If a patient is ordered an infusion of 12500 units from stock solution 1000u/s per ml and made up to 50ml with normal saline. Would it be 12.5 heparin to draw up and 37.5 saline??? How would I work out the rate of infusion if it is to be administered over 12hours??
I feel like I'm missing something here. Are you giving it from the iv stock solution or are you trying to use it to give an injection? Or are you adding the heparin to saline? And don't you have a pharmacist that supplies it at the dose you need? Truthfully I haven't seen a nurse having to figure this out in a long time. To figure out the rate you would take the total amount of the fluid and divide it by 12 and that would be the number of ccs/hr. If you're mixing it to give iv, you would do as you said, the 12.5 of heparin and the rest saline. I don't see how you are going to give that small of an amount an hour, unless you are using an iv pump. I'd want it in 500 ccs of saline, if it had to be given over 12 hrs.
From a standard bag 12500u/hr would be 12.5cc/hr. To see how long the bag would last divide 1000 by 12.5 To give a bolus from a bag you would draw up 12.5cc from the bag. Not sure where your getting 37.5 cc of saline from
