Fluid loss from the peritoneal cavity by back-filtration through the small pores of the three-pore model.
The partitioning of fluid flows among small and ultrasmall pores of the three-pore model in peritoneal dialysis has been traditionally assessed using 4-hour dwells with 3.86% glucose solutions. Under these conditions, however, back-filtration through small pores has been hard to demonstrate. As nicely shown by Asghar and Davies, however, the use of low-concentration (1.36%) glucose-based solutions allows accurate studies of the partitioning of fluid flows from the peritoneal cavity under conditions of fluid loss.
