Bioelectric impedance predicts total body water, blood pressure, and heart rate during hemodialysis in children and adolescents.

Objective: The purposes of our study were to: (1) assess if changes in the volemic status of children and adolescents over the course of standard dialysis could be observed using bioelectric impedance (BIA); and (2) evaluate whether the variability of blood pressure (systolic blood pressure, SBP; diastolic blood pressure, DBP) and heart rate (HR) could be explained by independent variables from BIA data.

Design: We used a randomized, single-blinded treatment and repeated-measures design.

Setting: This study took place at the DaVita Children's Dialysis Center (Chicago, IL).
