We are currenly revising our blood products administration policy when I re-read standard 48 V. Blood and blood components.
48.1 Administration seta and . . . .shall be changed after each unit or at the end of 4 hours, whichever comes first.
I always interpreted that to say the 4 hour time period was the determining factor as to how long the tubing could hang. Our currently policy states that 2 units or 4 hours which ever occurs first . . . . . meaning if you can get 2 units completed in 4 hours that was acceptable.
CDC does not state every unit, it states w/in 4 hours of start of infusion. The AABB states at the end of 4 hours. The manufacturer (of the blood tubing) claims the filter is good for multiple units and that policy and procedures should be established by the individual institution.
My question is this: If the tubing should be changed after every unit, what is the research that supports that claim? It seems it would be more of an infection risk to change the tubing every two hours for a patient getting multiple units.
I am hoping someone can clarify this for me.
