Email Discussion Group: Heparinized Flush Bowls & Bags

(Thank you to Charlene Houston RN, Winchester, VA, for the current discussion group question, above).

We use 2,000U of heparin in 1L of NS for our flush bowls and 1000U of heparin in 500 of NS for the flush bags. This flush bag comes as a standard mixed bag from Baxter. This is our standard heparin mix for all Art lines in the hospital, so we can convert our flush tubing an bags to an Art line real easy, without changing to a different concentration.

We use 2000u heparin in 1000ml NS for flush bowels and 1000u/500mlNS for flush/ pressure lines.

We mix 3000U/500cc NS. Each procedure has two bags of flush; one for the table, one to hang and connect to the manifold.

Our angiography laboratory uses heparin (1000 Units : 500 ml. of 0.9% NaCl) 2 units/ml. for our flush bowls. The solution is actually the same as the premixed bags of heparinized solution we use to maintain our arterial lines.

In our cath lab (Lawrence and Memorial Hospital, New London, CT), we use heparin 2u/ml in both our flush bowls and our bags.

In the facility I work in, we use 5000Units of heparin in 1000ml of normal saline. In the dump station the flush bag is 1000Units of heparin in 500 ml of normal saline.

We use 3000U heparin in 500ml NS for both flush bowls and bags.

Our hospital has discontinued use of heparin in the arterial line and swan ganz pressure lines. We are entertaining the idea of not using hepainized saline for the angiogram procedure, on the table and in the transducer line. Are any other hospitals using plain sterile saline as table fluids? If so, what research have you seen? I've been trying to find some data and studies regarding this and have been unsuccessful so far. Thanks

Hi Swanee,

At our Hospital the cost of a 500 cc Heparin bag is $8.22 a bag. vs 90 cents for none Heparin bag of the same size.

Have you found any information on not using Heparin at the table"s.

You can also call me if you wish. (860-224-5404)

I would like to hear from anyone that has stopped the practice of using heparized saline and is now using normal saline. Are you using it on all procedures or just specific ones? Did you use evidence based practice and where did you find it? Would appreciate some input.

Hi Luann

We are thinking about it. Have you found any information on not using Heparin?
