How to Flush a Groshong Catheter: Step-by-Step Guide

A Groshong catheter is a type of central venous catheter that is commonly used for long-term intravenous therapy. It is important to properly flush the catheter to maintain its patency and prevent any complications. In this article, we will provide you with a step-by-step guide on how to flush a Groshong catheter.

Step 1: Gather the necessary supplies

Before starting the flushing procedure, make sure you have all the required supplies within reach. These may include sterile saline solution, a syringe with a luer lock, an alcohol swab, and gloves. Ensure that all the supplies are sterile to prevent any infections.

Step 2: Wash your hands

Proper hand hygiene is crucial when handling any medical procedure. Wash your hands thoroughly with soap and water or use an alcohol-based hand sanitizer to reduce the risk of contamination.

Step 3: Prepare the saline solution

Take the sterile saline solution and attach the syringe with a luer lock to it. Make sure the syringe is securely attached to prevent any leakage during the flushing process.

Step 4: Position the patient

Ensure that the patient is in a comfortable position, preferably lying down. This will help to prevent any discomfort or complications during the flushing procedure.

Step 5: Clean the catheter site

Using an alcohol swab, clean the catheter site in a circular motion. Start from the insertion site and move outward to remove any dirt or bacteria. Allow the site to air dry before proceeding.

Step 6: Flush the catheter

Hold the catheter hub securely and gently attach the syringe filled with saline solution to the catheter hub. Slowly and steadily push the saline solution into the catheter while maintaining a constant pressure. Avoid using excessive force to prevent any damage to the catheter.

Step 7: Observe for any complications

While flushing the catheter, observe for any signs of resistance, pain, or swelling. If you encounter any difficulties or notice any abnormalities, stop the flushing procedure immediately and seek medical assistance.

Step 8: Dispose of the supplies

Once the flushing procedure is complete, dispose of all the used supplies in an appropriate manner. Follow the proper disposal guidelines to ensure safety and prevent the spread of infections.


Flushing a Groshong catheter is a crucial step in maintaining its functionality and preventing complications. By following this step-by-step guide, you can ensure a safe and effective flushing procedure. Remember to always consult with your healthcare provider for specific instructions and guidelines related to your individual catheter care.
