摘要
20例免疫功能低下患者21次并发发热和肺浸润经纤维支气管镜(纤支镜)行防污染样本毛刷(protected speimen brush,PSB)采样、吸引和(或)经支气管肺活检(transbronchiallung biopsy,TBLB)诊断22例次。删除重复阳性13例次获得特异性病原学诊断:3例4次细菌性肺炎(绿脓杆菌3例,表皮葡萄球菌1例);曲菌病2例;结核病6例;卡氏肺孢子虫肺炎1例。3例最终不能证明感染性病因。感染的病原学诊断率72.2％。表明纤支镜检查是免疫功能低下患者肺部感染有价值的诊断方法。鉴于此类患者临床病情危重,特别就纤支镜检查的可行性及注意事项进行了讨论。
A series of 22 PSB, aspiration samples and/or lung biopsies were obtained via fiberoptic bronchoscopy from 20 immunocompromised patients during 23 episodes of fever and pulmonary infiltration. Excluding overlapping positive diagnoses, the specific infectious etiologies were identified in 18 episodes. Pulmonary infections included: Bacterial pneumonias in 3 cases with 4 episodes (pseudomonas aeruginosa 3, staphylococcus epidermis 1), asp'ergillosis 2, tuberculosis 6, pneumoeystis carinii pneumonia 1. Infectious causes were not finally proved in 8 patients, so that diagnostic accuracy was 72.2% (18/18). The data indicates that sampling and biopsy via fiberoptic bronchoscopy is a valuable diagnostic procedure in immunocompromised patients with pulmonary infections. Owing to the critically ill conditions of those patients, the feasibility and cautions to be taken for fiberopticbronchscopy is particularly discussed.
