Nitrogen is a fundamental chemical component of amino acids, the molecular building blocks of protein. As such, nitrogen balance may be used as an index of protein metabolism. [1] When more nitrogen is gained than lost by an individual, they are considered to have a positive nitrogen balance and be in a state of overall protein anabolism.
Along with UUN, values for BUN, protein content of diet, enteral or parenteral nutrition, and notable outputs other than urine (gastric residual, fistula output, drainages) are needed to calculate nitrogen balance. Nitrogen Balance = Protein intake/6.25- (UN + 4*) * For average loss via sweat and feces.
Enteral nutrition (administering nutrition using a feeding tube) is started within 24 to 48 hours of admission with feeding targets increased every week. The risk of aspiration (inhalation of fluid or food particles while drinking or eating) can be reduced by elevating the head, using prokinetic agent , and using a chlorhexidine mouthwash.

This diet should also comply with two more requirements: the first is to not consume more than 1 g of protein/kg body weight/ day, [46] as a greater amount could increase the degree of proteinuria and cause a negative nitrogen balance. [18] People are usually recommended lean cuts of meat, fish, and poultry.
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form.
