Kcl

[Bee2008]

can kcl 40 meq in 1000ml @ 150/hr & k phos be ran together? or too much k at one time? please clarify. thanks.

K+ should be infused at no more than 10mEq/hr.

[DjMiG, BSN, RN]

K+ should be infused at no more than 10mEq/hr.

That is unless you have a central line and the patient on a monitor. Then you can increase to 20 mEq/hr.

As for the original posting, You should probably refer that question to a pharmacist. IMHO, figure out how many total mEq's of Kcl you have total running and figure it out from there. Am i mistaken? Anyone?

[Virgo_RN, BSN, RN]

The OP is too vague. It really depends on the specifics.

For example, if you have K+ 40mEq/1L infusing at 150mL/hr and 30mM of phosphorus with 44mEq of K+ in 500mL diluent infusing over 4-6 hours, then how much K+ is the patient getting per hour?

Much easier to run it by the pharmacist. I like figuring out the puzzle for myself, though (then double check with the pharmacist to make sure I'm on the right track!).

What is the concentration of the kphos?

How fast are you infusing it?

Does the patient have a central line?

You're already running KCl at 6mEq/hour...so calculate accordingly, taking the above questions into consideration. Remember, max K of 10mEq/hour peripherally or 20mEq/hour with central line as the other poster stated.

We really need the concentration of KPhos here. I'm thinking though that I'd run a separate line for the KPhos. I usually run KPhos more slowly than my KCL.

for the problem above, will the pt then be getting about 13meq/hr of kcl (is my math right?)

don't remember the details of the kphos order (may be 15mmols over 6hrs via peripheral iv) since it was written right before change of shift. so i just signed it off to the next shift & told them to check if too much k may be running if infused together

It's 13.3mEq/hour, and that's too fast in a peripheral IV (assuming you chose the slowest 6 hour infusion for the kphos). It (kphos) needs to be slowed down to infuse over 11 hours minimum else the 40mEq needs to be adjusted while the kphos infuses over 4-6 hours. Sounds like a new order needs to be written altogether for both of these...

The simplest solution is to hang a bag of fluid w/out KCl while the kphos infuses and then switch it back after completion.
