NUTRITIONAL CONTENT TPN requires water (30 to 40 mL/kg/day), energy (30 to 45 kcal/kg/day, depending on

energy expenditure), amino acids (1.0 to 2.0 g/kg/day, depending

on the degree of catabolism), essential fatty acids, vitamins, and minerals 

Normally, 2 L/day of the standard solution is needed Solutions may be modified based on laboratory

results, underlying disorders… Calculate requirements for water (30 to 40

mL/kg/day), energy (30 to 45 kcal/kg/day, depending on energy expenditure), amino acids (1.0 to 2.0 g/kg/day, depending on the degree of catabolism), essential fatty acids, vitamins, and minerals

MONITORINGPlasma glucose should be monitored every 6 h until patients and glucose levels become stable. Fluid intake and output should be monitored continuously. When patients become stable, blood tests can be done much less often.
