呼吸衰竭引起脑功能不全综合征,称为肺源性脑病。它是慢性阻塞性肺部疾病的一个严重并发症。国内外报道,病死率均在30～45.6％,其发病据Posner报告:患者意识障碍与脑脊液pH明显降低呈正相关,而和血pH值不相关,故脑脊液的PaCO_2短时间内剧升可做为肺脑病的早期表现。本文肺脑病的临床表现、分型、诊断除根据1980年全国肺心病会议修订标准外,还参考山东陶仲为教授提出的五条标准:①Ⅱ型呼衰基础上发生严重缺O_2和CO_2潴留。②PaO_2降低导致缺氧综合征(多脏器损害)。③PaCO_2
Respiratory failure causes brain dysfunction syndrome, known as pulmonary encephalopathy. It is a serious complication of chronic obstructive pulmonary disease. Domestic and foreign reports, the mortality rate were 30 ~ 45.6%, its incidence According to Posner report: patients with disturbance of consciousness and cerebrospinal fluid pH was significantly decreased, but not correlated with the blood pH, so cerebrospinal fluid PaCO_2 rapid increase can be done as Early signs of pulmonary encephalopathy. In this paper, the clinical manifestations, classification, diagnosis of pulmonary encephalopathy in addition to the 1980 National Conference on Cor Pulmonary revised standards, but also with reference to Professor Tao Zhongwei Shandong five criteria: ① type Ⅱ respiratory failure on the basis of serious lack of O2 and CO2 retention. ②PaO_2 lead to hypoxia syndrome (multiple organ damage). ③ PaCO_2
