Bioimpedance-based overhydration valuation in peritoneal dialysis patients is not affected by the dialysis fluid intraperitoneal inflow
Journal Title: Postępy Nauk Medycznych - Year 2013, Vol 26, Issue 2
Abstract
<b>Introduction. </b>Peritoneal dialysis fluid in peritoneal cavity affects the body weight, but is overlooked by the bio-impedance measurements, as shown after draining this fluid out.<br><b>Aim. </b>To evaluate if dialysis fluid inflow affects over-hydration measured using bio-impedance method.<br><b>Material and methods.</b> Body Composition Monitor (Fresenius Medical Care) was used to measure water compartments in 5 male peritoneal dialysis patients, prior to, and immediately after dialysis fluid inflow.<br><b>Results.</b> Dialysis fluid inflow did not affect over-hydration measurements, but slightly influenced anthropometric data.<br><b>Conclusions.</b> Bio-impedance is a useful tool to evaluate current over-hydration in peritoneal dialysis patients, but for the best accuracy of longitudinal comparisons the measurement should be done after the dialysis fluid has been drained out.
