新生儿呼吸窘迫综合征X线与CT表现及诊断价值

Manifestations and diagnostic value of X-ray and CT in neonatal respiratory distress syndrome

目的探讨新生儿呼吸窘迫综合征(neonatal respiratory distress syndrome,NRDS)X线与CT表现及诊断价值。方法选定笔者医院2017年8月—2019年9月收诊的96例NRDS患儿临床资料进行回顾性研究,先后接受X线检查及CT检查,比较两种不同检查方法对NRDS患儿的白色肺、支气管充气征、肺透亮度降低、粗大融合的颗粒阴影、细颗粒与网点影、肺感染、肺出血的检出率,对比家长对检查手段的诊断满意率。结果检测结束时CT诊出白色肺、肺透亮度降低、粗大融合颗粒阴影的检出率与X线比较,差异无统计学意义(P>0.05);且家长对CT及X线的诊断质量满意率基本相当(P>0.05)。X线对支气管充气征、细颗粒与网点影的检出率均高于CT检查(P<0.05),其肺感染、肺出血的检出率均低于CT诊断(P<0.05)。结论针对NRDS患儿,CT、X线的诊断作用可互为补充,联合应用下可有效提高患儿的诊断质量,准确检出其并发症情况。

Objective To explore the manifestations and diagnostic value of X-ray and CT in neonatal respiratory distress syndrome(NRDS).Methods The clinical data of 96 patients with NRDS admitted to the hospital from August 2017 to September 2019 were selected for retrospective study.X-ray examination and CT examination were performed successively.The detection rates of white lung,air bronchogram,reduced lung transparency,bulky fused particle shadows,fine particle and net-point shadow,lung infection and lung hemorrhage in NRDS patients were compared between two different examination methods,and the diagnostic satisfaction rate of parents towards examination methods was compared.Results At the end of the detection,there were no significant differences in the detection rates of white lung,reduced lung transparency and bulky fused particle shadows by CT compared with those by X-ray(P>0.05).And the parents’satisfaction rate towards diagnostic quality of CT or X-ray was basically the same(P>0.05).The detection rates of air bronchogram and fine particle and net-point shadow by X-ray were higher than those by CT examination(P<0.05),and the detection rates of lung infection and lung hemorrhage were lower than those by CT examination(P<0.05).Conclusion For NRDS patients,the diagnostic effects of CT and X-ray can complement each other,and combined application can effectively improve the diagnostic quality of children patients and accurately detect the complications.
