Daily Caloric Delivery via IV Lipids for Dialysis Patients
Energy Requirements for Dialysis Patients
- The American Journal of Kidney Diseases recommends that patients undergoing maintenance hemodialysis or chronic peritoneal dialysis require 35 kcal/kg body weight/day for those under 60 years of age 2, 3
- For patients 60 years or older, the recommended energy intake is 30-35 kcal/kg body weight/day due to reduced physical activity and lean body mass 1, 2
- Metabolic balance studies show that 35 kcal/kg/day induces neutral nitrogen balance and maintains serum albumin and anthropometric indices 2, 4
Scientific Rationale
- Energy expenditure in dialysis patients is similar to that of normal, healthy individuals 1, 3
- Longitudinal and cross-sectional data show that dialysis patients frequently have low energy intake and are underweight, which is associated with increased mortality rates 2, 3
Nutritional Considerations for IV Lipid Administration
- When calculating total energy intake for peritoneal dialysis patients, energy derived from glucose absorbed from peritoneal dialysate should be included 2, 3
- For parenteral nutrition, the recommended protein:fat:glucose caloric ratio should approximate 20:30:50% 5
- Current trends favor increasing the glucose:fat calorie ratio from 50:50 to 60:40 or even 70:30 of non-protein calories to reduce risks of hyperlipidemia and fatty liver 5
Monitoring and Adjustments
- For acutely ill dialysis patients, energy needs may not increase significantly, and 30-35 kcal/kg/day remains appropriate 6
- Weight management in dialysis patients requires careful monitoring by a registered dietitian and physician to ensure fat loss rather than muscle loss 7
