血液透析病人的存活率受到病人年龄、血压、相对体重和基本肾疾病的影响,近来发现与血清尿素、肌酐浓度也有密切联系。作者分析了134例血液透析病人,评价了血清尿素/肌酐比值作为透析病人预后指标的临床价值。作者们发现尿素/肌酐比值与病人存活率有显著关系,比值在25.5以下的病人2年存活率是78.4％,而比值在31.3以上的病人是42.1％。病人年龄和舒张压对存活率也有显著影响,而且有协同影响的作用,经年龄和舒张压因素校正后,尿素/肌酐比值和存活率的关系仍存在,证实这一因素对病人存活率有独立的影响。
The survival rate of hemodialysis patients by the patient’s age, blood pressure, relative body weight and basic renal disease, recently found that serum urea and creatinine concentrations are also closely linked. The authors analyzed 134 hemodialysis patients and evaluated the clinical value of serum urea / creatinine ratio as a prognostic indicator of dialysis patients. The authors found a significant association between urea / creatinine ratio and patient survival, with a 2-year survival rate of 78.4% for patients below 25.5 and 42.1% for patients with a ratio above 31.3. The patient’s age and diastolic blood pressure also have a significant effect on the survival rate, and have a synergistic effect. The relationship between the urea / creatinine ratio and the survival rate still exists after being corrected by the age and the diastolic pressure factor, confirming that this factor has an independent effect on the patient survival rate Impact.
