about flushing a saline lock
- 0Nov 26, '08 by Amy2005This is a procedure that I am finding some information
about on the Internet. One source said that the flush
is to be gentle.
Another source said to create turbulence (using push-pause).
Which is suitable?
Is there a video that will demonstrate?

Push-pause method is used for central lines only, which creates turbulence. You also want to make certain to use nothing smaller than a 10ml syringe. This is because the smaller syringes will cause too much pressure and can damage the line.

- Check Dr.’s order/MAR for frequency
- Draw up 2cc saline (or use a pre-filled syringe)
- Check patient's armband/ID
- Check site for: swelling, redness, pain, temperature
- Note: gloves do not have to be worn unless there is potential for blood contact
- Connect syringe to adaptor
- Aspirate back gently (if you get blood return, then try to inject the saline gently. If it flows easily, continue. Make sure to watch the site for swelling and assess for any pain)
- If you meet resistance, stop and reassess. It is recommended that you reposition arm and gently manipulate site before attempting to aspirate again. If you get blood return when attempting to aspirate a second time, then continue with the procedure. If there is still no blood return, attempt to inject the saline. BUT, do not try to push against resistance. If you meet any resistance, you'll likely have to restart the site.
- It is important not to give any IV meds though a saline lock without checking the patency first
- Patency should be checked at least once a shift

- 0Nov 27, '08 by MedicalNerdAny time I have flushed a SL I used the 10ml syringe and was gentle with the pressure. If I met resistance I would apply slightly more pressure but if there was still resistance I would call the RN or my instructor. It is hard sometimes to know how much pressure is needed VS how much is too much. I think it will come with experience.
