I have a patient with a double lumen PICC who has PN stopped and might be restarted in a few days. She has many IV infusions throughout the day and medical team has asked for extra IV access since PN lumen needs to be left unused and the other lumen is not enough for all IV infusions.
My question is: once PN is stopped and lumen flushed, could it be used for any IVs infusion (fluids, antibiotics) and if PN is restarted, after being flushed, reconnect PN?
I undertsand higher risk of infection when PN is running and need to dedicated one lumen for it, but cannot find any evidence regarding not being able to use a PICC lumen for PN that has previously been used for something else.
Any guidleines/evidence regarding this?
