肺部机会性感染在艾滋病(AIDS)病人中非常常见,是发病和死亡的重要原因。但其病因复杂,涉及细菌、分枝杆菌、真菌、病毒和寄生虫等多种微生物,缺乏特异性的临床及影像学表现,诊断困难,往往需要使用侵入性诊断技术,因此纤维支气管镜在这一领域具有重要的应用价值。文章就艾滋病肺部感染支气管镜镜下的特点,支气管肺泡灌洗、纤维支气管镜刷检、经支气管肺活检、经支气管针吸、经支气管镜治疗等,在AIDS肺部感染中的应用进行综述。 Pulmonary opportunistic infections are very common in AIDS patients and are an important cause of morbidity and mortality. However, its etiology is complex and involves many microorganisms such as bacteria, mycobacteria, fungi, viruses and parasites, lack of specific clinical and imaging findings, and often require invasive diagnostic techniques, so Fiberoptic bronchoscopy is here One area has important application value. The article reviews the characteristics of lung infection in AIDS patients with bronchoscopy, bronchoalveolar lavage, fiberoptic bronchoscopy, bronchoscopic lung biopsy, bronchial needle aspiration, bronchoscopy and so on. .
