摘　　要：目的 总结婴幼儿毛细支气管炎的肺部超声表现,探讨肺超声评分(LUS)评估毛细支气管炎病情严重程度的临床价值。方法 选取诊断为毛细支气管炎82例患儿临床资料,所有患儿均于入院6 h内行双肺超声检查并进行LUS,同时给予胸部X线检查(CXR),比较肺超声与CXR的阳性征象显示率。根据患儿临床症状对病情严重程度进行分级,分析LUS与病情严重程度的关系。结果 82例患儿中,77例肺部超声存在阳性征象,最常见为胸膜线异常(75.3%)及胸膜下局灶性肺实变(67.5%),阳性征象显示率93.9%,CXR阳性征象显示率62.1%,两者比较差异有统计学意义(P<0.05)。不同临床分级组间肺超声评分差异有统计学意义,与临床分级呈正相关(rS=0.851,P<0.01)。结论 肺超声对婴幼儿毛细支气管炎具有诊断价值,主要特征表现为胸膜下局灶性肺实变,LUS可作为评估病情严重程度的工具。Objective To evaluate the clinical value of lung ultrasound score(LUS) in the severity of bronchiolitis in infants and young children. Methods The clinical data of 82 children diagnosed with bronchiolitis in our hospital were selected. All children received lung ultrasound examination and LUS within 6 hours after admission, and chest X-ray examination(CXR) was performed at the same time. The positive signs of lung ultrasound and CXR were compared. According to the clinical symptoms of children, the severity of the disease was graded, and the relationship between LUS and the severity of the disease was analyzed. Results Among the 82 cases, 77 cases had positive lung ultrasound signs, the most common of which were abnormal pleural line(75.3%) and subpleural focal lung consolidation(67.5%), the positive sign display rate of 93.9% and CXR positive sign display rate of 62.1%, the difference between the two was statistically significant(P<0.05). The difference of lung ultrasound scores among different clinical grades was statistically significant, which was positively correlated with clinical grades(rS=0.851, P<0.01). Conclusions Lung ultrasound is valuable in the diagnosis of infantile bronchiolitis, which is mainly characterized by subpleural focal lung consolidation. LUS can be used as a tool to evaluate the severity of the disease.
