目的:探讨危重症患者血清胆碱酯酶(CHE)变化及其临床意义.方法:检测患者血清CHE浓度,并进行急性生理学与慢性健康状况(APACHEⅡ)评分.分析血清CHE浓度变化与APACHEⅡ评分的相关性,同时观察患者肝功能的变化情况.结果:进入ICU时血清CHE下降发生率为85.3%,血清CHE水平与APACHEⅡ评分呈显著负相关.结论:危重症患者血清CHE下降发生率较高,测定血清CHE可作为判断危重症患者病情的一个有意义指标.%Objective: To explore the changes of serun cholinesterase (CHE) and its clinical significance in critical care patients.Methods: Serum cholinesterase (CHE) concentration,acute pathophysiology and chronic health evaluation (APACHE) Ⅱ seores were estimated in patients.To analyze the relationship of serum CHE density variation and APACHE Ⅱ scores.At the same time, to observe the variation of patients' liver function.Results: Serum CHE decreasing occurrence rate was 85.3％ in patients when admitted to ICU.The serum CHE level had eminent negative correlations with APACHE Ⅱ scores.Conclusion: Critical care patients' serum CHE decreasing occurrence rate is comparatively high, so the inspection of serum CHE could be one meaningful index for judging the condition of critical care patients.
