I'm a student
so please bare with me
So I watcheed a piggyback actually being set up for the first time at clinical. I then came across a PB skills video, and now I'm a little confused. I was used to the "traditional" PB method and that's what I was taught and saw for the first time last clinical; however on the video, the "piggyback" was simply hung at the same height as the primary and both were run at the same time (with the secondary tubing going into a second port on the patient--I've seen some patient's with multiple IV access sites). What I am confused on is: when would you hang a "traditional" piggyback (med bag above primary bag, secondary tubing going from piggyback connected to primary tubing at Y-port, back valve prevents flow of primary while PB med/solution is infusing) and when would you just infuse both primary bag and "piggyback" bag at the same time? Now that I'm confused, I'm looking into this more and wondering exactly why
that we don't run both infusions at once (what's the point of having the primary stop while the piggyback runs in, why not run them in simultaneously if they're compatible and the patient is not CHF, renal failure, etc).
I plan on asking my instructor, but everyone on this board is so good at explaining (and besides--I'm a type A personality and can't wait till clinicals to find out the answer!:chuckle ). Any thoughts/explanations are certainly appreciated greatly! IVs terrify me!
Hope you all are having a great weekend!
