目的：探讨连续血液净化对老年患者肾功能衰竭进行治疗的临床治疗效果。方法随机选取长治市第二人民医院2012年12月至2014年11月收治的90例老年急性肾功能衰竭患者，按照治疗方法的不同将其分为实验组和对照组，其中对照组患者采用普通血液透析方法进行治疗，实验组患者采用连续性血液净化进行治疗，对两组患者治疗前后尿素氮、血清肌酐等观察指标的变化情况及透析并发症的发生情况进行观察记录。结果经治疗两组患者相关指标均明显下降，其中实验组在不同治疗时间其血清尿素氮和肌酐水平均明显低于对照组，差异有统计学意义（P <0.05）。结论采用连续性血液净化治疗老年患者急性肾功能衰竭，能够促进患者肾功能的有效改善，对于保护患者肾功能，提高患者的生存质量具有十分重要的意义，建议在临床上进一步推广。“,”Objective To investigate the clinical effect of continuous blood purification on renal failure in the eld-erly patients. Methods Randomly selected 90 cases of acute renal failure in elderly patients from December 2012 to No-vember 2014,and they were divided into experiment group and control group according to the different treatment methods. The control group were treated by hemodialysis common methods of treatment,and the experiment group were treated by e-ven bloody blood purification treatment,the occurrence of two groups before and after treatment and dialysis complications changes in blood urea nitrogen and serum creatinine were observed and recorded. Results Indicators of the two groups af-ter treated were significantly decreased in the experiment group,and serum urea nitrogen and creatinine levels at different treatment time were significantly lower than those of the control group(P < 0. 05). Conclusions Continuous blood purifi-cation treatment for elderly patients with acute renal failure can contribute to improve renal function,renal function to pro-tect and improve the quality of life of patients,so it is of great significance and worthy of being recommended to further pro-moted in clinical practice.
