What is Arrow’s recommended protocol for catheter heparinization and recommended heparin concentration?
To maintain patency of the catheter between treatments, a heparin lock is usually instilled in each lumen of the catheter. The concentration of heparin, or alternative anticoagulant, should be determined by hospital protocol or physician order. Prior to flushing the catheter, first aspirate out existing lock solution, then flush catheter with saline or as per facility protocol.

If the catheter will not be used, it is recommended that the catheter be flushed and re-locked, usually every 48 hours, but no longer than 72 hours.
