How do you calculate dobutamine infusion rate?

It means if we add 0.9 ml of dopamine in 24 ml of fluid and give @ rate of 1 ml/hr with syringe pump or 1 microdrops per min (which is virtually impossible) with the micro drip set, we will give dopamine @ 10 mcg/kg/min. needed for this baby in 24 hours=100×2. 5=250ml/day. Fluid to be given every 8 hours = 85 ml.
