I recently had a pt. in the CCU with a Tandem Heart PVAD and just came back from having a ventricular ablation. The PVAD was in his right groin, both lines, and there were two venous and one arterial sheath in his left groin. He was dropping his H/H and the PVAD was starting to chug a bit, so we needed to give fluids and blood. I was running out of line space and was curious if his arterial sheath in the groin could be a viable spot to run the blood though, however, no one on the unit knew, and I have been having a hard time finding out an answer online to such a specific question. I understand that infusing drug or other fluids into a radial line can damage vessels easily, but simply running blood through an artery with such a high flow rate should be OK, but I just don't know. What are your thoughts? Thanks!!
