肺性脑病(以下简称肺脑)是呼吸功能衰竭的严重并发症之一,也是造成死亡的主要原因。它的病死率,1973年以前为32.5～77％(平均为50％)。1977年全国肺心病会议一组资材报告367例住院肺脑患者中死亡147例(病死率为40.1％),又如华北地区报告367例次住院肺脑患者中死亡313例(病死率为49.7％),湖北省报导的109例中死亡47例(病死率为43.1％),均说明病死率很高,因此积极防治肺脑是降低肺心病病死率的重要环节。1980年第三次全国肺心病会
Pulmonary encephalopathy (hereinafter referred to as pulmonary brain) is one of the serious complications of respiratory failure, but also the main cause of death. Its case fatality rate, before 1973, was 32.5 to 77% (an average of 50%). 1977 National Pulmonary Heart Disease Conference a group of materials reported 367 cases of hospitalized pulmonary brain death in 147 cases (mortality rate was 40.1%), another example of North China reported 367 cases of hospitalized lung-brain patients died of 313 cases (mortality was 49.7% ). Of the 109 cases reported in Hubei Province, 47 were fatal (case fatality rate was 43.1%), both of which showed a high case fatality rate. Therefore, active prevention and treatment of pulmonary and cerebrovascular diseases are an important part of reducing the mortality of pulmonary heart disease. The third national pulmonary heart disease in 1980
