摘要
为探讨慢性肺源性心脏病急性期合并肺性脑病时血气变化情况，将２４例肺性脑病患者和７４例Ⅱ型呼吸衰竭患者作对比研究。结果：肺脑组ＰａＣＯ２升高、ｐＨ降低较呼衰组更明显（Ｐ＜０．０１），肺脑组ＰａＯ２比呼衰组低（Ｐ＜０．０５）；肺脑组以呼酸合并代酸最常见。提示：ｐＨ值与肺性脑病呈负相关（γ＝－０．６６５），ＰａＯ２与肺性脑病呈正相关（γ＝０．７５１）。
Objective To investigate the changes in arterial blood gases in the acute stage of chronic cor pulmonale complicated with pulmonary encephalopath.Methods:A control study was made in 24 of such patients and 74 with respiratory insufficiency but no encephalophthy.Result:Blood pH Levels decreased in group with pulmonary encephalopath,meanwhile increase of PaCO2 and decrease of PaO2 in group with pulmonary encephalopath were significate compared with group without pulmonary encephalopath(p<0.01￣0.05).There is a high risk of pulmonary encephalopath when respiratory acidosis combined with metabolic acidosis,and solitery respiratory acidosis combined with metabolic acidosis,and solitery respilatory acidosis just follows it.Conclusion:There is a negative relation between blood pH values and pulmonary encephalopathl(γ=-0.655),but a positive relation between PaCO2 and pulmunary encephalopath(γ=0.751).
