    Area of Science:

    • Clinical Nutrition
    • Metabolic Support
    • Intravenous Therapy

    Background:

    • Parenteral nutrition (PN) therapy emerged 35-40 years ago with intravenous amino acid administration.
    • Significant advancements have focused on providing adequate energy via intravenous routes.
    • Two primary PN systems exist: lipid-carbohydrate and glucose-based.

    Observation:

    • The lipid-carbohydrate system mirrors normal food composition and can be delivered peripherally or centrally.
    • The glucose system requires central venous catheter administration.
    • Despite ongoing challenges, current PN knowledge and techniques are highly advanced.

    Findings:

    • Parenteral nutrition effectively maintains nutritional status in patients with oral or enteral intake limitations.

  • This therapy prevents starvation and its associated complications.
  • Both lipid-carbohydrate and glucose systems offer viable options for intravenous feeding.

    • Implications:

    • Parenteral nutrition is a critical intervention for managing complex nutritional needs.
    • Further research is needed to refine PN protocols and address remaining challenges.
    • Improved patient outcomes are achievable through optimized intravenous nutritional support.
