本文报告了38例(次)肺性脑病(以下简称肺脑)症状、预后与血气、酸碱失衡之关系进行了分析。分析结果血气变化越大,临床症状越重,预后亦越差。昏迷患者中pH≤7.30者占100％,PaCO_2(动脉血二氧化碳分压)≥70mmHg者占92.30％,PaO_2(动脉血氧分压)≤55mmHg者占92.30％。昏迷患者病死率69.23％。本文肺脑酸碱失衡类型均属酸中毒,其中呼吸性酸中毒(以下简称呼酸)病死率为28.12％,呼吸性酸中毒并代谢性酸中毒(以下简称呼酸并代酸)病死率为33.33％,提示混合性酸中毒的预后差。
This article reports the relationship between the symptoms and prognosis of 38 patients with pulmonary encephalopathy (hereinafter referred to as pulmonary encephalopathy) and blood gas, acid-base imbalance. Results of the analysis of the greater changes in blood gas, the more severe clinical symptoms, the prognosis is also worse. Coma patients accounted for 100% of pH ≤ 7.30, PaCO_2 (arterial carbon dioxide partial pressure) ≥ 70mmHg who accounted for 92.30%, PaO_2 (arterial partial pressure of oxygen) ≤ 55mmHg accounted for 92.30%. Coma patients mortality was 69.23%. In this paper, all types of pulmonary acid-base disorders are acidosis, respiratory acidosis (hereinafter referred to as acid) mortality was 28.12%, respiratory acidosis and metabolic acidosis (hereinafter referred to as acid and acid) mortality was 33.33%, suggesting that mixed acidosis, the prognosis is poor.
