42例新生儿肺透明膜病X线影像分析

目的:探讨新生儿肺透明膜病(hyaline membrane diseaas,HMD)X线影像特征。方法:对扬州市妇幼保健院新生儿病房42例确诊为HMD的患儿床边X线胸片进行分析,根据肺泡萎陷程度,HMD分为四级。结果:I级X线表现肺野透亮度略低,肺野内见细小颗粒影;II级X线表现肺野透亮度进一步降低,呈磨玻璃样改变,肺野内见密集分布均匀的细颗粒影,并见支气管充气征。III级X线表现肺内细颗粒影融合变大,边缘模糊,肺野透亮度明显降低,心膈模糊。IV级X线表现肺野密度均匀致密呈"白肺",心缘膈面完全消失。结论:HMD的X线影像具有特征性表现,X线胸片是诊断HMD的可靠检查方法。

Analysis of X-ray images for 42 cases of neonatal pulmonary hyaline membrane disease

Objective：To discuss X-ray image features of neonatal pulmonary hyaline membrane disease （hyaline membrane diseaas, HMD）. Methods ：42 cases in neonatal ward of our hospital and diagnosed as HMD were selected, and their bedside X-ray films were analyzed. According to the degree of alveolar collapse, HMD were divided into four levels. Results： The lung field X-ray image of the I level HMD showed a slightly low transparency, and tiny particle shadows were see. The transparency of the lung field in those with II level HMD was further reduced and showed a ground-glass opacity, there were densely and homogeneously distributed fine particle shadows in the lung field, and an air-filled bronchi also could be seen. The X-ray image of III level HMD showed fused fine particle shadows in the lung with a blurry edge, the lung field transparency was significantly reduced, and also the heart diaphragm was blurry. The X-ray image of III level HMD showed a ＂white lung＂ with an uniform density, and the diaphragmatic surface of the cardi- ac bonder completely disappeared. Conclusions： The X-ray image of HMD has the characteristic features, and the X-ray chest radio- graph is a reliable examination method in diagnosis of HMD.
