Which procedure might involve phlebitis as a complication?

Phlebitis is an inflammatory reaction of the vein, which can occur as a complication of intravenous therapy. This procedure involves the insertion of a catheter into a vein to administer medications or fluids directly into the bloodstream. If the catheter irritates the vein, or if there is an infection or inappropriate placement, it can lead to phlebitis.

When performing intravenous therapy, it's important for medical professionals to monitor the site for any signs of inflammation, pain, or redness to prevent and address complications like phlebitis promptly.

While blood transfusions can also lead to complications, such as transfusion reactions, they are less frequently associated with phlebitis compared to intravenous therapy. Emergency surgery and CT scans do not typically involve direct access to veins in the same way that intravenous therapy does, making them less related to this complication.
