本文介绍28例慢性肾功能不全患者,在实行控制饮食和营养后,肾功能改善。方法慢性肾功能不全的饮食,主要是低蛋白,每日摄入20或30g 蛋白质和2,000卡热量,蛋白质的热量占80卡以上。电解质每日平均值:钠2.4g 以下,钾1.0g,钙和磷则大约为普通饮食的1/2～1/3。结果 28例33次中,其中13例次(A 组)有失血、失水、尿路梗阻、心肌梗塞等合并症;20例次(B 组)有饮食不当等。治疗时间:A 组为1.5±0.9个月,B 组为3.1±2.4个月。生化检验(平均值)治疗前后分别为:尿素氮120及45mg/dl;肌酐10及6mg/dl;磷,7及4.2 mg/dl;钙3.8及4.4 mEq/L。上述结果,经统计学处理,有非常显著的差异(P<0.001).作者认为:低蛋白高热量饮食能改善肾功能,其机制可能因为低蛋白饮食同时也是低磷饮食,对慢性肾功能不全所继发的甲状旁腺功能亢进和转移性钙化 This article describes 28 patients with chronic renal failure, after the implementation of diet and nutrition control, renal function improved. Methods Chronic renal insufficiency diet, mainly low protein, daily intake of 20 or 30g protein and 2,000 calories, protein calories accounted for more than 80 cards. Electrolyte daily average: sodium 2.4g the following, potassium 1.0g, calcium and phosphorus is about the general diet 1/2 ~ 1/3. Results Among 28 cases and 33 cases, 13 cases (group A) had complications such as blood loss, dehydration, urinary tract obstruction and myocardial infarction; 20 cases (group B) had improper diet. Treatment time: A group was 1.5 ± 0.9 months, B group was 3.1 ± 2.4 months. Biochemical tests (mean) before and after treatment were: urea nitrogen 120 and 45 mg / dl; creatinine 10 and 6 mg / dl; phosphorus 7 and 4.2 mg / dl; calcium 3.8 and 4.4 mEq / L. The above results, statistically significant difference (P <0.001) .The author believes that: low-protein high-calorie diet can improve renal function, the mechanism may be due to low protein diet is also a low-phosphorus diet, chronic renal insufficiency Secondary hyperparathyroidism and metastatic calcification
