细菌能移生于无症状的慢性阻塞性肺疾病(COPD)患者的下呼吸道,这些细菌主要是流感嗜血杆菌,肺炎链球菌和卡他嗜血杆菌,对其在稳定期和加重期COPD下呼吸道所起的作用一直都不十分清楚。为了确定COPD下呼吸道细菌感染的重要性,作者用防护标本刷(PSB)对稳定期和加重期COPD门诊患者进行微生物学取样分析。 方法 A组:40例,为稳定期COPD患者。年龄61.1±9.9岁,FEV_1/FVC 51.7±12.5,胸部X线表现正常或接近正常,具有进行纤维支气管镜检查的临床指征,包括肺结节样病灶和少量咯血。B组:29例,为自
Bacteria can be transplanted in the lower respiratory tract of asymptomatic patients with chronic obstructive pulmonary disease (COPD). These bacteria are mainly Haemophilus influenzae, Streptococcus pneumoniae and Haemophilus catarrhalis, which are stable and exacerbated COPD The role of the respiratory tract has not been very clear. To determine the importance of bacterial infections of lower respiratory tract in COPD, the authors performed microbiological sampling analysis of patients with stable and exacerbated COPD clinics using a protective specimen brush (PSB). Method A group: 40 cases, stable COPD patients. Age 61.1 ± 9.9 years, FEV 1 / FVC 51.7 ± 12.5, chest X-ray findings were normal or near normal, with clinical indications for bronchoscopy, including pulmonary nodular lesions and a small amount of hemoptysis. Group B: 29 cases, since
