They are suitable for longer-term use than peripheral catheters – and can be left in situ for up to 14-21 days.ĬVCs do carry increased risks and special considerations when compared with standard peripheral IV catheters, and as nurses, we need to be aware of these to plan our nursing care effectively.
The administration of hyperosmolar solutions which would not be suitable for peripheral veins, due to an increased risk of phlebitis these solutions include concentrated glucose (>7.5%) solutions and parenteral nutrition solutionĪllowing measurement of central venous pressure (CVP)Ĭollection of multiple blood samples through the sampling port, without performing repeated venipuncture The administration of multiple (incompatible) agents at once through multi-lumen catheters (two or three separate lines, allowing for complete separation of incompatible substances through the same catheter) Why use one?ĬVCs have several benefits and specific indications, including: These are generally large-bore catheters and can be multi-lumen, allowing multiple fluids to be administered simultaneously. What is a central venous catheter?Ĭentral venous catheters (CVCs, or central lines) are catheters placed in such a way that the tip of the catheter sits in the vena cava.
#Triple lumen central line lumen size how to#
In today’s post, we’re talking all about what central venous catheters are, how they are placed, when to use (and when not to use!) them, and how to nurse the CVC patient. These are incredibly fun to place, allow us to administer multiple drugs and fluids easily, and collect samples without the need for repeated venipuncture - what’s not to like? One fantastic example of how we can do more to support our critical medical patients is through placing and maintaining central venous catheters. You will probably find, however, that someone in the hospital has already obtained this information.You folks know that if there’s one thing I’m passionate about, it’s us nurses doing more with our skills. They are usually very accommodating and will supply educational materials to the staff. You merely have to contact the representative who sells them to the hospital. The manufacturers also have a lot of information about the lines that your hospital purchases from them. You might contact your central supply people or the personnel who insert these PICC lines and ask if they have any information about them that they can share with you. It has information about the catheter in it. This booklet is usually placed in the chart at the time of insertion (at least that's where we put it). There is also a booklet that accompanies each PICC insertion kit. Most PICC lines have one lumen that is slightly larger than the other. The minute any infused solution exits the PICC it enters the turbulent blood flow of the superior vena cava and is instantaneously mixed with the incoming blood flow going into the right atrium of the heart and is hemodiluted. The turbulence of the blood in that anatomical area makes the idea of any solutions getting intermingled moot. This can be confirmed by looking at the x-ray report because the placement of the catheter tip should have been confirmed by x-ray. Usually, it is in the superior vena cava of the heart. The answer to the question at hand ultimately lies in where the tip of the PICC line rests. One of the reasons for inserting a dual lumen PICC is for the purpose of infusing two different solutions (including a blood and blood products) through each line at the same time.
