A sodium flush, using a sodium chloride solution (saltwater), is a procedure used to clean and maintain intravenous (IV) catheters, helping to prevent blockages and remove residual medication.
Here's a more detailed breakdown:
-
Purpose: The primary purpose of a sodium flush is to ensure the IV catheter remains open and functional. It achieves this by:
- Preventing Blockages: It clears any potential obstructions forming inside the catheter.
- Removing Medication Residue: After administering medication through an IV line, a flush helps ensure no medication remains in the catheter, potentially reacting with subsequent drugs or causing localized irritation.
-
Composition: The solution used for a sodium flush is typically sterile sodium chloride, also known as saline solution. The concentration is often 0.9% (normal saline), which is isotonic and well-tolerated by the body.
-
Mechanism: The fluid pressure from the flush physically dislodges any debris or medication buildup within the catheter.
-
Benefits: Regular flushing of IV catheters offers several benefits:
- Reduced Risk of Infections: Flushing helps maintain cleanliness and reduces the risk of bacteria colonizing the catheter.
- Prolonged Catheter Lifespan: By preventing blockages, flushing extends the usable life of the IV catheter, reducing the need for replacement.
- Improved Medication Delivery: A clear catheter ensures medications are delivered effectively and consistently.
In summary, a sodium flush is a vital procedure for maintaining IV catheter patency, preventing complications, and ensuring effective medication administration.
