37例免疫受损患者肺部感染的诊断分析

Diagnosis and Analysis of Pulmonary Infection in 37 Immunocompromised Patients

目的对免疫受损并发肺部感染患者的诊断方法、病原学特点进行探讨。方法方便选取2014年2月—2016年2月期间,在该院进行治疗的37例免疫受损并发肺部感染患者,所有患者均给予常规痰检与支气管镜检查,对两种方法的检出率及结果进行对比、分析。结果在免疫受损并发肺部感染患者病原阳性诊断率方面,常规痰检阳性率为37.84%,支气管镜检阳性率为74.29%,后者明显高于前者,差异有统计学意义(P<0.05)。免疫受损患者肺部感染病原学有别于免疫功能正常者,多以院内感染病原菌、真菌、结核、原虫感染为主。结论免疫受损并发肺部感染患者及早行支气管镜检查,病原菌阳性检出率较高,对明确病原学诊断具有重要临床价值。

Objective This paper tries to explore the diagnostic methods and etiological characteristics of patients with immunocompromised pulmonary infection.Methods 37 cases of immune in this hospital from January 2014 to January 2016 were convenient selected selected from the patients with impaired pulmonary infection,all patients were given routine sputum examination and bronchoscopy examination,the detection rate and the results of the two methods were analyzed.Results In the immunocompromised patients with pulmonary infection,the positive rate of sputum examination was 37.84%,the positive rate of bronchoscopy was 74.29%,which was significantly higher than the former(P<0.05).The etiology of pulmonary infection in immunocompromised patients is different from those with normal immune function,and most of them are pathogenic bacteria,fungi,tuberculosis and protozoal infections in nosocomial infection.Conclusion Immunocompromised patients with pulmonary infection and early bronchoscopy,the positive detection rate of pathogens higher,clear pathogenic diagnosis has important clinical value.
