After talking to a very respected medic in the company, they taught me an easy way to calculate a dopamine drip for a patient as long as you are using the standard 1600mcg/ml bag (double the drips for a 800mcg/ml bag). For every 5kg you add 1 drop. so a patient weighing 100kg would get 20gtt/min at 5mcg/kg/min. (I worked the math out myself and it works perfectly). Just thought someone might appreciate that sometime or another, I know I did.

Although there is nothing wrong with doing the above, I prefer to be exact, because I used to work on a neonatal transport team, where we would frequently make the concentration of drugs much higher to reduce the amount of drops that had to be delivered, in that situation you could not "spit-ball" the dosages, so here is an easy way to be exact:

Multiply everything together and divide by the concentration:

Mcgs you want to deliver x Patient KG x 60 / concentration

So if you want to deliver 10mcg to a 50kg patient, 10x50x60= 30,000 / 1600 = 18.75

This formula works for all dosages and all concentrations, and you will amaze everyone as most charts round up 1-2 drops.

Yea if im setting up a med drip i use the Dosage needed to be given, times, drop set, divided by concentration like you stated earlier. I use my calculator usually so my drops are correct because I have alot of trouble working with big numbers in my head, and usually if I'm doing a drip like dopamine I don't have time to get a piece of paper and pencil to write it out.

Except for those rare folks that have pumps it's always 'spit balled' though, right?
