A common cause of phlebitis is?

Prolonged use of the IV catheter is indeed a common cause of phlebitis. Phlebitis refers to the inflammation of the vein, which can occur when an IV catheter is left in place for an extended period. The risk increases because the longer a catheter remains in a vein, the greater the likelihood that it will cause irritation to the surrounding tissues due to movement, chemical irritation from the infusate, or infection at the site.

When an IV catheter is maintained beyond the recommended duration, especially if it is not routinely assessed and secured, it can lead to the development of phlebitis, manifesting as redness, swelling, warmth, or pain at the insertion site. This highlights the importance of following protocols for catheter care, including timely assessments and removal of IV lines as indicated, to minimize the potential for complications such as phlebitis.
