Inadequate dialysis accounts for the high mortality in patients with end stage renal disease (ESRD). In Nepal, due to various factors including financial and logistic limitations, hemodialysis is mostly performed twice-a-week. This study was undertaken to look at adequacy of dialysis in patients undergoing maintenance hemodialysis in Nepal where the patients profile, in terms of diet, body muscle mass, nutritional status etc are different from western world.
In this cross sectional observational study, 40 patients on maintenance hemodialysis in the dialysis unit were evaluated and enrolled if patients were regularly undergoing twice-a-week hemodialysis in preceding 6 months with each session of dialysis prescription consisting of 4 hours (240 minutes). Patients were excluded if they were admitted in the hospital for some acute problems or had received acute hemodialysis in preceding 6 months. Only 14 patients fulfilled the inclusion criteria. Hemodialysis adequacy was measured using well established urea kinetic modeling.
The mean age of the patients was 49 +/- 24 years. Mean predialysis urea and post dialysis urea were 163.7 +/- 60.05 mg/dL, and 73.7 mg/dL +/- 30.55 respectively. Mean URR was 65.3%. Mean Kt/v as assessed by Jindals equation was 0.99.
Our study showed that twice-a-week of maintenance hemodialysis did not achieve recommended adequacy of hemodialysis in our patients.
透析不充分是终末期肾病(ESRD)患者高死亡率的原因。在尼泊尔,由于包括经济和后勤限制等各种因素,血液透析大多每周进行两次。本研究旨在探讨尼泊尔接受维持性血液透析患者的透析充分性,这些患者在饮食、身体肌肉质量、营养状况等方面与西方世界不同。
在这项横断面观察性研究中,对透析单元中40例接受维持性血液透析的患者进行评估,若患者在过去6个月内定期每周进行两次血液透析,且每次透析处方时长为4小时(240分钟),则将其纳入研究。若患者因某些急性问题住院或在过去6个月内接受过急性血液透析,则将其排除。仅有14例患者符合纳入标准。采用成熟的尿素动力学模型测量血液透析充分性。
患者的平均年龄为49±24岁。透析前尿素平均水平和透析后尿素平均水平分别为163.7±60.05mg/dL和73.7mg/dL±30.55。平均尿素清除率(URR)为65.3%。根据金达尔方程评估的平均Kt/v为0.99。
我们的研究表明,每周两次的维持性血液透析未达到我们患者推荐的血液透析充分性。
