What is a Saline Flush?
A saline flush is a medical procedure involving the injection of a sterile saline solution into a catheter or intravenous (IV) line. The saline solution is typically a mixture of sodium chloride (salt) and water, closely mimicking the body’s natural fluids. This process is essential for maintaining the patency (openness) of the IV line, ensuring that it remains clear and functional for administering medications, fluids, or nutrients.

Why is a Saline Flush Important?
- Maintains IV Line Patency
One of the primary reasons for performing a saline flush is to keep the IV line open and functional. Over time, blood or medication can accumulate in the line, potentially causing blockages. A saline flush helps clear out these blockages, ensuring the line remains open for future use.
- Prevents Infection
By regularly flushing the IV line with saline, healthcare providers can reduce the risk of infection. Stagnant fluids within the IV line can become a breeding ground for bacteria, leading to infections. Saline flushes help prevent this by keeping the line clear and sterile.
- Ensures Proper Medication Administration
When medications are administered through an IV line, it’s crucial that the line is clear and unobstructed. A saline flush ensures that the medication can be delivered effectively, without any interruptions or blockages.
- Reduces Discomfort for Patients
Patients with IV lines often experience discomfort if the line becomes clogged or blocked. Regular saline flushes help reduce this discomfort by ensuring the line remains clear and functional.
