we run iv protonix over 15 min. comes labeled from the pharmacy that way, though i think it comes in 50 cc, rather than 100 cc.
as for running it too fast through a 22g, the only problem really would be if the size of the catheter prevented it from going that fast. really, unless you are using a power injector (like they do for some ct scans) or have high pressure limit on your iv pump set way high, the max rate for a particular size iv is self-limiting. that is, if you are trying to infuse something too fast, the iv catheter won't let you. if the rate is too high for the catheter size,l the pump will generate too much pressure in its attempt to infuse, causing the pump to alarm.
hope this makes sense.
i think i'd ask to see a copy of the policy you violated. since you were unable to find it, and it must exist
, your supervisor needs to show it to you, and show you where to find it, in case you have questions in the future.
by the way, i work in an outpatient infusion center, and the vast majority of the ivs we start are 22g. i've never seen an 18g (we don't do blood), and a 20 g is rare. we're more likely to do 24s than 20s. we do many infusions that run faster than 200 cc/hr. in fact, the standard mix of vanomycin is in 250 cc ns, and it is usually run over one hour. if we run it through a peripheral line (central line is preferred, but we can do it through a piv for short-term), it is usually through a 22g, since the smaller catheter size allows blood flow aroud the iv catheter, causing better hemodilution of the vanc, and less risk of phlebitis.
so, that max rate on a 22 g may be hospital policy, though i'd doubt it until i saw it in writing. if it really is policy, it really needs to be changed!
