目的 比较单乙基甘氨酰二甲苯胺（ＭＥＧＸ）肝功能试验和其余肝功能试验在预测外科重危监护（ＩＣＵ）病人发生多器官功能衰竭（ＭＯＦ）及预后方面的作用。方法 １７ 例ＩＣＵ重危监护病人均于术后转入ＩＣＵ病房，术后经３ ｄ 行ＭＥＧＸ肝功能试验及其它肝功能试验。结果 比较ＭＯＦ组和未发生ＭＯＦ组ＭＥＧＸ值有显著差异（Ｐ＜ ０．０５），其余肝功能试验比较未见明显差异（Ｐ＞ ０．０５）。结论 ＭＥＧＸ试验是检测肝功能和预测ＩＣＵ重危病人发生ＭＯＦ及预后的敏感试验。
Objective To compare the role of MEGX and other liver function tests in predicting multiple organ failure (MOF) and prognosis in surgical intensive care unit (ICU) patients. Methods Twenty-seven ICU critically ill patients were transferred to ICU ward after operation. MEGX liver function test and other liver function tests were performed after 3 days. Results There was significant difference in MEGX between MOF and MOF (P <0.05). There was no significant difference in other liver function tests (P> 0.05). Conclusions The MEGX test is a sensitive test for detecting liver function and predicting MOF and prognosis in critically ill patients with ICU.
