Appreciate if you can share whether midline catheter or extended dwell PIVC can be used to do therapeutic phlebotomy? And if it is safe to use larger size syringe (greater than 10 mL) to draw the blood slowly.
Yes, a large size syringe is often used to draw from an implanted port. This procedure from a midline or long PIVC has no evidence to show outcomes. Thrombosis and absence of blood return is common with a midline so I would think that is not going to be successful. A long PIVC might be if you place a large gauge catheter to allow for the flow of the very thick and viscous blood in these patients. But a large gauge with a short PIVC that is immediately removed following the procedure would be more successful. IMO, a long PIVC large gauge should not be left in place after the procedure due to CVR. But if you can find a very large forearm vein for a large gauge long PIVC then try it, but IMO this defeats the purpose of a long PIVC.
