目的回顾性分析婴幼儿金黄色葡萄球菌性肺炎(简称金葡肺炎)的X线表现与临床特征,探讨两者之间的关系。方法对55例血液、脓液及咽试子培养及凝血酶阳性确诊为金葡肺炎的婴幼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%婴幼儿发病急,伴发热,白细胞升高,50%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24 h内出现肺气囊,50%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。结论婴幼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线表现与临床有不一致性。
Objective To retrospectively analyze the X-ray findings and clinical features of Staphylococcus aureus pneumonia in infants and young children, and to explore the relationship between the two. Methods A total of 55 cases of chest pain and all the clinical data of 55 infants and young children with blood, pus, throat prothrombosis and thrombin positive diagnosed with gingival Pneumonia were retrospectively analyzed and their characteristics were found out. Results 89% infants and young children with acute onset, fever, leukocytosis, 50% cases were combined with omphalitis, osteomyelitis or skin abscess. X-ray showed multiple lung exudation lesions, lung capsule occurred within 24 h in 80% of cases, 50% of cases of pleural invasion, no spherical lesions. After the acute phase, the performance of the chest is still significant and clinically high fever and white blood cells do not have the performance. Conclusions Infants and children with gingival Pseudomonas aeruginosa are mostly of hematogenous origin. The chest radiograph may appear earlier in the lung and may be involved in the pleura. The X-ray manifestations and clinical manifestations are inconsistent.
