Sodium sieving in children.

Sodium sieving is a consequence of dissociation between the amount of water and sodium transported over the peritoneal membrane. This dissociation occurs in the presence of aquaporin-mediated water transport. Sieving of sodium can be used as a rough measure for aquaporin-mediated water transport.

Evaluation of intraperitoneal pressure and the effect of different osmotic agents on intraperitoneal pressure in children.

Objectives: To establish intraperitoneal pressure (IPP) in a relatively large pediatric study group and to study the effects of a 3.86% glucose solution and a 7.5% icodextrin solution on IPP during a 4-hour dwell.

Peritoneal transport characteristics with glucose polymer-based dialysis fluid in children.

Scarce data are available on the use of glucose polymer-based dialysate in children. The effects of glucose polymer-based dialysate on peritoneal fluid kinetics and solute transport were studied in pediatric patients who were on chronic peritoneal dialysis, and a comparison was made with previously published results in adult patients. In nine children, two peritoneal equilibration tests were performed using 3.

Fibrin glue used successfully in peritoneal dialysis catheter leakage in children.

Background: Acute renal failure in infants and small children is generally treated with peritoneal dialysis (PD). Dialysis has to be started immediately after catheter implantation. Early dialysate leakage can complicate the effectiveness of dialysis.

Nutritional effects of increasing dialysis dose by adding an icodextrin daytime dwell to Nocturnal Intermittent Peritoneal Dialysis (NIPD) in children.

Background: To assess the need to adapt dietary prescriptions, we studied potential effects of increasing the dialysis dose by adding a daytime icodextrin dwell, in children on Nocturnal Intermittent Peritoneal Dialysis (NIPD), on peritoneal amino acids (AA) and albumin loss, AA, albumin, cholesterol and fibrinogen plasma levels and nutritional intake.

Methods: A cross-over study in eight children (age 2-12 years) on NIPD at baseline (week 1).

Intervention: to increase dialysis dose we added a daytime dwell with 1100 ml/m(2) icodextrin solution for a week (week 2).
