Heparin is a medication that prevents blood from clotting. In the adult population, it is used as an anticoagulant and given in much higher doses than it is in the neonatal population.
In the NICU, it is only used for one thing - to keep IV lines from clotting. We use PICC/PCVC lines and umbilical lines in these babies that are as thin as dental floss. Becuase the inside of the line is so tiny, we need to make sure it doesn't clot off with blood so that the IV nutrition and medications can get to the baby. All the heparin basically does is "hang out" in the IV line. It is not a high enough dose to be therapeutic - meaning it's not high enough to change the baby's bleeding times and things like it would do for an adult recieving very high doses.
