Background: Ultrafiltration failure is a significant cause of technique failure for peritoneal dialysis and subsequent transfer to hemodialysis. Summary: Ultrafiltration failure is defined as failure to achieve at least 400 ml of net ultrafiltration during a 4 h dwell using 4.25% dextrose. Four major causes of ultrafiltration failure have been described.
12/20/2018 · Ultrafiltration (UF) failure is a common and important complication of peritoneal dialysis ( PD), especially in long-term patients without residual urine production, because it often causes overhydration, which is an important cause of death in this population.
12/20/2018 · Ultrafiltration ( UF ) failure is a common and important complication of peritoneal dialysis (PD), especially in long-term patients without residual urine production, because it often causes overhydration, which is an important cause of death in this population. The current review provides an overview of the pathways of peritoneal fluid transport …
8/17/2009 · One useful definition for ultrafiltration failure status, based on a simple office test, is the following “Rule of 4’s”: give the patient a bag of 4.25% dextrose-based PD fluid for 4 hours. If there is not net ultrafiltration of greater than 400 mL over this time period, then the patient has ultrafiltration failure.
UF failure due to aquaporin deficiency in PD may be yet another type of UFF, albeit rare. Although the etiology is still unclear, it may involve reduction of aquaporins in the peritoneal membrane or may be the result of increased reactive carbonyl compounds (RCOs) and glycation end products related to the use of conventional PD solutions(13–16).
port is available. UF failure is the most fre quent transport abnormality in long-term peritoneal dialysis (PD). It was the main rea son for discontinuation of PD in patients from From the Renal Unit, Department of Medicme, Academic MedIcal Center, University of Amsterdam, Amsterdam, The Netherlands.
1/21/2011 · of a 4-hour dwell of 2.27% glucose dialysate, with a net ultrafiltration volume of less than 100 mL defining ultrafiltration failure. The alternative is the modified PET, which uses 3.86% glucose dialysate. In that test, an ultrafiltration volume of less than 400 mL defines ultrafiltration failure.
Useful in diagnosing ultrafiltration failure which is defined as net UF less than 400 ml after a 4 hour dwell. In general, solute transport type correlates well with 2.5% dextrose PET.
