What is the purpose of flushing an IV catheter?

Flushing an IV catheter primarily serves to maintain catheter patency, which is essential for ensuring that the catheter remains open and functional. This process involves using a sterile saline solution to clear any obstructions, such as clotted blood or precipitate from medications that may have settled in the line. Maintaining patency is crucial because a blocked catheter can lead to complications, such as phlebitis or an inability to deliver medications or fluids as needed.

Regular flushing also helps to ensure that the catheter remains free of debris and that the connections are secure, which promotes both the efficacy of therapy and the safety of the patient. By performing this routine maintenance, healthcare providers can enhance the overall effectiveness of intravenous therapy and reduce the risk of complications associated with catheter use.
