IV push question
- 0Sep 19, '10 by desertgalI'm new to the Emergency Department. We usually start an IV bolus wide open off the pump on most of our patients. I see a lot of nurses giving IV push medications and not pinching off the tubing above the distal port when pushing medications. I've asked several of the nurses about this practice, and they've told me as long as they have an IV that's working well they won't pinch the tubing. They slowly push the drug while the NS is infusing. This gives a slow, even push. My concern with this method is that the drug could back prime up the line.
On the other hand, if you do pinch off the tubing (like all the textbooks say to do) and are giving an undiluted drug, how do you control the rate of administration? Do you push a little, release the tubing, push a little? Are both methods considered acceptable?
I know there are other threads about diluting all IV push medication with NS so that the push can be better controlled. I hope this isn't a redundant thread.

I do not pinch off, because I like the dilution factor of the maintenance fluid when I give an IVP.
Besides, even if it did backflow, once you're done pushing it and the maintenance fluid is running again, it will all go right into the pt anyway.Last edit by klone on Sep 19, '10
- 0Sep 19, '10 by desertgalThanks for the reply Klone. One more question. If you have your fluids wide open, is it necessary to flush in between incompatible medications. I always do, but is it necessary? Does the wide open fluid provide enough flow to flush the distal port free of the first medication?

... It just doesn't matter. Go with what makes you sleep better @ night.
Me, I dilute whenever possible. Unless there is a fluid restriction just lett'er rip.
- 0Sep 20, '10 by BrnEyedGirlI don't pinch unless it something that needs to go in fast,...then I pinch and push at the closest port,....most routine meds I don't pinch and I use the port closer to the bag, because as someone else said I like the dilution factor,..I push a bit then let it run a bit, push a bit etc,....and if I do it this way then no I don't bother with a flush as the line is being flushed with the fluids,..you could always draw from the bag and flush if it really bothers you.
- 0Sep 20, '10 by simbokaBack priming's not a concern for two reasons: the pressure from the fluids will push it in, especially if the bag's high and wide open; or when you finish the fluids will flush it. I've given colored pushes through free flowing fluids, and it's not gone up any significantly up. Our tubing does have a one way valve below the main bag of fluids.
Definitely need to flush between, we actually just had an inservice by some tubing people, and she said up to 0.1mL can stay in a luerlock port on tubing.Last edit by simboka on Sep 20, '10 : Reason: Additional info
