Hi, they are very difficult patients aren't they.
We don't use sodium profiling, but we do use fluid profiling and generally put them in a profile five (Fresinius machine) which has a cycle of a brief high ufr then drops to a very low ufr as a rest phase.
I had my all time record weight gain today with a patient coming in 8 kilograms ( I don't know what that is in pounds) above his ideal body weight. Of course he doesn't know how he could've gained all that weight!
