肺部超声在肺部疾病应用中具有较高的敏感性和特异性，并且明显降低了儿童，尤其是新生儿的辐射暴露，使其在儿童疾病诊断、治疗和预后中都得到了较为广泛的应用。在急诊和重症监护室，肺部超声甚至可代替X线胸片作为胸部病变的常规检查方法。但儿童肺部超声的研究仍落后于成人，且缺乏儿童肺部超声检查的标准流程及规范。本文主要对肺部超声在儿童肺部疾病的应用现状进行综述。“,”Lung ultrasound has been proven to have high sensitivity and specificity in the application of lung diseases, and significantly reduces the radiation exposure of children, especially in newborns, which makes it widely used in diagnosis, treatment and prognosis of childhood disease.In emergency and intensive care units, lung ultrasound can even replace chest radiographs as a routine examination method for chest lesions.However, the research of children′s lung ultrasound still falls behind the development of adult ultrasound, and there is a lack of standard procedures and specifications for children′s lung ultrasound.Therefore, this study mainly reviewed the research status of children′s lung ultrasound.
