本文报告２６例急性呼吸裹竭患儿血清、脑脊液五项酶活性。结果表明急性呼吸衰竭血清五项酶活性（ＡＳＴ、ＬＤＨ、ＣＫ、ＧＧＴ、ＨＢＤ）明显高于非呼吸衰竭组及正常对照组，有极显著性差异（Ｐ＜０．０１）。未组病例除呼裹外均并发心衰、脑水肿，发生率与血清中ＡＳＴ、ＨＢＤ、ＣＫ、ＬＤＨ、ＧＧＴ酶活性升不相平行。存活病例血清酶活性较正常对照升高２～４倍之间，死亡酶活性较正常升高４～６倍之间，死亡病例酶活性义较存活病例为高，说明呼衰存活病例，心脑等脏器细胞受损较轻，而死亡病例细胞受损严重。故动态监测血清有关酶活性的变化，可作为细胞受损程度的指标，有利于临床观察疗效和判断预后。
This article reports 26 cases of children with acute respiratory failure serum, cerebrospinal fluid activity of five enzymes. The results showed that the five enzyme activities (AST, LDH, CK, GGT, HBD) of acute respiratory failure were significantly higher than those of non-respiratory failure group and normal control group (P <0.01). The incidence of heart failure, brain edema and incidence of AST, HBD, CK, LDH and GGT in serum were not in parallel. Survival patients with serum enzyme activity increased by 2 to 4 times higher than the normal control, the death of the enzyme activity increased by 4-6 times more than normal, the death of patients with enzyme activity than the surviving cases were higher, indicating respiratory failure cases, heart and brain Other organ cells damaged less severe, and the death of patients with severe cell damage. Therefore, dynamic monitoring of serum-related changes in enzyme activity can be used as an indicator of cell damage, is conducive to clinical observation of efficacy and prognosis.
