    For all external catheters (no matter the type-PICC, tunneled CVC; temp CVC) our heparin flush is 30 units/3mL


    If a port is accessed and heparin locked:  same 30 units/3 mL


    On port de-access/monthly flush 300 units/3mL (all patients)


    If just doing a weekly port change 30 units/3 mL

    Kindly appreciate your help in providing me with the Flock Lock pediatric protocol for CVAD.

    Especially PICC lines.
    – Do you flush PICC lines for patients more than 40 kg with 100 units heparin per  ml (2ml) in each lumen  for locking of 24 hours
    and if the patient is less than 40 kg with 10 units heparin me ml 2 ml in each lumen ?
    – if the heparin lock is for  less than 24 hours example every 12hours , do you flush the lumens with with 10 unit heparin per ml ? (2 to 3 ml in each lumen)?
    – Do you put PICC lines in your table with the non tunneled catheter or alone? Do you apply the same flushing technique for piccs and non tunneled catheters?

    Thank you for your help.
