The Changes of Arterial Blood Lactate and Serum Tissue Release Enzymes (LDH,AKP,CK)in the Critical Illeness and Their Correlation / 中国医师杂志

ABSTRACT

Objective To study the changes of arterial blood lactate(ABL) and serum enzymes activities and thier correlation.Method Lactate dehydrogenase(LDH),alkaline phosphatase(AKP) and creatine kinase(CK) in serum were determined in sixty-four critical patients in the intensive care unit(ICU) at admission immediately,following 24h,48h and 72h,respectively.The patients was divided into three groupsfavorable,survival and death groups.Results Before treatment,ABL level was(3.9?2.5,2.9?1.3 and 3.8?2.3)mmol/L in favorable,survival and death groups respectively.Although ABL in favorable and survival groups were decreased gradually to normal level during 24～72h,the death group showed that the decline was very slowly it still persistent elevated in 72h.There was significanct difference between the death group and the favorable and survival groups(P
