Heparin Lock Flush

Clearing intermittent infusion (heparin lock) sets To prevent clot formation in a heparin lock set, inject dilute heparin solution (heparin lock flush solution, USP or a 10 to 100 units/mL heparin solution) via the injection hub in a quantity sufficient to fill the entire set to the needle tip. Replace this solution each time the heparin lock is... 

Use heparin lock-flush solution with caution in infants with disease states in which there is an increased danger of hemorrhage. The use of the 100 unit/mL concentration is not advised because of bleeding risk, especially in low-birth-weight infants.

Use of an ICM (200-400 mg I/ml) in a volume of 5-10 ml is possible (if image quality allows, use a 1 1 dilution with normal saline see fig. 3 and 4). Since CIN is triggered by the amount of administered ICM, it is crucial, especially in patients with renal function impairment, to use as minimal contrast medium (CM) as reasonably possible. An amount of <10 g of iodine (approx. 25 ml ICM with a concentration of 370 mg I/ml) per examination should be aimed at for initial diagnosis. A recent study testing the compatibility of ICM with trisodium citrate, a catheter lock solution as a replacement of heparin, suggests that the catheter should be thoroughly flushed ex-vivo with saline if an ICM has been previously injected. Otherwise, the potential for precipitation is increased [32].
