1. Our current policy is to change adapters on heplocked lines weekly unless lipids or blood is transfused through them. So, if TPN is administered intermittently, the tubing would be changed at 24 hours and the adapter would be changed weekly which was based on a category II CDC guideline that states “change needleless connectors no more frequently than every 72 hours or according to manufacturers’ recommendations for the purpose of reducing infection rates.”
2. How do you define heplocked lines? When should the adapter be changed on a “heplocked line”? Do you recommend changing the adapter with each intermittent infusion regardless of product (i.e. lipids or TPN)?
