在非透析综合疗法中膳食治疗的原则,应是在限制低蛋白质摄入量的基础上设法提高必需氨基酸的摄入水平,以纠正体内氨基酸代谢紊乱。根据此原则我们为慢性肾功能衰竭患者制备了低蛋白麦淀粉膳食(蛋白质限制在20～40g/24hr,总热量2000～3000kcal/24hr),麦淀粉含蛋白质量甚低(0.4—0.6g％),故以其代替大米,面粉做为主食,既可减少植物蛋白质的进量,又可在低蛋白限量范围内适当增加含必需氨基酸丰富的食品,如蛋,奶、瘦肉等;并使优质蛋白质占膳食中总蛋白质量的50～70％。本组30例病人经治疗1—2个月后,除6例(2例无效,4例因故未坚持治疗)外,病人氮质血症均有减轻,临床症状得到改善,营养状况有所改进,延长了生命,根据6例氮平衡实验结果,提示慢性肾衰病人(Ccr5—10ml/min)的饮食在充足热量摄入的基础上,蛋白质摄入量至少0.5g/kg/24hr,(其中优质蛋白占50—70％),才可达到氮的平衡。
The principle of dietary therapy in non-dialysis combined therapies should be to try to increase the intake of essential amino acids on the basis of limiting low protein intake to correct for the disorder of amino acid metabolism in the body. According to this principle, we prepared low protein wheat starch diet (protein limit 20 ~ 40g / 24hr, total calorie 2000 ~ 3000kcal / 24hr), cereal protein content is very low (0.4-0.6g%) for chronic renal failure patients, Therefore, instead of using rice and flour as the staple food, the amount of plant protein can be reduced, and foods rich in essential amino acids, such as eggs, milk and lean meat, can be appropriately added within the low protein limit, Proteins make up 50-70% of the total protein in the diet. The group of 30 patients after 1-2 months of treatment, in addition to 6 cases (2 cases of ineffective, 4 cases were not insisted for some reason), patients with azotemia were relieved, clinical symptoms improved, nutritional status of some Improve and prolong life. According to the results of six nitrogen balance experiments, it is suggested that the intake of protein should be at least 0.5g / kg / 24hr, and the diet of Ccr5-10ml / min should be at least 0.5g / kg / Which accounted for 50-70% of high-quality protein), can achieve the balance of nitrogen.
