Advantages of tidal peritoneal dialysis.

Tidal peritoneal dialysis (TPD) was introduced in 1990 in the hopes of improving dialysis efficiency. Studies comparing low dialysate flow rates show that tidal peritoneal dialysis has no clearance advantage over intermittent peritoneal dialysis (IPD). With high dialysate flow rates, TPD may be superior or similar to IPD in efficacy, but it is expensive because of the high volumes of dialysis solution used. However, it provides better fluid flow mechanics and more comfort to the patient owing to fewer alarms and less pain during inflow and outflow.
