫描（CT）获得儿童下气道尺寸。
分析了195例年龄在0.04至15.99岁之间的儿科患者（118名男孩/77名女孩）的胸部CT扫描图像。在以下层面评估气管和支气管的长度、前后径和横径以及横截面积：气管中部、右主支气管近端和远端、支气管中间段近端以及左主支气管近端和远端。测量气管分叉处的纵隔角。通过线性和多项式回归图分析数据。
发现气管和支气管直径与年龄之间以及气管和支气管长度与身长之间的相关性最强。所有测量的气道参数与体重的相关性较差。支气管角与患者的年龄、身长或体重均无关联。
这个关于下气道尺寸的综合解剖学数据库表明，气管和支气管直径与年龄的相关性更好，气管和支气管长度与身长的相关性更好。所有测量的气道参数与体重的相关性较差。
