Abstract:
Objective To evaluate the body volume status in maintenance hemodialysis(MHD) children with multi-frequency bioelectrical impedance.Methods Nine end-stage-renal-disease patients undergoing MHD from Aug.2011 to Mar.2012 in blood purification department of Beijing Children's Hospital and 171 cases of healthy control group were investigated.Over hydration (OH),total body water(TBW),extracellular water(ECW),i ntracellular water (ICW) of MHD children pre-and post-hemodialysis and healthy children were measured with the body composition monitor which was based on multi-frequency bioelectrical impedance and the values were standardized by body weight to produce TBW％,ECW％ and ICW％.Results There were statistical differences of OH,TBW,ECW and ECW％ before and after dialysis,but no statistical difference of ICW.By contrast,ECW％ values pre-dialysis were higher,but post-dialysis were lower than that of healthy control group.Pre-and post-dialysis ICW％ values in HD children were similar to those of healthy control group.Conclusions ECW％ increased in MHD children;the main function of normal hemodialysis is to remove extra ECW,which has little effect on ICW.The measurement of multi-frequency bioelectrical impedance can provide an objective basis for capacity status.
