老年肺癌非手术治疗医院内获得性肺炎的临床特点分析及对策

目的探讨老年肺癌非手术治疗患者医院内获得性肺炎的临床特点及对策。方法对2006年1月至2008年12月住院的275例非手术治疗老年肺癌的医院内获得性肺炎（Hospital-acquired pneumonia,HAP）情况进行回顾性分析。结果本组病例发生院内获得性肺炎165例。以中央型肺癌、鳞癌易发院内获得性肺炎;由革兰阴性菌导致的HAP明显高于革兰阳性菌与真菌;放疗加化疗HAP感染率高于单纯放疗或化疗;随着白细胞下降,感染率明显增高,特别是粒细胞〈1.0×10^9/L者感染率最高。结论根据老年肺癌非手术治疗院内获得性肺炎的临床特点把HAP的预防作为根本措施,一旦出现感染应及时治疗。

The clinical feature and countermeasures of hospital-acquired pneumonia in non-surgical treatment elderly inpatients with lung cancer

Objective To analyze the clinical feature and treatment strategy of Hospital-acquired pneumonia (HAP) in old age patients with lung cancer. Method 275 cases of HAP in non-surgically treated elderly inpatients with lung cancer during January 2006 to December 2008 were included and analyzed retrospectively. Result Among these patients, 165 cases occurred Central-type lung cancer, squamous cell carcinoma were prone to develop HAP; HAP caused by gram-negative bacteria was significantly higher than that caused by gram-positive bacteria and fungi; HAP infection rate in radiotherapy plus chemotherapy group was higher than that in chemotherapy or radiotherapy alone group; Along with the decrease of neutrophilic leukocyte, the infection rate was significantly higher, especially when the neutrophilic leukocyte < 1.0 × 10~9/L. Conclusion According to the clinical feature of HAP in non-surgically treated elderly inpatients with lung cancer, the prevention of HAP should be a fundamental measure, and treatment should be given in time once the infection occurs.
