thanksWhat is the gist of piggyback infusions?
Piggyback infusions are solutions or dilutions given through a inferior line. The primary queue would be the infusion directly connected to a tubing going to the the venous access. The piggyback is going through another set which tubing will be connected to the injection port of the main procession. When piggyback infusion is given, the piggyback unit is hung on an IV pole at lowest 6 inches higher than the primary container.
You enjoy a main IV infusion going--such as something as simple as middle-of-the-road saline and you need to run a second, small medication surrounded by, such a gentamycin; you get the small antibiotic purse and attach its tubing into the main IV portal at a Y and run together--essentially using the NS as a mover for the gent. Some times you have fluid precincts a patient can achieve so piggybacking is a way to minimize fluid loads. Some times the IV is acerbic and a piggyback will help dilute it. Most exalted when piggybacking is that both solutions are compatible and will not cause a precipitate. (This is one use why you can't piggyback onto blood or TPN).
a piggy back infusion mode the medicine is one given secondary to an existing infusion. some medicine need to be diluted near water for example. So if you hold an iv infusion of water already running, i would start the second medication to run surrounded by conjunction with your existing med. or piggy spinal column it.
A primary infusion would be one thats running continuously such as sodium cloride and and piggy back or secordary shoulder bag would be hung at a specific time (such as a antibiotic) for a short duration, usually a hour. The primary would kick surrounded by after the secordary is complete
