Study Notes
Parenteral Nutrition Overview
- Parenteral nutrition provides nutrients intravenously, bypassing the gastrointestinal (GI) tract.
- It is vital for patients unable to intake food due to digestive tract dysfunction.
- Mixture includes proteins, sugars, fats, vitamins, minerals, and other essential nutrients.
Types of Parenteral Nutrition
- Total Parenteral Nutrition (TPN): Supplies all daily nutritional needs.
- Partial Parenteral Nutrition (PPN): Supplements some daily needs, often used alongside oral intake.
Indications for Parenteral Nutrition
- Indicated for compromised nutritional status when oral/enteral feeding is inadequate or impossible.
- Common conditions warranting use include:
- Burns or polytrauma.
- Fistulas making oral feeding undesirable.
- Short bowel syndrome or severe malabsorption issues.
- Intestinal obstruction or pseudo obstruction.
Patient Conditions Requiring Parenteral Nutrition
- Intestinal Obstruction or Ileus: Blockage in the intestine.
- Inadequate Digestive Capacity: Inability to effectively digest food.
- Uncontrollable Vomiting: Can be life-threatening, especially for diabetic patients.
- Surgical Interventions: Patients may have had parts of the digestive system removed, necessitating alternative nutrition methods.
Supplementary Role of Parenteral Nutrition
- Used as a supplement to enteral feeding when sufficient nutrition cannot be achieved through the enteral route alone.
- Essential for critically ill patients needing specialized nutritional support.
Definition of PEN
- PEN stands for Parenteral and Enteral Nutrition, indicating a combination of both methods for patient care.
Liquid Form
- Both parenteral and enteral nutrition are administered as liquids, facilitating easier absorption into the bloodstream.
