Hey all

I have been a nurse for 5 months, telemetry floor, although we have a large # of "why is this person on the tele floor?" pts. So starting cardiac drips is not a something we do regularly and it was certainly my first time receiving an order to start an Amiodarone drip. I was not comfortable about starting a such a drip by myself so I went to the charge to help with the calucalation. I had 5 other very ill pts, so by the time I came back to the pt's room, my charge had already calculated and had the drip running. I need help in calculating those drips in order to become more comfortable . We run all fluids on IV pumps in ml/hr. Yesterday's order was:

Amiodarone IV bolus at 150mg over 1 minute, then 1mg/min for 6hours and then 0.5mg/min for 18hours. What is the simpliest method to calculate this into ml/hr.

Note: Pharmacy sent the bolus in a separate 100 ml bag and the continuous drip in a 500 ml bag.

I feel lost with calculating drip rates and sincerely need your help.


tks

how many mg in the 500ml bag?

thanks for responding. Only thing, I can't remember how many mg was in the 500 ml bag.. Hypothetically, how do I set up the calculation to get the ml/hr rate to run the drip?

[nurselizk]

rate = (1 mg/min)x(500 mL/#mg in bag)x(60 min/hr)

Aren't your IV pumps programmable?
After a while, you'll get to know the drip rates. For example, for us, 1 mg/min is 50 mL/hr. But always check your concentration to verify it's the same as the bag that's hanging, or you might need to change the rate.

Amio is standardized. Always comes in 500ml bag. Order is always the same (unless more frequent bolusing). Your 150 bolus goes in over 10-15 min program for 600-900/hr. your 1mg/min is always 33.3 cc hour, program a VTBI of 199-200 to remind you to turn down after 6 hours, your 0.5mg/min is 16.6 cc hour. This really is standard for amio.

Ours is always 300 mg in a 250 mL bottle. I was just saying that she'd get to know what is standard at her institution, but that SOME drips can be made up in different concentrations. Our Levo is typically 4 mg in 250 mL, but a patient on 12 different drips might have them double or quadruple-concentrated to reduce the fluid intake. Be careful of thinking that what is standard at your institution is standard everywhere. And I've taken over patients with pumps mis-programmed because someone didn't bother to check the bag before hanging it.

With only 250cc at 1.2mg/ml. You guys must run out of this alot during a 24hr infusion, you can't even finish your 1st 6 hr dosing.

Concentrations are NOT standardized across the country. Our amio runs at 18ml/hour and 9ml per hour.

Wouldn't it be grand if they were standardized across the country, as well as IV tubing, etc.
