肺性脑病(下称肺腑)是肺心病的主要并发症,也是肺心病患者死亡的主要原因;而肺脑的发生、发展又与呼吸道感染密切相关,因此,要降低肺腑的病死率,使处于肺脑缓解期的病人病缓延年,减少发作,其重要环节之一是有效地防治呼吸道感染。呼吸道感染的易患因素一、肺脑病人病期长,年龄大(50岁以上者达80%),心肺功能差,机体抵抗力薄弱,肺净化系统衰退,溶菌酶和粘多糖分泌减少,上皮易受损伤。
Pulmonary encephalopathy (hereinafter referred to as the heart) is the main complication of pulmonary heart disease is also the main cause of death in patients with cor pulmonale; and the occurrence and development of pulmonary brain and respiratory tract infections are closely related, therefore, to reduce the mortality of the heart, Patients with pulmonary remission of patients with slow delay, reduce seizures, one of the important aspects of effective prevention and treatment of respiratory infections. Risk factors for respiratory infections First, patients with long duration of pulmonary disease, older (50 years of age over 80%), poor cardiopulmonary function, the body weak resistance, lung purification system decline, reduced lysozyme and mucopolysaccharide secretion, epithelium Vulnerable.
