You are to start a Dopamine drip at 2.5 mcg/kg/min for renal perfusion. The patient weighs 150 lbs. The stock from the pharmacy reads Dopamine 400 mg/500 mL D5W.
What is the flow rate in mL/hr?
Orderd Dopamine drip at 2.5 mcg/kg/min
Patient weighs= 150 lbs= 150/2.2kg= 68.18 kg
As per weight of the patient required dose= 2.5 X 68.18=170.45 mcg/min
Available Dopamine= 400mg/500ml
=0.8 mg/ml= 800mcg/ml
800mcg in 1 ml
1 mcg in= 1/800 ml
170.45 mcg in = 170.45/800 ml=0.213 ml
Hence 170.45 mcg/min= 0.213 ml/min
= 12.78 ml/hr is the required flow rate in ml/hr.
