In my IR (Radiology) dept. we are having a crisis over the fact that we really don't know what is the best way to deal with the old line when doing dialysis line exchanges. We all have great ideas but it is becoming very inconsistant and cumbersome.Currently- A circulating tech/nurse will remove the dressing, don sterile gloves and clean the catheter with a dressing tray while the scub nurse/tech prepares the tray. The first tech/nurse will then hold the catheter up while the second person cleans the skin. A sterile gauze is wrapped around the ends so the radiologist does not actually touch the catheter during the procedure. Does anyone out there have any comments/ideas for us? We recently had some lines come back infected and attributed to us so we want to do whatever will help.
