    Subject: Gent. Locking Broviac line – no heparin

    We need to instill a Gent. lock into a lumen of a central line.  Gent. lock is not compatible with heparin like a Vanc. lock is.  How does your institution do a Gent. lock?  Do you flush with NS, flush 10 unit heparin then Gent. lock the line?  Or do you just flush with NS and Gent. lock avoiding the use of heparin?  Thanks for any quick responses.
