- 1Jun 7, '11 by ashonmanSo I found out I am so rusted, I need help with the following drip calc. guys please help a girl out.
1. Order reads infuse Epinephrine @ 30ml/hr. The solution available is 2mg of Epi in 250ml D5W Calculate the following
a. Mg/hr b. mcg/hr c. mcg/min
2. A Nitro Drip is infusing at 3ml/hr. The solution avail is 50mg/250ml Calculate mcg/hr and mcg/min. I know this its 5mcg per hr but the problem is how do you get there. its something I need to review for myself. Somebody pls help.
- 0Jun 15, '11 by t2kckYou have 2mg in 250cc, therefore how many mcgs are in a mg? How many min in a hr? How many cc's in hr? How many in the solution.... It is basic math. It is not calculus.
You are making it too hard.
Your answer to #2 is wrong. Try again. Ask a student to help. You are going to slap your forehead when you get the answer.

1. a. If 250ml of D5W contains 2mg, it follows therefore that 30ml/hr will have 0.24mg/hr i.e (2mg x 30ml/hr) /250ml.
b. Now we know that 0.24mg/hr = 240mcg/hr i.e If 1mg = 1000mcg therefore 0.24mg/hr = 240mcg/hr
c. We know from b above that epi is running at 240mcg/hr = 4mcg/min
2. Use same logic as above and you will arrive at 0.6mg/hr and 10mcg/min.

a. mg/hr=2mg/250ml x 30ml/hr=60/250 = 0.24mg/hr
b. mcg/hr=1000mcg/1mg x 2mg/250ml x 30ml/1hr = 60000/250 = 240mcg/hr
c. mcg/min=1000mcg/1mg x 2mg/250ml x 30ml/1hr x 1hr/60min = 60000/15000 = 4mcg/min
*****dimensional analysis, learn it and you can work out most any dosage!
apply to next q:
a. mcg/hr = 600mcg/hr
b. mcg/min = 10mcg/minLast edit by CRIMSON on Oct 10, '11 : Reason: easier to read?
