目的 :评价X线胸片在新生儿肺出血诊断中的作用。方法 :经病理尸检证实的新生儿肺出血 5 0例。对该 5 0例胸部X线表现进行分析。结果 :病理所见局灶性肺出血及肺水肿在X线胸片表现为肺透光度减低 ;豹斑状或小块状肺出血在X线胸片上表现为片絮状阴影 ;弥漫性肺出血X线表现大片状阴影。新生儿肺出血X线表现分三期 :水肿出血期、出血期和出血晚期。结论 :X线胸片是诊断新生儿肺出血的重要方法 ,能够做出早期诊断并进行临床分期。心影增大是新生儿肺出血的早期X线特征之一。
Objective: To evaluate the role of X-ray in the diagnosis of neonatal pulmonary hemorrhage. Methods: Fifty cases of neonatal pulmonary hemorrhage confirmed by pathological autopsy. The 50 cases of chest X-ray findings were analyzed. Results: The pathological findings of focal pulmonary hemorrhage and pulmonary edema in the X-ray showed pulmonary transparence decreased; leopard spot or small pulmonary hemorrhage in the X-ray showed patchy shadows; diffuse pulmonary hemorrhage X-ray shows large shadows. Neonatal pulmonary hemorrhage X-ray performance in three phases: edema bleeding, bleeding and bleeding late. Conclusion: X-ray is an important method to diagnose neonatal pulmonary hemorrhage. It can make early diagnosis and clinical staging. Increased heart shadow is one of the early X-ray features of neonatal pulmonary hemorrhage.
