本文对12例肺心病呼酸型三重酸碱失衡的患者进行研究,结果提示当疑诊有呼酸合并代酸时,血乳酸含量是一项重要指标,通常应高于5mmol/L,当呼酸合并代酸并疑诊有代碱时应测定血浆“潜在”HCO-_3含量,通常大于AB预计代偿值或高于45mmol/L,当呼酸合并代碱并疑诊有代酸时,除血浆AG值应大于20mmol/L才有诊断代酸的价值外,强调测定血乳酸含量。此外AG值在17mmol/L～20mmol/L范围时,不能完全除外有无代酸,应结合血乳酸含量综合诊断。
In this paper, 12 cases of pulmonary heart disease, acid-base triple acid-base imbalance patients were studied, the results suggest that when there is suspicion of acidosis combined with acid, the blood lactate content is an important indicator, usually higher than 5mmol / L, when call Acid combined with acid and suspected generation of alkali should be measured plasma “potential” HCO-_3 content, usually greater than AB is expected to be compensated or higher than 45mmol / L, when Huacao combined with alkali and suspected of acid, In addition to the plasma AG value should be greater than 20mmol / L have the value of the diagnosis of acid, emphasizing the determination of blood lactate content. In addition AG value in the range of 17mmol / L ~ 20mmol / L, can not be completely except with or without acid, blood lactic acid content should be integrated diagnosis.
