Total Parental Nutrition (TPN)
Parenteral Parental Nutrition (PPN)
If your family member has a medical condition that prevents them from absorbing nutrition through their GI tract, they may need to receive nutrition through an IV. If that is the case, they may choose to start with an IV line inserted outside the body (peripherally), and they would receive Peripheral Parenteral Nutrition (PPN) for a short term need. PPN provides all the calories someone needs through an IV administration route. However, it’s very harmful to the veins. Most patients’ can not tolerate the high percentage of necessary dextrose or the osmolarity (thickness) required for very long. The veins are just too small to handle it.
Total Parental Nutrition
Therefore, due to the number of particles in total nutrition, which makes it thick and hard on the veins, Total parental nutrition (TPN) usually is administered through a large blood vessel like a subclavian vein in the neck or the superior vena cava. TPN is six times thicker than blood! Here’s why. It contains proteins as amino acids, carbohydrates, electrolytes, vitamins, and trace minerals. A lipid emulsion provides fat. Dextrose 15% -25% in water is the liquid base component. It may be necessary to add insulin to help the body with absorption.
Sterile Technique Strictly Required
Due to the high sugar and protein content, infection is a significant risk with TPN administration. Therefore, following a strict sterile technique is essential at all times. Procedures below review all precautions and procedures for managing central lines in general and TPN in specifics.
Total Parental Nutrition (TPN)
Total Parental Nutrition (TPN) is a way to receive all of your nutrition by IV at home.
TPN is getting all your nutrition by IV. The IVs are delivered to your home from a Pharmacy. When working with TPN, you must always have a clean work area and hands to prevent introducing germs into the IV line that goes directly toward the heart and other major organs of the body.
Key Points to Remember
- Handwashing is the MOST important part of the process for preventing infection. Don’t skip on that step. Scrub with soap and water while you hum Happy Birthday
- Use paper towels to cover work surfaces after you wash them with soap and water to create a second barrier of protection against germs.
- Keep your IVs in the refrigerator until ready for use. However, don’t give them while they are still cold.
- IV’s should be at room temperature when you infuse them. Take them out at least 30 minutes in advance so they can warm up. DO NOT put them in the microwave or run them under hot water to warm them up.
