侵袭性肺曲霉菌病(invasive pulmonary aspergillosis,IPA)是曲霉菌侵入肺组织引起的深部真菌感染性疾病,主要发生在免疫抑制人群,ICU患者是感染的高危群体。近年来,IPA的发病率呈上升趋势,病死率高达56%~88.1%[1]。本研究拟通过对临床诊断IPA危险因素分析,为IPA的早期诊断、预 Invasive pulmonary aspergillosis (IPA) is a deep fungal infection caused by Aspergillus invades into lung tissue, mainly in immunocompromised patients, and ICU patients are at high risk of infection. In recent years, the incidence of IPA is on the rise with a mortality rate of 56% to 88.1% [1]. This study is intended to analyze the clinical diagnosis of IPA risk factors for the early diagnosis of IPA, pre
