How to take care of the catheter after installation: You will feel a slight pain and it will relieve within a few days. It takes about an hour for catheter installation and there is no need to stay in the hospital after that. It may cause some complications such as: blood clotting, haemolysis, infection, neurological effect and catheter clogging. Uses of Triple lumen central venous catheter: For administration of hyperosmolar solutions, measuring CVP, haemodialysis, plasmapheresis, rapid infusion of fluid among other uses, chemotherapy. It has triple lumens, the proximal one for taking blood samples for medical examination and blood administration, the medial lumen for total parenteral nutrition, and the distal lumen for medication. They may be soon.It is a long tube entered from peripheral veins till it reaches the central veins around the heart.

So plan a little - always save a port - maybe one of the medial ones - on a newly placed central line for TPN (even if the patient isn't on it yet. We also use the distal port for giving blood products, simply because it's big: the distal port is a 16-gauge lumen, while the other two are 18's.

We usually hook up the distal port to the transducer for reading CVP's, because the medial and proximal ports can snuggle up to the vessel wall and give weird waveforms. If the patient becomes critical enough, then you can take the TPN down and use the port for something else, but you can't use the port for TPN again - the patient will need a new line. If you use the central line for TPN - which you should! - then that lumen is tied up for good. Make sure that the team has checked: you should never infuse anything through a port that doesn't have a blood return. The medial port is the next one backwards, and the proximal port is the one closest to the skin. So the lumen that opens up at the very tip-end of the catheter - that's the distal port, because it opens the farthest away from the insertion point. In other words, the ports are proximal or distal in relation to the site where the line goes into the patient. The ports are described as proximal, medial and distal - these are the reverse of proximal and distal as regards the patient.
