  • Image not available. Four steps to developing a successful nutrition plan include definition of nutrition goals, determination of nutrition requirements, determination of appropriate route of delivery of nutrients, and subsequent monitoring of the nutrition regimen to evaluate suitability of the regimen as a patient's clinical condition changes and to minimize or treat complications.
  • Image not available. The appropriate route of nutrition support depends on the functional condition of the patient's gastrointestinal (GI) tract, risk of aspiration, expected duration of nutrition therapy, and clinical condition.
  • Image not available. Identifying the patient who is most likely to benefit from parenteral nutrition (PN) therapy includes consideration of the patient's age, nutrition status, expected duration of GI dysfunction, and potential risks of initiating therapy.
  • Image not available. PN formulations include intravenous (IV) sources of protein, dextrose, fat, water, electrolytes, vitamins, trace elements, and other additives.
  • Image not available. PN solutions may be appropriately formulated for administration by peripheral or central venous access.
  • Image not available. PN solutions may be infused continuously or intermittently.
  • Image not available. Biochemical and clinical measurements considered necessary for effective monitoring of patients receiving PN include serum chemistries, vital signs, weight, total daily fluid intake and losses, and nutritional intake.
  • Image not available. Non–catheter-related complications of PN therapy are minimized with application of age-appropriate nutrient dosing guidelines, frequent monitoring, and rational adjustments to the PN regimen when metabolic abnormalities occur.
  • Image not available. Expenses associated with PN therapy may be minimized by using PN in appropriate patients, appropriate use of laboratory measurements associated with PN therapy, maximizing efficient purchasing practices for PN solutions and compounding supplies, implementing a standardized process for PN management, and minimizing PN waste.
