Usefulness of peritoneal equilibration test (PET) per volume to estimate the peritoneum type in children with chronic peritoneal dialysis

Abstract

The peritoneal equilibrium test (PET) is the conventional method to assess the permeability of the peritoneal membrane. Also, prescribes dialysis by identifying the type of peritoneal transport through the drained volume and the net ultrafiltration (UF). We studied 33 end stage renal disease (ESRD) patients under 16 years age determining the standard test of peritoneal equilibrium, and the drained volume. The mean PET volume was 1470 ml ± 450 ml. The mean drained volume was 1720 ± 545.2 ml and the mean net UF was 249.4ml  ± 147 ml. Based on the net UF and the creatinine D/P rate, 40% of patients showed a high peritoneal transport. The UF during the 4 h PET was 275.8 ml ± 126.8 ml. The net UF of the PET and the 4 hs infused volume showed a significant association (p < 0.05). It is possible to determine the transport characteristcs of the peritoneum according to the drained volume.
