As an ER nurse, for IV bolus and infusions for my peds patients, I have always used an IV pump and a secondary flow control device, such as a Buretrol. In practice we would also hang a 250cc or 500cc bag to prevent the risk of fluid overload. I have seen IV pumps fail, even when programmed right and the whole liter of fluid is infused (not on a peds patient).
I am wondering what is the current standard of practice for our pediatric population. Are pediatric units using a smaller volume IV bags, 250cc or 500cc? Are flow control devices being used? Are we relying on IV pumps soley, hoping they do not malfunction.
