IV therapies are performed using either an IV catheter or a butterfly needle. An IV catheter is a small plastic tube that is inserted into the vein using a needle. The needle is removed and the small plastic catheter remains in the vein, which is then stabilized to the skin with a dressing. IV catheters are referred to as heplocks, which can stay in place for up to four days.
A butterfly needle is a small rigid needle that is inserted into the vein, stabilized to the skin, and remains in place throughout the treatment. This is a temporary access used for short term treatment.
For longer term IV treatment, a PICC line or Port may be installed, both of which can remain in place for as long as treatment is needed.
