Types of Central Lines:
- 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
- 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.
- 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
