Can an IV line used for blood infusion be used for infusion of meds if it is rinsed with saline after the meds and before more blood is given? Our policy has been to start a new IV for blood infusion. I need to know if this is necessary. Standards state:"drugs or medications shall not be added to blood or components..."

Our SOP states that drugs cannot be added to a blood bag and only Normal Saline can be used as a prime/flush solution for a blood infusion "Y" set. The nurses and anaesthesiologists routinely reuse the IV line after it's been flushed clear, though.
