drug calculation problem

I want to work in the ICU, and I noticed that some drugs are given in mics per minute. Does anyone know the formula, so that I can figure this out. I think that it is a calibration formula. Thanks in advance.

do it exactly how you would do Mg per minute. Like figuring out a Lidocaine drip.

First, you do know that mic stands for micrograms.

Sometimes dealing with "strange" drug amounts like mics, units, etc will throw you a curve.

Here is a nice site with plenty of drug formulae and calculations.

here is another link just for S & Gs you can never learn your calc too well

this is how I learned:

To find the rate if you know the dose (amt. desired):

Amt of drug(mg or units) / Amt of solution (cc's) x 1000 = A

then

Amt desired (dose) / A x wt (in kg's) x 60 (for min)

ex: start 5mcg Dobutamine, pt wt is 70 kg

500 / 250 x 1000 = 2000

5 / 2000 x 70 x 60 = 10.5 cc

to find the dose if you know the rate:

Amt drug (mg, units) / Amt of solution (cc's) x 1000 x rate /wt /60

ex: rate is 10 cc, wt 70 kg. How many mcg of Dobutamine?

500/250 x 1000 x 10 / 70 / 60 = 4.7mcg/kg/min

Hope this helps.
