Bioimpedance analysis (BIA) is reported to be useful in assessing dry weight (DW) in patients on hemodialysis (HD), but its exact role has never been clearly defined. We reviewed our experience of using the BIA measure of reactance (Xc) in pediatric patients on chronic HD. Our approach is currently based on identifying a range of patient-specific Xc values at which a child can be considered at DW according to a multidisciplinary assessment. Values lower than the patient-specific limit suggests the need for a reduction in DW, whereas values higher than the limit suggest that DW should be increased. The accuracy of our approach was retrospectively assessed by analyzing the left ventricular mass index (LVMI) and the incidence of pulmonary edema (PE) in two groups: The first consisted of 13 patients (median age 15.6years) on dialysis in 2007, before the introduction of the BIA-based approach; the second included 18 patients (median 14.8years) on dialysis in 2011. In 2007, three children experienced four episodes of PE, whereas no PE occurred in 2011. The median LVMI was 56.8g/m2.7 in 2007, and 44.5g/m2.7 in 2011 (P38.5g/m2.7) was 92.3% in 2007 and 61.1% in 2011 (P
