Foreign body aspiration (FBA) has a wide clinical spectrum, patients may be asymptomatic or present with cardiopulmonary arrest. Radiological imaging methods are used in addition to history and physical examination findings for certain diagnosis. Lung ultrasonography (LUS), whose usage area is increasing year by year, can be included in these. This study aimed to investigate ultrasonography findings in FBA and hypothesized that LUS may have a standard place in FBA diagnosis.
Patients who administered to the pediatric emergency department between August 2019-August 2021, considered according to the clinical findings and physical examination possible FBA, and who undergone rigid bronchoscopy by pediatric surgery were included in the study.
Thirty-two patients were included in the study. According to the results of bronchoscopy, FBA was detected in 25 patients. The most common finding in radiography was hyperinflation on one side, while LUS findings were confluent-B lines in eight patients, barcode-sign in five patients, pleural line abnormalities in two patients, and pleural consolidation in two patients.
This study is the first study aiming to evaluate LUS findings in FBA to the best of our knowledge. The B-lines, barcode sign, pleural line abnormalities and consolidation are seen findings in LUS of the patients with FBA. Although it is far from replacing chest radiography in these patients, it is possible to say that it has an equivalent value with chest radiography.
异物吸入（FBA）具有广泛的临床特征，患者可能无症状，也可能出现心肺骤停。除了病史和体格检查结果外，还会使用放射影像学方法进行明确诊断。肺部超声（LUS）的应用范围逐年增加，也可用于诊断。本研究旨在探讨 FBA 的超声表现，并假设 LUS 在 FBA 诊断中可能具有标准地位。
本研究纳入了 2019 年 8 月至 2021 年 8 月期间在儿科急诊就诊的疑似 FBA 的患者，这些患者根据临床发现和体格检查结果，经小儿外科行硬性支气管镜检查。
本研究共纳入 32 例患者。根据支气管镜检查结果，25 例患者被诊断为 FBA。放射学检查最常见的结果是单侧过度充气，而 LUS 的表现为 8 例患者的融合 B 线、5 例患者的条码征、2 例患者的胸膜线异常和 2 例患者的胸膜实变。
据我们所知，这是第一项旨在评估 LUS 在 FBA 中的表现的研究。B 线、条码征、胸膜线异常和实变是 FBA 患者 LUS 的常见表现。尽管在这些患者中，它远不能替代胸部 X 线摄影，但可以说它与胸部 X 线摄影具有同等价值。
