One general guideline for the maintenance dosing of heparin in
pediatric patients is 100 units/kg every 4 hours, or 20,000
units/m2/24 hour administered continuously. The
available injection for use by intravenous infusion contains 1000
USP Heparin Units/mL. For a 44-lb child, measuring 42 inches in
height, calculate the difference between the quantities of
heparin administered over a 24-hour period in (a) heparin units,
(b) in milligrams of heparin (sodium), and (c) in milliliters of
heparin injection.
