摘要
目的研究肺超声(LUS)对儿童社区获得性肺炎(CAP)的诊断价值。方法对我院207例疑诊CAP的患儿行LUS和CXR检查,比较二者的诊断价值。结果儿童CAP的声像图特征是多重或融合B线,低回声区。LUS诊断CAP的敏感性94.8%,特异性94.2%;CXR诊断CAP的敏感性80.0%,特异性90.4%,敏感性有统计学意义(χ~2=13.08,P<0.01),特异性无统计学意义(χ~2=0.13,P>0.05)。结论 LUS对CAP的诊断准确性不低于CXR。LUS便捷、无辐射,是儿童CAP理想的影像学诊断方法。
Objective To investigate the diagnostic value of pulmonary ultrasound （LUS） in children with community acquired pneumonia （CAP）. Methods 207 cases of suspected CAP underwent LUS and CXR examination in our hospital, the diagnostic value were compared. Results The sonographic features of children with CAP are characterized by multiple or fused B lines with hypoechoic areas, sensitivity of LUS for CAP diagnosis was 94.8% and specificity was 94.2%; sensitivity of CXR for CAP diagnosis was 80%, specificity 90.4%, and sensitivity was statistically significant （x^2=13.08, P 〈 0.01）, specificity was not statistically significant （x^2=0.13, P 〉 0.05）. Conclusion The diagnostic accuracy of LUS for CAP is not less than CXR. LUS is an ideal imaging diagnostic method for CAP in children. It is convenient and free of radiation.
