Hi there, I am a new grad and have a question regarding heparin drips. I have been researching them because I know that we sometimes see them on the floor I work on. I found my hospital's policy and procedure and have got lots of info from that, but still am wondering about how long a diluted bag of heparin can hang for. I think it is 24 hours, but it does not say on the P&P. What would happen if it hung longer than that? Would it just not be as effective? Thanks in advance.
