What is the difference between TPN and enteral feeding?

Enteral solution is thicker than TPN. It may have the consistency of a milkshake. Total parenteral nutrition bypasses the digestive system entirely and goes directly into the bloodstream, where the nutrients are absorbed. The solution is given through a catheter that has been placed in a vein.

What are the different types of enteral feedings?

Several types of tubes are used for enteral feeding:

• Nasogastric tubes.
• Nasojejunal tube (NJT)
• Jejunostomy tubes (JEJ, PEJ or RIJ tubes)
• Radiologically inserted gastrostomy tube (RIG)
• Percutaneous endoscopic gastrostomy tubes (PEG tube)

When should enteral feeding be considered?

Indications for enteral feeding Artificial nutrition support is needed when oral intake is absent or likely to be absent for a period >5–7 days. Earlier instigation may be needed in malnourished patients (grade A). Support may also be needed in patients with inadequate oral intake over longer periods.

How do you calculate enteral nutrition needs?

On average, enteral formulas deliver between 1.0-2.0 calories/mL of formula. To calculate how much formula is needed, divide the total calorie needs by the amount of calories per mL of formula.

Can you aspirate with a PEG tube?

Aspiration pneumonia is the most common cause of death after PEG placement (30). Data consistently show that feeding tubes (both NG and PEG) actually increase the risk of aspiration pneumonia, perhaps by increasing gastroesophageal reflux or oropharyngeal colonization (31,32).

Can TPN go through G tube?

It can be through a gastrostomy tube (g-tube) in the stomach or a jejunostomy tube (j-tube) in the small intestine.

Is PEG tube the same as TPN?

TPN is not an alternative to PEG feeding in individuals with a functional gastrointestinal tract. However, TPN is occasionally used in Japan for artificial nutrition in older patients with dysphagia regardless of a functional gastrointestinal tract [10]. TPN is more expensive compared to enteral nutrition [11].

What is the maximum length of time an enteral feeding should be held while medications are being administered?

Check infusion hourly and document intake. Feeds should hang for no longer than 4 hours to reduce the risk of bacterial growth.

How do you calculate protein for tube feeding?

Protein needs: 0.8 g./kg of IBW (up to 2 g/kg if stress; 1.2-1.5 g/kg freq. used) or, another way to estimate protein needs: nonprotein calorie to nitrogen ratio. Ratios of 100-150 kcal:1 g N in stressful conditions to promote anabolism and 250-300 kcal:1 g N for normal body maint.
