Worried...did not clamp main IV line. - Page 2Register Today!
- Feb 28, '11 by HappyParamedicRNmost IV tubing has a built in fi.ter to prevent backpriming if that is what you mean. I wouldnt worry about it.
- Feb 28, '11 by EDrunnerRNNever worked the PCA pumps as I am an ER nurse but how much could you have really gave him just by adding a little pressure 2 mg? Its an IV medication so you would have seen pretty immediate changes in VS if you really gave him a big bolus. Now ya got me interested in how these things work...might take a trip to the ICU tomorrow...
- Feb 28, '11 by CCL RNDon't worry. You would have to push down on the syringe to give any kind of bolus. Do you not have a second RN do syringe changes with you?
Although this was an isolated event (hopefully), just get into the habit of always clamping lines when you are changing syringes, pumps, etc. For regular tubing, You don't want to change an insulin gtt, or levophed gtt over to another pump and accidentally bolus that.
And for all who say there is a built in latch to prevent accidental boluses, at least on regular alaris tubing, I have seen that fail. (I do realize we are talking about PCAs here, but I wanted to emphasize that we can't always rely in back up measures..)
So, especially in the ICU, get used to clamping...
- Mar 2, '11 by MunoRNYou are correct that it is possible for the PCA med in the tubing to free-flow when disconnected from the syringe since there is no upstream closed system, although it's unlikely. The PCA tubing we use has no clamp on it, what I do is to stop the fluids I have the PCA running in to while I change the syringe, which is probably a good habit, but in the time it takes to change the syringe it's unlikely that a large amount could infuse. Even if the whole line were to empty (and I've never seen it flow even a tiny bit), the tubing we use has a volume of only 0.2ml
