老年重症医院获得性肺炎并发弥漫性肺泡出血综合征15例临床分析

Analysis of clinical features for 15 cases of severe hospital acquired pneumonia in elderly patients complicated with diffuse alveolar hemorrhage syndrome

医院获得性肺炎（hospital acquired pneumonia,HAP）是ICU中最常见的院内感染,重症HAP多并发呼吸衰竭、休克和多器官功能衰竭等,其发病率及病死率在院内感染中均居首位。弥漫性肺泡出血综合征（diffuse alveolar hemorrhage syndromes,DAHS）是以咯血、呼吸困难、缺铁性贫血和X线胸片呈弥漫性肺泡浸润为特征的临床综合征，凡能引起广泛的肺泡毛细血管损伤，导致肺泡腔内出血的任何病因，均可在其病变过程中发生[1]。
