Central Lines


Types of Central Lines: 


  1. Peripherally Inserted Central Catheter – PICC
  • typically used in patients receiving antibiotics for an extended time period
  • inserted in the antecubital fossa
  • central catheter is inserted and threaded through the peripheral catheter
  • distal catheter tip lies in the superior vena cava
  • have positive, negative pressure valves preventing the inflow of air or outflow of blood.

Does not require heparin flushing 

  • flush with NS after each use
  • use 12ml or larger syringe

 2. Port- A- Cath 

  • A catheter connects the port to a vein.
  • Implanted venous access device
  • resembles small pacemaker in size
  • implanted in upper chest
  • tip lies in the superior vena cava
  • Huber needle access only
  • no external devices emerge from skin
  • heparin flushed

 3. Hickman aka Broviac  

  • a central line that is tunneled under the skin so that the exit site is away from where the catheter enters the blood vessel
  • has free-hanging line
  • does not have antireflux valve like PICC

4.Tunneled catheter

  • A vascular access device whose proximal end is tunneled subcutaneously from the insertion site and brought out through the skin at an exit site
  • Passing the catheter under the skin helps keep it in place better, lets you move around easier, and makes it less visible.

 5.Implanted port

  • similar to a tunneled catheter but is left entirely under the skin.
  • Medications are injected through the skin into the catheter.
  • Some implanted ports contain a small reservoir that can be refilled in the same way.
  • After being filled, the reservoir slowly releases the medicine into the bloodstream.
  • An implanted port is less obvious than a tunneled catheter and requires very little daily care.
  • It has less impact on a person’s activities than a PICC line or a tunneled catheter
