老年人慢性阻塞性肺病的临床特点分析

目的探讨不同疾病来源的老年人慢性阻塞性肺病（COPD）的临床特点。方法用回顾性调查的方法对206例老年COPD患者进行分析。结果206例老年COPD患者中，122例由慢性支气管炎发展而来，其中31例在COPD的发展过程中合并哮喘，84例由哮喘发展而来。由哮喘发展而来的COPD和COPD合并哮喘的患者其PaCO2平均值较高、容易发生Ⅱ型呼吸衰竭、肺性脑病和气胸，并且合并真菌感染和发生死亡的危险也较大。结论由哮喘而来的COPD和COPD合并哮喘的老年患者，其病情相对较重，并发症多，预后较差。

Clinical features of chronic obstructive pulmonary disease in the elderly:analysis of 206 cases

Objective To observe clinical features of chronic obstructive pulmonary disease(COPD) in the elderly. Methods A total of 206 patients with COPD were retrospectively analyzed. Results Of these COPD patients,122 were developed from chronic bronchitis and 31 were complicated with asthma in the course of development of COPD. Eighty-four COPD patients were developed from asthma. COPD patients developed from asthma or complicated with asthma had higher value of PaCO2 and were apt to develop respiratory failure,pulmonary encephalopathy and pneumothorax.They also had higher risk of fungal infection and death. Conclusion Aged COPD patients developed from asthma or complicated with asthma have severe disease condition,multiple complications and poor prognosis.
