肺心病人临终前酸碱失衡及死亡原因的探讨

A study on acid-base disorders and causes of death in patients with cor pulmonale

本文分析了179例肺心病人临终前动脉血气、血电解质和死亡原因。结果表明:肺心病人在临终前的酸碱失衡是常见的。其中慢性呼吸性酸中毒最常见,其它依次为三重酸碱失衡、慢性呼吸性酸中毒并代谢性酸中毒和慢性呼吸性酸中毒并代谢性碱中毒。慢性呼吸性碱中毒、慢性呼吸性碱中毒并代谢性碱中毒和代谢性酸中毒是少见的。肺心病人死亡的主要原因是并发上消化道出血,其次为直接死于酸碱失衡,特别是三重酸碱失衡。

The results of analysing 179 patients with pulmonary heart disease (PHD) show an acid-base disorder just before death.Acid-base disorder,chronic respiratory acidosis is the most commoa Triple acid-base disorder,chronic respiratory acidosis plus metabolic acidosis and chronic respiratory acidosis plus metabolic alkalosis are in succession.Chronic respiratory alkalosis ( CRA),CRA plus metabolic alkalosis and metabolic acidosis are seldom.The major cause of death in patients with PHD is supper gastrointestinal hemorrhage,the next is acid-base disorder,especially triple acid-base disorders.
