While IV lines are generally safe, they do carry some risks, including: - Infection: Insertion can introduce bacteria into the bloodstream, leading to infection. - Phlebitis: Inflammation of the vein, often due to the catheter irritating the vein wall. - Infiltration: Fluid leaking into surrounding tissues if the catheter dislodges from the vein. - Air Embolism: A rare but serious complication where air enters the bloodstream.
