OBJECTIVE
To evaluate the diagnostic value of lung ultrasound (LUS) for childhood community-acquired pneumonia (CAP).
METHODS
A case-control study was conducted among pediatric outpatients with suspected CAP who underwent LUS examination. Baseline data such as clinical manifestations were collected. Diagnostic performance was assessed using Pearson Chi-square tests, with CT scans as the gold standard. Specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV) of LUS were analyzed.
RESULTS
The study included 246 patients who underwent both LUS and CT (observation group) and 111 controls who received concurrent chest x-ray and CT within one week. LUS demonstrated significantly higher sensitivity (91.30% vs. 75.00%, < 0.001) than chest x-ray group, while specificity, PPV, and NPV showed no statistically significant ( > 0.05).
CONCLUSION
LUS exhibits high concordance with CT in pediatric CAP diagnosis, demonstrating excellent screening and diagnostic value for childhood CAP.
目的
评估肺部超声（LUS）对儿童社区获得性肺炎（CAP）的诊断价值。
方法
对疑似CAP的儿科门诊患者进行LUS检查，开展病例对照研究。收集临床表现等基线数据。以CT扫描作为金标准，采用Pearson卡方检验评估诊断性能。分析LUS的特异性、敏感性、阳性预测值（PPV）和阴性预测值（NPV）。
结果
该研究纳入了246例同时接受LUS和CT检查的患者（观察组）以及111例在一周内同时接受胸部X线和CT检查的对照组。LUS的敏感性显著高于胸部X线检查组（91.30% 对75.00%，<0.001），而特异性、PPV和NPV无统计学差异（>0.05）。
结论
LUS在儿科CAP诊断中与CT具有高度一致性，对儿童CAP具有出色的筛查和诊断价值。
