Your patient is a 47 year old male with wide complex tachycardia. Medical command orders a lidocaine infusion of 2 mcg/min. You choose a micro drip set ( 60 gtt/mL).
Dosage on hand for lidocaine 2 grams / 500 mL.
What is the concentration of this IV bag of lidocaine in mg/mL?
How many mL/he are needed?
How many drops per minute are needed?
How many drops per second are needed?
Homework Answers
Concentration of IV bag in hand= 2 gm/500 ml
= 2000 mg/500 ml ( as 1 g= 1000ml)
= 4mg/ml
Ordered lidocaine= 2 mcg /min
= 120 mcg/ hr (1 mg = = 1000 mcg
= 0.12 mg/hr
4 mg in 1 ml
Then 0.12 mg will be in= 0.03 ml
Hence ordered lidocaine infusion in ml/ hr = 0.03 ml/hr
Infusion rate in gtts/min= ( total volume in ml/infusion time) X drip rate in gtts/ml
= (500/60) X 60
= 500 gtt/min
= 8.5 gtts/second
