Mind gone blank :/ help with calculations please :-)

Hello everyone,

Okay so I seem to be having a blank moment, and can't seem to work out the answer to these calculations. I guess I just need a quick break down of how to work out the answer, and hopefully I will remember it all again.

1) For this question, I want to work out the mls per hour:

Epinephrine (Adrenaline)

5mgs (5mls) in 95mls of Dextrose 5% to run at 0.04mcg/Kg/min. (Patient weight= 65Kg)

2) If a patient is on lets say 10mls of Epinephrine (Adrenaline) an hour. How do I work out how many mcg/Kg/min is that (if there is 10mgs of Epinephrine in 90mls of Dextrose 5% and patient's weight is 95Kg)?

If anyone reading this is able to give me a mini tutorial on how to work the above answers, I would be forever grateful.

Thank you in advance, for taking the time to read this

Yep, you need 156 mcg/hr, so you're on thr right track. Next you need to figure out how many mcg you have per milliliter so that you can figure out your flow rate.

We have converted the mcgs to mgs so we need to figure out how many mgs per ml.

yes.....now you need find out how many mcg/ml you have available in the bag. Remember your conversions.

You have 5mg in 95ml. Now find how many mcgs.(5,000mcgs)

Dear Esme12,

Thank you :-)

100ml x 60 x65kg x0.04= 15600 then divided by 5,000mcg equals 3.12 mls/hr is this correct or should I have converted the 0.04mcg into mg?

NO...leave the measurement that you are going to need /give alone......always convert the problem to the measurement to desired med...ending answer.... is in because that is the goal where you want to go and the patient is to receive.

See you did know how to do it!

To really lose your mind you have to be a lot more experienced. :) We can help with that.

(just kidding)

Good thinking!
