For a multilumen catheter, our policy states to use the distal port or manufactures recommendation (usually the largest port),
and then designate theÂ lumen as the blood draw lumen.Â Â
Someone yesterday interpreted "designate aÂ lumen" as theÂ lumen could only be used for blood draws and no other infusions or meds.
IÂ respondedÂ that it means use only that port whenÂ drawing bloodÂ andÂ avoid the other ports.
WhenÂ asked why a port needs to be designated, I responded with, "it lowers the risk of infection and occlusion".
Our practice policies need to be supported by EBD, so
I've been asked to provide evidence based documentation thatÂ supportsÂ designating a port of a multilumen catheter for blood draws.
INS standards don't mention designatiing a port (of a multilumen catheter) for blood draws.
