How to administer TPN?
Total parenteral nutrition (TPN) is administered through PICC (peripherally inserted central catheter) line, central venous line or port-a-cath.
Assemble the following article;
1. TPN bag
2. TPN infusion set
3. Electronic infusion pump
4. Intravenous access to administer TPN
Steps to Administering TPN
1. Place the TPN bag until reaches room temperature.
2. After the TPN formula reaches the desired room temperature, now add the recommended medication mixture to bag for infusion.
3. Before mixing prescribed medications or multivitamins into the TPN bag, inspect the TPN formula. Use 10ml syringes with needles to draw medications from the vials and inject them into the TPN bag and mixed gently.
4. Insert the IV tubing into TPN solutions.
After that emove air from the IV tube line before attaching it to the patient.
This process is important and prevents the air from going into bloodstream and reduces the risk of air embolism.
5. Now setup the electronic infusion device (EID) to set process of withdrawing the solution from the TPN bag via the pump and into the IV tube line.
6. Put the batteries into the infusion pump and turn it on.
7. An infusion pump controls the rate at which the TPN solution is given.
8. Check infusion rate sheet and TPN infusion settings, attach IV line to pump as instructed and start TPN infusion rate as per physician orders.
9. Clean the injection cap of the catheter in a twisting motion by using an antiseptic wipe. Allow the cap to dry for 10 seconds.
10. Placed the client is in the supine position.
11. Before administering TPN, it is important to flush the lumen of catheter (central line). Flush central line with saline in a push and pause method.
Note: Do not put a lot of pressure during flushing, may feel pain, burning, or swelling.
12. Attach the TPN infusion set the central venous catheter port.
13. Secure the IV line
14. Keep document of all the fluids infusing (IV fluids, IV medications, and TPN solution) to avoid fluid overload.
