I assessed a solo2 power PICC and found the purple port had some resistance to flushing, but a normal blood return. The other port had no difficulties either way. I instilled 2mg Cathflo into the purple port and let it sit for almost 1 hr. I then aspirated blood and cathflo and discarded (5cc). Then put on new cap and flushed with saline. The problem is the blood flow is still OK, but the resistance with flushing I orginally encountered is the same--no change after using the Cathflo. Why would there be resistance to flushing when the blood return is normal? Any thoughts? Would it have made any difference to let the Cathflo sit longer? There would be no way to know if it was effective since the blood return wasn't the problem. I haven't encountered this before.
