Eng CSY, et al. - Fluid balance is pivotal in the management of children with chronic kidney disease (CKD) and on dialysis. In a study population comprising children with CKD5-5D and age-matched healthy controls, researchers assessed the correlation between optimal weight by bioimpedance spectroscopy (Wt-BIS) and clinical assessment (Wt-CA). Furthermore, they compared the accuracy of Wt-BIS [relative overhydration (Rel-OH)] against indicators of fluid status and cardiovascular measures. For this patient population, BIS afforded an objective method for the assessment of hydration status. In addition, a marked discrepancy was observed between blood pressure (BP) and hydration status in children on dialysis.
