本文将经纤支镜或人工气道行防污染样本毛刷、支气管刷检或冲洗吸引、经支气管肺活检的病原学采样技术用于免疫受损而并发肺部感染的患者,并就其诊断价值进行前瞻性研究。40例免疫受损患者41例次发热、肺部浸润拟诊为肺部感染,行42例次病原学采样,删除重复阳性,总阳性诊断率为73.6％,初步表明该采样技术对于免疫受损患者并发肺部感染具有较高的诊断价值。28例次获病原和/或病理诊断:细菌12例13次(绿脓杆菌9次、硝酸盐阴性杆菌1次、金黄色葡萄球菌1次、表皮葡萄球菌2次);曲菌病2例;结核病10例;卡氏肺孢子虫肺炎3例。并就采样技术的安全性和可行性进行讨论和分析。
In this paper, bronchoscopy or artificial airway anti-pollution sample brush, bronchial brushing or flushing to attract, through the bronchial lung biopsy etiology sampling technique for immune compromised patients with pulmonary infection, and its diagnostic value Prospective study. Forty-one immunocompromised patients suffered from fever, pulmonary infiltrates were diagnosed as pulmonary infection, 42 cases of secondary etiological sampling, repeated positive deletion, the total positive diagnostic rate was 73.6%, initially showed that the sampling technique for immune damage Patients with pulmonary infection has a high diagnostic value. 28 cases were pathogen and / or pathological diagnosis: 12 cases of bacteria 13 times (Pseudomonas aeruginosa 9 times, nitrate-negative bacilli once, Staphylococcus aureus twice, Staphylococcus epidermidis twice); Aspergillus disease in 2 cases; 10 cases of tuberculosis; Pneumocystis carinii pneumonia in 3 cases. Discuss and analyze the safety and feasibility of sampling techniques.
