本文分析了COPD病人呼吸衰竭时出现的14例次三重酸硷紊乱,2例为“硷性三重”,12例次为“酸性三重”。“三重”的特点是pH正常或偏酸(“酸性三重”)或偏硷(“硷性三重”);“酸性三重”时PaCO_2上升,“硷性三重”则降低;AG平均为23.4±4.5,△AG>△HCO_3~-,电解质的变化主要为低Cl~-,平均为86.19±7.84。本组病例的三重酸硷紊乱是在原有的慢性呼酸或呼酸并代硷的基础上发生急性发作,严重感染,缺O_2或发展至肺性脑病而发生,病情多属危重,本组病例死亡5例。本文对三重酸硷紊乱的计算及其临床意义作简要讨论。
This article analyzed 14 cases of tertiary acid-base disorders in COPD patients with respiratory failure, 2 with “alkaline triplets,” and 12 with “acid triplets.” “Triple” is characterized by normal or slightly acidic pH (“acid triplet”) or partial base (“alkaline triplet”); PaCO 2 increases with “acid triplet” and “alkaline triplet” decreases with AG average of 23.4 ± 4.5 , △ AG> △ HCO_3 ~ -, the change of electrolyte is mainly low Cl ~ -, with an average of 86.19 ± 7.84. This group of patients with triple acid alkaloids disorder is the original chronic acidosis or acidosis and generation of base on the basis of an acute attack, severe infection, lack of O2 or development to pulmonary encephalopathy occurred, the condition is mostly critically ill, this group of patients 5 died. This article discusses the calculation of triple acid disorders and its clinical significance.
