尘肺是由于在职业活动中长期吸入生产性粉尘(灰尘),并在肺内潴留而引起的以肺组织弥漫性纤维化(瘢痕)为主的全身性疾病。由于尘肺病并发呼吸道感染的发病率很高,且临床表现较重,如果不积极治疗,迁延不愈,易引起明显的缺氧,加速肺气肿、肺源性心脏病等并发症的发生。临床常用的治疗尘肺病并发呼吸系统感染的方法是抗生素静脉滴注,但容易引起抗生素耐药性及人体菌群失调。针对这一问题,2009-04—2012
Pneumoconiosis is a systemic disease characterized mainly by diffuse pulmonary fibrosis (scarring) caused by long-term inhalation of productive dust (dust) in occupational activities and retention in the lungs. Due to the high incidence of pneumoconiosis complicated with respiratory tract infection and severe clinical manifestations, if you do not actively treat and delay unhealed, it will cause obvious hypoxia and accelerate the occurrence of complications such as emphysema and pulmonary heart disease. Commonly used in clinical treatment of pneumoconiosis complicated by respiratory infections is intravenous antibiotics, but easily lead to antibiotic resistance and human flora.
