It's actually quite rare to find places that use heparin these days. From what I understand case studies have shown that using heparin to hep-lock vs 0.9NS has no advantages and can actually be very bad for a patient if the line is FLUSHED without aspiration, especially in those patients with coagulable states (this is what *I* learned in school). The disadvantage to 0.9NS is that in order to maintain patency you must flush Q12 or Q8 with a predetermined (10ml typically) amount of saline. I have never worked at a heparin-using facility, so I don't know if those people have to flush in the same fashion or not.
Finally, all of our dialysis catheters are "locked" with Sodium Citrate now. I am not 100% familiar with this anticoagulant as the dialysis RN's are the ones that dwell the med in the catheters, however from what they have told me is that unlike heparin, when it's disseminated in the blood stream (aka if it was inadvertently flushed through the catheter before aspiration on accident, or if the med was unable to be removed via aspiration), it inactivates nearly instantly so there's little to no bleeding risk. I don't know if this is the truth, but from what they've said this is the reason they've made the switch. ... It keeps the line anti-coag'ed so it remains patent, but also is lower risk than 10k unit dose of heparin.
Ps- I'd use your school's CINAHL access to see if you can find the studies I'm referencing. I no longer have CINAHL or I'd try to do it myself.
Depends on the type of central line being used. Last year during my cancer treatments I had a double lumen central line in my chest, a double lumen Groshong in my left arm, and a double lumen Power PICC in my right arm.
The Power PICC is an open-ended catheter and was flushed with heparin (per manufacturer's instructions) EACH and EVERY time it was accessed; 10ml heparin before any med and 10ml after any med including infusions. Heparin had to be used even after daily blood draws. The tip of an open-ended line will clot off otherwise. Even with this care, a fibrin sheath did develop which was challenging to reopen.
My other two lines had a closed tip on them, and could be flushed with 10ml normal saline ONCE A WEEK. The closed tip helps protect it from clotting.
There were several ER admits and out-patient blood transfusions for me last summer. I had kept the manufacturers instructions to share with those nurses because not all of my nurses understood that the Power PICC needed heparin with every access to the line.
Always check with the manufacturer as well as hospital policy.

I'm sure you meant 10 mls Normal saline before and after each medication, and then the locking solution was with Heparin flush solution. Wow, So sorry that you had so many different types of IV catheters in one years time. And, yes, POWER PICC's do occlude with great frequency and they need to be heperinized.

Hello,
I am a nursing student and I'm trying to find out if there are any hospitals that still use heparin to flush central venous catheters. My school teaches us to use heparin, yet none of the hospitals that I've worked at use heparin. If you use heparin at your hospital, I would love to know what state and what type of hospital (public, private, non-profit).
Thank You,
Allison
