Flushing a cannula involves using a gentle push-pause method to introduce a saline solution, clearing any obstructions and maintaining patency.
Steps to Flush a Cannula
-
Prepare: Gather necessary supplies: saline flush solution (pre-filled syringe is recommended), appropriate size cannula, and a sharps container.
-
Clamp (If Applicable): If your cannula has a clamp, open it. This allows for easier flow of the solution.
-
Flush: Attach the pre-filled syringe to the cannula. Gently push the plunger, injecting the saline solution. Pause to allow the solution to flow. Repeat the push-pause method until the syringe is empty. This gentle, intermittent pushing avoids excessive pressure, which could damage the cannula or surrounding tissues. The video, How to Flush an IV Catheter - MedStar Visiting Nurse Association - YouTube, demonstrates this technique.
-
Remove and Dispose: Once the flush is complete, untwist the syringe from the cannula and dispose of it safely in a sharps container.
-
Clamp (If Applicable): If your cannula has a clamp, reclamp it after flushing.
Important Considerations
- Use the correct solution: Always use sterile saline solution for flushing a cannula. Other solutions may be harmful.
- Gentle pressure: Avoid forceful pushing of the plunger. Gentle pressure is sufficient.
- Observe for complications: Monitor the cannula site for any signs of bleeding, swelling, or discomfort after flushing.
- Professional guidance: For specific instructions or if you have concerns, consult a healthcare professional.
The method described above is based on the technique shown in the provided video clip from MedStar Visiting Nurse Association's YouTube video on how to flush an IV catheter. While the video demonstrates IV catheter flushing, the principles are similar for flushing other types of cannulas. Remember to always follow your organization's specific protocols and guidelines.
