Parenteral Nutrition via PICC Line
Sometimes parenteral nutrition is given via a different type of line than a CVC and a PICC line or Peripherally Inserted Central Veneous Catheter is used.
A PICC line is similar to a CVC in that the internal tip is located at the top of the heart, but it enters the body via a vein in the middle of the arm and this is where the external port is located.
Your healthcare team will make the decision on which type of line would be most suitable for you, taking many things into account, such as how long you are likely to require parenteral nutrition for, whether you have suitable sites for proper access, your medical history, etc.
The PICC line is used in much the same way as the CVC and still requires the use of an asceptic technique when accessing (which should be inline with your hospital/healthcare trust).
