Drug Calculation

Question

The physician orders the patient a Dopamine infusion at 6 mcg/kg/min and titrate to keep systolic blood pressure greater than 90 mmHg. The Dopamine concentration is 400mg/250 ml and the patient weight is 80 kg. How many ml/hr will you set the infusion pump at?

Answer 1

First determine the concentration of what is in the bag.

400mg/250ml x 1000=1600mcg/ml

6mcg x 80 kg x 60 minutes divided by the concentration of 1600 mcg/ml equals:

18ml/hr
