Are there instances when you will forgo dialysis catheter placement and instead use an existing AVF/AVG for an ESKD patient who requires CRRT?

Since continuous renal replacement therapy (CRRT) in our institution can run without anyone in the room, we never do CRRT through a fistula or arteriovenous graft (AVG). While the risk of needles coming out is probably low and the acute drop in pressure may (may?) alarm the machine, the potential co...

This has not happened yet for me. Our ICU nurses manage CRRT, and with this, I would imagine the dialysis nurses would have to cannulate the fistula, and then the ICU nurses would have to take over. It is probably a little risky, as the patient would be on the machine continuously, possibly for days...

An observation: not a rare occurrence -- AV access becomes thrombosed in shock on vasopressors. So, just another piece of information to utilize a catheter for CRRT needs.
