新生儿金黄色葡萄球菌肺炎的X线与临床特征

X-Ray Appearance and Clinical Features of Newborn Staphylococci Aureus Pneumonia

目的 回顾性分析新生儿金黄色葡萄球菌性肺炎 (简称金葡肺炎 )的X线征象与临床特征 ,探讨两者之间的关系。方法 对 110例血、脓及咽试子培养及凝血酶阳性确诊为金葡肺炎的新生儿患者的胸片及全部临床资料 ,进行回顾性分析并找出其特征。结果 89%新生儿发病急 ,伴发热 ,白细胞升高 ,5 0 %病例分别合并有脐炎、骨髓炎或皮肤脓肿等。X线表现为多发双肺渗出病变 ,80 %病例 2 4h内出现肺气囊 ,5 0 %病例胸膜受侵 ,未见球形病灶。急性期过后 ,胸片表现仍然显著而临床可无高热及白细胞增高的表现。结论 新生儿金葡肺炎多为血源性 ,胸片可较早出现肺气囊 ,易累及胸膜 ,X线征象与临床表现有不一致性。

Objective To analyze the X ray appearance,clinical features and their relationship of newborn staphylococci aureus pneumonia. Methods The X ray appearance and their clinical data of 110 newborn staphylococci aureus pneumonia,which were confirmed by pathology,were analyzed. Results Eighty nine percent patients had fever and WBC rising,50 percent had pneumonia,myelitis,skin abscess and so on.The typical X ray appearance was multiple exudative lesions in both lung fields,80 percent cases appear lung air sac within 24h,50 percent cases had pleura invaded,none have globular lesion.And the abnormal appearance of X ray kept longer than clinical syndrome. Conclusion Newbron staphylococci aureus pneumonia has lung air sac in early stage easily involving pleura.X ray appearance is discordance with clinical syndrome.
