老年人ARF死亡危险因素及影响其肾功能转归的因素

The elderly ARF death risk factors and the factors affecting the outcome of renal function

目的:探讨老年急性肾功能衰竭(ARF)患者死亡的危险因素及影响其肾功能转归的因素。方法:选择我院2010年1月-2012年269例住院ARF患者资料,根据年龄分为老年组(≥60岁)87例,非老年组(<60岁)182例,进行对比分析。结果:老年组与非老年组采用透析治疗的比例分别为52.87%、53.85%,放弃治疗比例分别为19.54%、19.78%;差异无显著性,无统计学意义P>0.05。老年组痊愈21例,痊愈率24.14%,死亡43例,死亡率49.43%,死亡率明显高于非死亡组,两组比较差异具有显著性,有统计学意义P<0.05。主要危险因素为感染、合并严重基础疾病、合并MOF、无尿或少尿,以上因素具有代表性,有统计学意义P<0.05。结论:老年ARF患者死亡率明显高于非老年人,影响患者预后的主要因素为感染、合并严重基础疾病、合并MOF、无尿或少尿。

Objective：To study the elderly patients with acute renal failure（ARF） is a risk factor for death and the factors affecting the outcome of renal function.Methods：Our hospital in January 2010-2012,2012 cases of hospitalized patients with ARF,according to the age is divided into 87 cases of elderly group（60） or higher,and the elderly group（60 years old） of 182 cases were analyzed.Results：The proportion of elderly group and non elderly group adopt the dialysis were 52.87%,53.85%,respectively,to give up treatment rate were 19.54%,19.78% respectively;There was no significant difference,no statistical significance（P〈 0.05）.Elderly group 21 cases cured,recovery rate is 24.14%,43 cases of death,mortality is 49.43%,mortality was significantly higher than the death group,two groups have significant difference comparing,there are statistically significant（P〈 0.05）.Major risk factors for infection,severe basic diseases,the combining MOF,anuria or oliguria,representative,those factors had statistical significance（P0.05）.Conclusion：In elderly patients with ARF mortality was significantly higher than the old,the main factors influencing the prognosis of patients to infection,severe basic diseases,the combining MOF,anuria or oliguria.
