为降低急性肾功能衰竭（ＡＲＦ）的病死率，对６５例ＡＲＦ患者临床资料中可能与预后特别是转归为死亡的相关因素列项分组，并作统计学处理。结果，高危因素中高分解代谢状态、严重感染、少尿时间≥２周、多脏器衰竭、未及时血液透析及老年患者的死亡率，与其相应的对照组有显著差异。积极预防和处理这些高危因素，可降低病死率。 In order to reduce the mortality of acute renal failure (ARF), the clinical data of 65 patients with ARF may be grouped into the following items according to the prognosis, especially those attributable to death. As a result, there was a significant difference in high-risk metabolic status, severe infection, oliguria time> 2 weeks, multiple organ failure, failure to hemodialysis, and mortality in elderly patients. Active prevention and treatment of these high-risk factors can reduce mortality.
