随着广谱抗生素、糖皮质激素和免疫抑制剂的广泛应用,深部真菌感染的发病率日益增加。而肺真菌感染占内脏深部真菌感染的60％以上。老年COPD(慢性阻塞性肺疾病)患者,因年迈、体弱、长期缺氧、反复肺部感染、长期用抗生素、激素等往往成为肺真菌感染的高发人群,且为严重的并发症和导致死亡的重要原因,早期诊断比较困难。本文对本科近年来收治的116例 With the widespread use of broad-spectrum antibiotics, glucocorticoids and immunosuppressive agents, the incidence of deep fungal infections is on the rise. Pulmonary fungal infections account for more than 60% of visceral deep fungal infections. Elderly patients with chronic obstructive pulmonary disease (chronic obstructive pulmonary disease), often due to age, frail, chronic hypoxia, recurrent lung infections, long-term use of antibiotics, hormones, etc. often become a high incidence of pulmonary fungal infection, and for serious complications and lead to death The important reason for early diagnosis is more difficult. This article admitted to the undergraduate in recent 116 cases
