Ok, my hospital has a very confusing heparin protocol. For example:
Patient weighs 86.4 kg
Initial rate started at 1000 units/hr (12 units/kg/hr) per pharmacy
The heparin bag is 25,000 units in 250 ml
So starting rate is 10 ml/hr
Now the fun begins:
aPTT is 40 sec
Protocol on MAR says:
If aPTT is 35-45 sec increase rate by 150 units/hr (2 units/kg/hr)
I got 12 ml/hr
I used this guide nursing.uchc.edu/.../Heparin%20Drip%20Calculation%20Reference.pdf
Or do you simply add 150 units to the 1000 units/hr for an answer of 11.5 ml/hr?
Thanks!
