摘要
目的探讨不同透析方式对老年肾衰病人氮平衡和营养状况的影响。方法对6例腹膜透析（PD）组,7例血液透析（HD）组,8例血液滤过（HF）组患者测定3~7d氮平衡,并进行营养风险筛查（NRS）、营养摄入量调查分析、以及抽血检测相关生化指标。结果PD组、HD组和HF组透析液中氮丢失量存在着较大的差异（P〈0.05）,分别为4.61g、12.03g和10.00g。一周累积氮平衡PD组和HD组病人可维持正氮平衡,而HF组患者存在严重的负氮平衡,同时三组膳食营养素摄入量明显低于正常,并存在不同程度的贫血、低蛋白血症和营养风险。结论实施血液透析老年病人通过透析液丢失大量氮,三组患者尤其是HF组患者营养状况不容乐观,迫切需要对存在营养风险的透析患者开展正确有效的营养支持。
Objective To explore different dialysis modality on the impact of nitrogen balance and nutritional status in elderly patients. Methods Six PD patients group, seven HD patients and eight HF patients were enclosed in this study,Three to seven days of nitrogen halance, nutritional risk sereening（NRS）, diet and nutrients intakes, as well as biochemical parameters were investegated. Results PD, HD and HF Group （P≤0.05）, nitrogen loss was 4.61 g, 12.03g and 10.00g respectively in the dialysate. Weekly cumulative nitrogen halance PD group and HD patients can maintain positive, but HF patients were in severe negative, nilrogen halance, Dietary inlake was signifieantly lower than reennuuendly, and there were different levels of anemia, hypoalbuminemia and nutritional risk. Conclusions Dialysis patients lost a lot of nitrogen through dialysate,The nutritional status in all three groups, espcially HF patients, was not optimistic, and it is urgent to give conict and effective nutritional support to dialysis patients wilh exisled nutrition risk.
