My unit is a Level III NICU that does not routinely transduce UAC's. Sometimes the UAC is placed ecause a UVC or PIV can't be inserted. The physician and the NNP's don't want to transduce those lines because of the cost of the transducer. If the infant isn't critically ill and isn't extremely preterm, they don't see a need to monitor invasive BP. I am trying to find evidenced-based practice guidelines stating that all arterial lines should be transduced if that is indeed the case. I know that an infant's condition can change at any time and that the transducer could detect changes. Any help appreciated that I could take to my supervisors for rationale to transduce these lines.
