What do you mean by TPN Slideshare?

Central Parenteral Nutrition: often called Total Parenteral Nutrition (TPN); delivered into a central vein – Peripheral Parenteral Nutrition (PPN): delivered into a smaller or peripheral vein A.S.P.E.N. Nutrition Support Practice Manual, 2nd edition, 2005, p.

What are the clinical indications for parenteral nutrition?

Indications for total parenteral nutrition

• Inadequate absorption resulting from short bowel syndrome.
• Gastrointestinal fistula.
• Bowel obstruction.
• Prolonged bowel rest.
• Severe malnutrition, significant weight loss and/or hypoproteinaemia when enteral therapy is not possible.

Who needs parenteral nutrition?

Patients may need PN for any variety of diseases or conditions that impair food intake, nutrient digestion or absorption. Some diseases and conditions where PN is indicated include but are not limited to short bowel syndrome, GI fistulas, bowel obstruction, critically ill patients, and severe acute pancreatitis.

Is parenteral nutrition high risk?

Parenteral nutrition is considered a high-risk nutrition therapy, as there are many potential complications that may arise when parenteral nutrition is used.

What are indications for parenteral nutrition?

Why is TPN bad?

Unfortunately, it can cause potentially fatal complications. TPN infusion results in impairment of gut mucosal integrity, enhanced inflammation, increased cytokine expression and trans-mucosal bacterial permeation.

Why is total parenteral nutrition used?

Parenteral nutrition, often called total parenteral nutrition, is the medical term for infusing a specialized form of food through a vein (intravenously). The goal of the treatment is to correct or prevent malnutrition.

How do you calculate total parenteral nutrition?

An Example of Calculating Macronutrients for Parenteral Nutrition

1. Proteins: 1.5-2 g/kg (based on wounds) 1.5*(50 kg) – 2*(50 kg) = 75 – 100 g protein/day.
2. Fats: 250 mL bag of lipids/day * 2 kcal/mL = 500 kcal/day from fat.
3. Carbohydrates: 1500 kcal/day – kcal protein – kcal fats = kcal of dextrose needed.

When to use parenteral nutrition?

Parenteral nutrition is used to prevent malnutrition in patients who are unable to obtain adequate nutrients by oral or enteral routes. The Society of Critical Care Medicine (SCCM) and American Society for Parenteral and Enteral Nutrition recommends waiting until hospital day number seven.

What is the difference between enteral and parenteral feeding?

Enteral vs Parenteral. • Enteral feeding involves delivering liquid foods through a catheter inserted directly into the gastrointestinal tract, whereas parenteral feeding involves providing nutrients directly into the blood stream. • In the low risk situations, enteral feeding is more preferred than parenteral feeding.

What is parenteral nutrition?

Parenteral nutrition. Parenteral nutrition (PN) is the feeding of specialist nutritional products to a person intravenously, bypassing the usual process of eating and digestion.
