If a double- or triple-lumen catheter is used, label one lumen for total parenteral nutrition (TPN) use exclusively. Use an IV pump to maintain a constant infusion rate. If the infusion falls behind schedule, the rate can be increased by up to 20% in order to achieve the energy goal.TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath. Patients may be on TPN for many weeks or months until their issues resolve.The blue port is the medial one, opening up somewhere along here… And the white port opens up proximally – here somewhere… If you do use the central line for TPN – which you should! – then that lumen is tied up for good.

What port does TPN go in?
TPN is administered into a vein, generally through a PICC (peripherally inserted central catheter) line, but can also be administered through a central line or port-a-cath. Patients may be on TPN for many weeks or months until their issues resolve.
What color port is TPN?

When would you use a triple lumen catheter?
We describe the use of a triple-lumen catheter inserted through the umbilical vein for infusion of vasoactive substances, fluids, and blood products, and also for withdrawal and exchange transfusion of blood and central venous pressure monitoring.
What is the difference between single lumen and double lumen?
Single-lumen catheters were used for dextrose—amino acids only. Medications or fat emulsions were given either by another central line or peripherally. Double-lumen catheters were used for dextrose—amino acid solutions, compatible medications, and fat emulsions.
What vein is TPN administered?
Central venous catheters for total parenteral nutrition (TPN) have traditionally been inserted via direct cannulation of the subclavian vein, but this technique requires physician participation and is associated with well-described complications.
What is a triple lumen PICC line?
PICC lines are inserted by certified PICC specialists, who use ultrasound and X-ray images to ensure that the line is in the correct spot. PICC lines can have 1-3 lumens, which allow medications to be attached and flow through the line. Additionally, blood draws for lab purposes can also be extracted from the line.
What is a 2 lumen PICC line?
The PICC can be a single or double lumen line. A single lumen PICC has one tubing and one cap on the end. A double lumen PICC has two separate tubings and two caps. A PICC is used to give medications, fluids and IV nutrition. If the PICC is big enough, it can be used to draw blood.

What is a double lumen central line?
A double lumen catheter has 2 lumens while a triple lumen catheter has 3. Multi-lumen catheters allow us to run several different infusion with only one access site (Image 2). Multi-lumen catheters are often inserted through a short central line with a wider inner diameter.
Which lumen is distal on a PICC line?
The distal end of a PICC line catheter should reside in the lower 1/3 of the superior vena cava at the CAJ junction. Outside of the body, the PICC line divides into single, double, or triple lumens. Each lumen has a needleless connector, or a disinfection cap attached to the end.

Is a triple lumen central line tunneled or Nontunneled?
Nontunneled CICCs may be single, double, triple, or quadruple lumen. The different lumens infuse or aspirate fluid through slit-like openings located either on the side or on the distal end of the catheter.
What size is a triple lumen?
Triple-lumen catheter
They are sized using the French scale, with the 7 French size commonly used in adults. These catheters typically have one 16 gauge channel and two 18 gauge channels.
Where is a triple lumen catheter placed?
These catheters may be placed via the subclavian or internal jugular vein, as well as via the femoral vein (2,3). Typically, they stay in place for 7–10 days but may remain in place for longer periods of time.
What is single lumen?
When a catheter has a single hole through the center of it, it is referred to as a single lumen. Single lumens are most commonly used in IV, urological and drainage catheters.
Why does TPN use the large central vein?
Historically, total parenteral nutrition (TPN) has been administered by the central venous route because of the rapid development of thrombophlebitis when TPN solutions are administered into peripheral veins.
What type of IV is used for TPN?
TPN is not compatible with any other type of IV solution or medication and must be administered by itself. TPN must be administered using an EID (IV pump), and requires special IV filter tubing (see Figure 8.10) for the amino acids and lipid emulsion to reduce the risk of particles entering the patient.
Which veins are used for PICC lines?
They can be inserted centrally (centrally inserted venous catheter; CICC) or peripherally (PICC). PICCs are placed through the basilic, brachial, cephalic, or medial cubital vein of the arm. The right basilic vein is the vein of choice due to its larger size and superficial location.
How many lumens does a midline have?
Standard midlines can range from 10 to 20 centimeters in length and can have a single lumen or double lumen. They are typically used for infusion and short-term intravenous therapies.

What does a double lumen PICC look like?
Double lumen PICCs may have a BROWN or PURPLE hub and a WHITE hub. Generally the BROWN or PURPLE lumen is used to take blood samples and for giving blood products. The WHITE lumen is used for medications and IV fluids.
Do you flush both lumens of a PICC line?
Flushing your catheter
Both lumens of your Hickman catheter, and the one lumen in your PICC catheter, need to be flushed once a day with a solution called Heparin, which prevents clotting. You can follow the same steps for either a Hickman or PICC line.
