Hello there -hoping someone can point me in the right direction - how do I find the latest literature on locking PICCs with heparin or NS? I infused a pt yesterday with an antibiotic who is getting it daily for 6 weeks. The infusion company RN who placed the PICC line simply told him he needed to flush with heparin at the end of each administration. He has been getting Heparin 100unit/ml 5mls each lumen (double lumen) for about a week now from our ED. This is 1000units /day for 42 days! He is on crutches, approx 55 yrs old, and will be having surgery at some point during the next month. To me, this puts him at a huge risk for bleeding after a fall, and also HIT.
How much heparin is too much? INS policies and procedures 4th ed does mention flushing with heparin, but how much? Our hospital policy has not been updated since 2008, and I am the only one questioning this. I would love some feedback and pointers on this -
