I have a new PD patient keep having negative UF 24H urine output <500mL and became fluid overloaded after5 days had to do 1 time back up hemodialysis (he still has a fistula/had been on ICHD for 2 years) , days after I check and did an initial membrane test and resulted to high transport type (cant do PET yet he barely started) , decreased dwell time around 1.5 hours 2 days after changes reviewed treatment still every cycle he has about 3/5 cycles still negative UFs, I had removed last fill on the second prescription change that I did because that made this pt overloaded and absorbs it after long day dwell, what prescription would you recommend?
