Most meds are compatible with the small percentage of drugs being NaHCO3, Lasix, and some other rare combinations.
In regards to a dialysis catheter they are some of the biggest gauged access lines you could ask for and are amazing to use especially when you want to give blood products very quickly. If you need to use one because you don't have other access the biggest thing you want to do is pull off blood to waste because many times the lines are flushed with Heparin. There are usually numbers on each lumen (1.5 or 1.7cc) and this is the amount of heparin in mLs that the dialysis nurse will sit into the catheter to prevent it from clotting. So as long as you pull off 5-10ccs of blood to waste before using it it should be just fine.
