Pseudomonas Aeruginosa Infection  (铜绿假单胞菌感染)

铜绿假单胞菌肺炎是一种罕见但严重的肺部感染，在重症监护室中可表现为无菌血症的原发性肺炎，或表现为菌血症性肺炎，尤其常见于中性粒细胞减少症患者。该病常累及囊性纤维化患者，导致反复发作的慢性下呼吸道感染。临床表现包括发热、寒战、呼吸困难、发绀、咳嗽咳痰和全身毒性反应。放射学和病理学检查常显示肺泡出血、坏死和空洞形成，这些都会导致严重的发病率和死亡率。

Pseudomonas aeruginosa pneumonia is a rare but severe lung infection that can present as primary pneumonia in intensive care settings without bacteremia or as bacteremic pneumonia, particularly in patients with neutropenia. It frequently affects individuals with cystic fibrosis, leading to recurrent chronic lower respiratory infections. Clinical manifestations include fever, chills, dyspnea, cyanosis, productive cough, and systemic toxicity. Radiological and pathological findings often reveal alveolar hemorrhage, necrosis, and cavity formation, all of which contribute to significant morbidity and mortality.
