Unless your patient in on death row, no, K+ is never pushed fast.

Until this year, we used to draw up and add mgso4 and cacl to 25 ml bags ourselves to administer to a patient for replacement, but in response to JCAHO's goals in 2004 for "medication management standards", we now have the little 25 ml bags in our pyxis refrigerated unit stock premixed by the pharmacy. I LOVE it....one less thing for me to do!

In general we have less pre-mixed drugs than you seem to. Some of our wards are going to the pre-mixed KCL bags but in ICU where the needs are very volatile and we need to get stingy with fluid we will mix it ourselves - usually on an hour by hour basis taking electrolytes again every so many hours depending on the amount we have given.

When people ask about working in Australia - this is one of the differences they encounter. And Potassium is ALWAYS given through an electronic pum like an IMED.

However our clinical path for CHF patients has oral K for replacement as the first choice. It seems back 5+ years ago all the doctors were doin IV replacement now most are doing oral.

I remember one patient we had who had a K in the high 2.0 range and because we could only give 10meq and hour we couldn't ever catch up. We ulitmately asked for an oral order and after 3 days of trying to catch up and never getting above 2.8 using IV we got our first K of 3.5 4 hours after oral replacement. You can give a lot more orally over a shorter time than IV. Obviously this will only work if the patient isn't npo or nauseated etc.

?why does the oral K work faster than the IV route?

It may not actually work faster but you can give more meq's over a shorter time. You can give 40meq of powder or tablets at a time, but it would take 4 hours with my hospita's protocol to give the same amount IV.

IV K+ works immediately (important when replacing electrolytes to address ectopy) while PO K+ takes, on average, about 30 minutes minimum to kick in and most if not all forms of PO K+ are extended release so it's effectiveness occurs over time. The effectiveness of PO K+ also really depends on how well the person's gut is working. If their absorption is compromised for whatever reason, PO K+ may not work well at all.

When we give PO K+, the dose is usually 1 1/2 - 2 times what we would give if we were giving it IV.

If patients are complaining about KCl riders, I slow down the rate, and/or put a bag of ice at the IV site. I don't put it directly on the skin though. I generally place a washcloth between the ice and the patients skin. I hope this helps.

Are there any more tips for alleviating the burning? This is frustrating to me because it takes sometimes an entire shift for a 100cc bag to infuse because the pt is complaining of burning.

Does yourIV pump have a concurrent setting? This way you can run your large volume fluid at 80-100cc an hr. Then set your k-rider at 25cc an hr. to finish in 4 hrs. If you can't run concurrently, then you need two IV pumps, hang the k-rider on separate pump and connect to large vol.IV on other pump at the lowest injection port on the tubing, use primary tubing for the k-rider, this way the pt is getting both fluids simultaneously and the K-rider is being diluted by the large vol. IV fluid.

Our standing orders were to add 1 amp of lido to each bag of KCl. We were fortunate to have great standing orders written by one of the more progressive cardiology groups in the Chicago area.

You can check with Midwest Heart. I believe they are located out of Downers Grove, IL. I know they have shared their standing orders in the past. Their URL is:

Good luck!

First, check to see if you have a patent IV! If you have 2 IV's, try not to give IV K in the hand !! (Personal experience- it hurts like heck!!) The best way to alleviate burning is to slow the rate of the potassium down-don't increase the rate of the saline (unless there is an MD order to change the rate) because that too can cause burning! ALWAYS ALWAYS ALWAYS run IVPB's of potassuim via pump! If given too quickly, can cause bad (and possibly lethal) outcomes!
And remember there will always be those pts that no matter what you do, the IVF will be uncomfortable- Ice does help!!
Good Luck!

i find the premixed 10 meq kcl in 100cc d5w have all the pts complaining but when pharmacy mixes 100 meq in ns the complaints are rare--there is no kcl vials allowed on the medical floors, we can only run 1o meq in 100cc over an hour on the floors--if higher strengths needed, the pt must go to icu---maximun in large volumes is 40meq in 1000cc at not more than 125cc hour
