A patient with multiple fractures has an order for 2L of D51/2 NS each to contain 20,000u of heparin to?

Question

infuse at 50ml/hr using a microdrip?????

Answer 1

I'm not sure what your question is....

Why is this done?  To prevent deep-vein thrombosis.

How much heparin to mix?  20,000 units in each one-liter bag.

How much heparin is the patient receiving?  20,000 units divide by 1000 mL = 20 unit/mL.  So 50 mL/hr x 20 units/mL = 1000 units/hr, which is the standard maintenance dose (often after a bolus of 5000 units).

Anyway, perhaps next time you can  make it clearer what it is that you want to know....

Good luck!
