目的探讨急性肾功能衰竭(ARF)住院患者的病因、临床特点以及影响预后的因素。方法对我院1995年1月至2007年12月收治的50例急性肾功能衰竭患者的临床资料进行回顾性分析。结果 50例急性肾功能衰竭中,老年患者38例,占76%,平均年龄(57±18)岁。ARF主要病因为感染、心力衰竭、药物及恶性肿瘤等。年龄、心力衰竭、呼吸衰竭及恶性肿瘤是与预后相关的危险因素以及与ARF患者的死亡相关。接受肾替代治疗患者病死率低于保守患者。结论感染、心力衰竭、药物及恶性肿瘤导致的ARF需要引起关注,住院患者中接受肾替代治疗患者病死率低于保守患者。
Objective To investigate the etiology, clinical characteristics and prognostic factors of hospitalized patients with acute renal failure (ARF). Methods The clinical data of 50 patients with acute renal failure admitted to our hospital from January 1995 to December 2007 were analyzed retrospectively. Results Among the 50 patients with acute renal failure, 38 were elderly patients, accounting for 76% with an average age of (57 ± 18) years. The main causes of ARF infection, heart failure, drugs and malignant tumors. Age, heart failure, respiratory failure and malignancy are risk factors associated with the prognosis and are associated with death from ARF. Patients receiving renal replacement therapy had lower mortality than conservative patients. Conclusions ARF caused by infection, heart failure, drugs and malignant tumors needs attention. The mortality of hospitalized patients receiving renal replacement therapy is lower than that of conservative patients.
