Recently, I had a pt admitted to the ICU with a LUE av fistula and a LUE Picc line. He was hypotensive, so he got an art line... In his left radial. I was always under the impression that NO lines should be in the extremity, we ended up pulling the presumed infected Picc so that went away. We also switched it to a right radial. It appears the fistula was dampening the art line. Are there any lines that can go in that arm, or should it be a avoided to begin with? The fistula was functional although not in use and he bought him self cvvh.
