肺癌患者医院获得性肺炎的病原菌和临床特点

Clinical Analysis on Nosocomial Pneumonia in Patients with Lung Cancer

目的 探讨肺癌患者医院获得性肺炎的病原菌和临床特点。方法 回顾性分析医院获得性肺炎 12 6例患者的病例资料。结果 患者的临床表现不典型 ,痰培养分离出 10 2株病原菌 ,其中革兰氏阴性菌占 5 4.9% ,革兰氏阳性菌占 3 0 .4% ,真菌占14 .7% ,耐药情况较严重。结论 老年和机体免疫抑制是接受化疗或放疗的肺癌患者易发生医院获得性肺炎的主要因素 ,对医院获得性肺炎患者应及时诊断 ,并根据细菌药敏结果选用抗生素。

Objective To determine the clinical features and pathogens of nosocomial pneumonia in patients with lung cancer.Methods The data of 126 patients were retrospectively analyzed.Results The clinical manifestations were atypical.102 strains of bacteria were isolated from specimens,among them Gram negative bacilli accounted for 54.9% Gram positive cocci 30.4%,fungi 14.7%.Some bacteria showed multidrug resistance.Conclusion Elderly and immunosuppressive patients with lung cancer are in high risk of nosocomial pneumonia.Early diagnosis should be made.Antibiotic choices should be dependent on the result of drug susceptibility test.
