目的探讨老年重症急性肾衰竭(ARF)致死预后的相关影响因素。方法对该院近三年收治的老年重症ARF(SARF)的28 d观察期患者162例的临床资料进行分析,并依据预后生存状态,分为死亡组和生存组。结果本研究患者死亡率高达58.02%,在两组临床资料的比较中发现,死亡组与生存组在血肌酐(Scr)、血尿素氮(BUN)、衰竭器官数目、首次接受连续性血液净化(CBP)治疗的时间、伴有基础疾病比例、生前接受3 h以上手术治疗的比例、DIC患者比例均存在明显差异。经多因素回归分析,衰竭器官数和首次接受CBP治疗的时间作为老年SARF预后的相关危险因素。结论通过对老年SARF临床特点资料的分析,寻找其比较全面因素对预后影响因素进行全面分析预防。
Objective To investigate the related factors of lethal prognosis in elderly patients with severe acute renal failure (ARF). Methods Clinical data of 162 cases of severe ARF (SARF) in observation group of 28 days treated in the past three years in this hospital were analyzed. According to the prognosis, the patients were divided into death group and survival group. Results The mortality of this study was 58.02%. Comparing the clinical data of two groups, we found that there was no significant difference in the serum creatinine (Scr), blood urea nitrogen (BUN), the number of failing organs and the first consecutive blood purification CBP) treatment time, with the proportion of underlying diseases, the proportion of patients receiving surgery more than 3 h before surgery, DIC patients there are significant differences. Multivariate regression analysis, the number of failing organs and the time of the first CBP treatment were used as risk factors for the prognosis of elderly SARF. Conclusion Through the analysis of the clinical features of elderly SARF data to find its more comprehensive factors to predict the prognosis of a comprehensive analysis of prevention.
