摘要
应用慢性呼吸性酸中毒预计代偿公式:ΔHCO_3^-=0.38×ΔPaCO_2±3.78及慢性呼吸性碱中毒预计代偿公式:ΔHCO_3^-=0.49×ΔPaCO_2±1.72结合AG=Na^+-(HCO_3^-+Cl^-)计算,诊断慢性肺心病三重酸碱失衡25例。AG值均>16mmol/L,其中21例(84.0%)>20mmol/L。目前正确判断三重酸碱失衡的关键在于恰当应用AG。AG增高可能是某些混合性代谢性酸中毒和代谢性碱中毒患者酸中毒的唯一证据。只要能排除其他引起AG升高的因素,即可诊断为高AG代谢性酸中毒。结果并提示肾功能不全是形成慢性肺心病高AG代谢性酸中毒的重要因素。
We used the predicting compensatory formula of chronic respiratory acidosis(ΔHCO_3=0.38×ΔPaCO_2±3. 78) and the predicting compensatory formu1a of chronlcrespiratory alkalosis (ΔHCO_3=0.49×ΔPaCO_2±1. 72) in conbination with the cal-culation of the value of anion gap (AC=Na^+ - (HCO_3+Cl)to determine 25 casesof triple acidbase disorders in chronic cor pulmonale. All the value of AG has gonebeyonb 16 mmol/L and, the AG value of 21 cases (84.0%) of them beyond 20mmol/L. Recently, the key to determine triple acid--base disorders is tke correctuse of AG vaIue. The increase of AG may be the onIy evidence of acidosis of somepatients with mixed metabolic acidosis and alkaIosis.If other factors causingthe increase of AG value are excluded,the diagnosis of high AG metabolic acidosiscan be established.The resultsindicate that renal dysfunction is the important fac-tor to induced high AG metabolic acidosis in chronic cor pulmonale.
