mg/min (For example - Lidocaine, Pronestyl) Solution cc x 60 min/hr x mg/min Drug mg = cc/hr Drug mg x cc/hr Solution cc x 60 min/hr = mg/hr Rule of Thumb Lidocaine, Pronestyl 2 gms/250 cc D 5 W 1 mg = 7 cc/hr 2 mg = 15 cc/hr 3 mg = 22 cc/hr 4 mg = 30 cc/hr mcg/min (For example - Nitroglycerin) Solution cc x 60 min/hr x mcg/min Drug mcg = cc/hr Drug mcg x cc/hr Solution cc x 60 min/hr = mcg/hr Rule of Thumb NTG 100 mg/250 cc 1 cc/hr = 6.6 mcg/min NTG 50 mg/250 cc 1 cc/hr = 3.3 mcg/min mcg/kg/min (For example - Dopamine, Dobutamine, Nipride, etc.) To calculate cc/hr (gtts/min) Solution cc Drug mcg x 60 min/hr x kg x mcg/kg/min = cc/hr Example: Dopamine 400 mg/250 cc D 5 W to start at 5 mcg/kg/min. Patient’s weight is 190 lbs. 250 cc 400,000 mcg x 60 min x 86.4 x 5 mcg/kg/min = 16.2 cc/hr To calculate mcg/kg/min Drug mcg/ x cc/hr Solution cc x 60 min/hr x kg = mcg/kg/min Example: Nipride 100 mg/250 cc D 5 W was ordered to decrease your patient’s blood pressure.
