Well, first of all i would not just "wing-it". Without an adequate knowledge base of care of this Central line, you put yourself and your patient at risk. Whenever you get a pt in with a treatment, or therapy, or in this case, and IV catheter that you are unfamilar with, ask for your Nursing supervisor to come and inservice you prior to your acceptance of this pt as yours.
So, your post was written yesterday... What have you found out?
There are Four types of Central Lines: PICC's, Non-tunnelled. Tunnelled, and Ports.
What does your patient have?
Central lines are very complex. You have to worry about infections, accessing, which lines you can take blood from, which lines you can put certain medications in, keeping the lines patent (were they in use or heparin locked?), what to do and what it means if you are pushing a medication and your patient suddenly goes into rigors (they shock easily from infection as the line leads straight to the heart)... it's pretty complex.
