To filter or not to filter???Â
Liposyn II insert reads/ " 1.2 micron filterÂ CAN Â be used can be used forÂ 3 in one or fat emulsion alone".
INS Standard 32Â / " For TPN and lipid THAT REQUIREÂ filtration a 1.2 micron filter shall be used" .
Perry and Potter/ "IV filter optional" page 1057
JPEN Vol 13, Issue 6, 641-643/Â "TPN and Lipids...trapped on the filter... may block the catheter during long term therapy, suggests the importance of filtering..."
JPEN Vol 20, Issue4, 296-301/ "FDA Safety Alert recommends in line fianal filtration for all TPN...Lipid globules >5 microns could lodge in the pulmonary microvasculature and produce an embolic syndrome."
Infusion Therapy in Clinical Practice/INS 2001/ " All parenteral solutions should be filtered...a flter SHOULD Not be used with Lipids only...fat emulsions may or not require filtration, depending on manufacturer'sÂ directions..."
So do you or don't you?Â When your institution is doing thousands of these infusions...patient safety and money have to be thought about...the days of "it seems like a good idea" are long gone.Â
