Can you solve this mcg to mg conversion?

I calculated it and I am baffled too. That is a lot of fentanyl. What did you get?

100 mcg to mg is 0.1

give 0.25 mg= (0.25*(2ml/0.1 mg)=5ml

give 0.5 mg= (0.5mg*(2ml/0.1mg))=10 ml

Yep, very basic math. Kudos to your for not rolling the eyes.

A very strange order though.

I got that too loveofrn. Is this for general anesthesia? LOL. I wonder if they meant to write for 0.025-0.05mg Fent?? That would make more sense.

I agree with you that it's simple, stupid math. However, Fentanyl is typically dosed in mcg, and it needs to be written that way to avoid medication errors, period.

Whoops, I even made an error in my opening post! I agree, it's confusing. I meant. 0.025 and 0.05mg! Embarrassed! I corrected it, meant to put that extra 0 in there.

Which goes to show, the pharmacy order was confusing.

I can see where he was confused, I personally only get orders to give 25 to 50 mcg of fentanyl ivp at a time...if I'm reading the post right without any typos, the doc wants a dose from 250 mcg (5 mL) to 500 mcg (10 mL)...? Talk about a Pt that can tolerate their narcs

Nothing

It can be figured out, but then again so can "Fentanyl IV pi/square root of speed of light x10 to the -24000 mcg". My biggest concern is the potential to easily misplace the decimal, which appears to the case here since the order is for 250-500mcg and 25-50 is the standard order.

The least confusing form should always be used, which means using mcg for fentanyl IV push orders since it is dispensed amounts measured in mcg. Personally I'd tell the pharmacist they need to re-write it, and I don't actually know of any pharmacist that wouldn't agree it needs to be re-written.

500 mikes of fentanyl will fix their pain along with that annoying breathing habit.

I hear the pt in question was a bit irritating...
