                                According to the National Institutes of Health, total parenteral nutrition (TPN) provides complete nutrition intravenously when the digestive system cannot be used. TPN admixtures are complex, sterile formulations containing a precise mixture of macronutrients, micronutrients, electrolytes, and water to meet a patient's specific nutritional needs.
