目的:对35例高原肺水肿X线表现,按张氏分型,讨论其与病理生理改变的关系。方法:35例高原肺水肿病例,均摄X 线胸片,并进行血氧饱合度检测。结果:35例均有不同程度肺水肿表现,局限型16例、间质型6例、弥漫型7例、中央型6例。X线肺水肿表现与血氧饱和度关系紧密,SaO_2<50％ 12例中肺水肿呈弥漫型与中央型改变,SaO_2<73％23例中呈局限型与间质型改变,其中局限型16例。缺氧严重程度与X 线表现分型关系明显也与病理改变关系密切,同时也反应了病变发展的程度与阶段。结论:重视X 线表现征象与及时诊断,对临床治疗有明显意义。
OBJECTIVE: To investigate the X-ray findings of 35 cases of high altitude pulmonary edema according to Zhang’s classification and to discuss its relationship with pathophysiological changes. Methods: 35 cases of high altitude pulmonary edema cases were taken X-ray, and oxygen saturation detection. Results: All the 35 cases showed pulmonary edema with different degrees, including 16 cases of localized type, 6 cases of interstitial type, 7 cases of diffuse type and 6 cases of central type. X-ray pulmonary edema was closely related to oxygen saturation. Pulmonary edema was diffuse and central in 12 cases of SaO_2 <50%, and limited and interstitial changes in 23 cases of SaO_2 <73%, of which 16 example. The relationship between the severity of hypoxia and X-ray manifestations is also closely related to the pathological changes, and also reflects the degree and stage of the development of the lesion. Conclusion: Emphasis on the performance of X-ray findings and timely diagnosis of clinical treatment has obvious significance.
