Heparin Lock Flush Solution, USP is intended to maintain patency of an indwelling venipuncture device designed for intermittent injection or infusion therapy or blood sampling. Heparin lock flush solution may be used following initial placement of the device in the vein, after each injection of a medication or after withdrawal of blood for laboratory tests (see DOSAGE AND ADMINISTRATION, Maintenance of Patency of IV Devices for directions for use).
Heparin lock flush solution is not to be used for anticoagulant therapy.
DOSAGE AND ADMINISTRATION
Parental drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Slight discoloration does not alter potency.
Heparin Lock Flush Solution, USP is not recommended for use in the neonate (see WARNINGS).
Maintenance of Patency of IV Devices
To prevent clot formation in a heparin lock set or central venous catheter following its proper insertion, Heparin Lock Flush Solution, USP is injected via the injection hub in a quantity sufficient to fill the entire device. This solution should be replaced each time the device is used. Aspirate before administering any solution via the device in order to confirm patency and location of needle or catheter tip. If the drug to be administered is incompatible with heparin, the entire device should be flushed with normal saline before and after the medication is administered; following the second saline flush, the heparin lock flush solution may be reinstilled into the device. The device manufacturer's instructions should be consulted for specifics concerning its use. Usually this dilute heparin solution will maintain anti-coagulation within the device for up to 4 hours.
NOTE: Since repeated injections of small doses of heparin can alter tests for activated partial thromboplastin time (APTT), a baseline value for APTT should be obtained prior to insertion of a heparin lock set.
Withdrawal of Blood Samples
Heparin lock flush solution may also be used after each withdrawal of blood for laboratory tests. When heparin would interfere with or alter the results of blood tests, the heparin solution should be cleared from the device by aspirating and discarding it before withdrawing the blood sample.
