The aim of this interventional study was to assess the feasibility and clinical consequences of active fluid management guided by bioimpedance spectroscopy in chronic hemodialysis patients.<\/jats:p>\n <\/jats:sec>\n \n Design, setting, participants, & measurements<\/jats:title>\n Fluid status was optimized prospectively in 55 chronic hemodialysis patients over 3 months (November 2011 to February 2012). Predialysis fluid overload was measured weekly using the Fresenius Body Composition Monitor. Time-averaged fluid overload was calculated as the average between pre- and postdialysis fluid overload. The study aimed to bring the time-averaged fluid overload of all patients into a target range of 0.5\u00b10.75 L within the first month and maintain optimal fluid status until study end. Postweight was adjusted weekly according to a predefined protocol.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Time-averaged fluid overload in the complete study cohort was 0.9\u00b11.6 L at baseline and 0.6\u00b11.1 L at study end. Time-averaged fluid overload decreased by \u22121.20\u00b11.32 L (\n P<\/jats:italic>\n <0.01) in the fluid-overloaded group (\n n<\/jats:italic>\n =17), remained unchanged in the normovolemic group (\n n<\/jats:italic>\n =26,\n P<\/jats:italic>\n =0.59), and increased by 0.59\u00b10.76 L (\n P<\/jats:italic>\n =0.02) in the dehydrated group (\n n<\/jats:italic>\n =12). Every 1 L change in fluid overload was accompanied by a 9.9 mmHg\/L change in predialysis systolic BP (\n r<\/jats:italic>\n =0.55,\n P<\/jats:italic>\n <0.001). At study end, 76% of all patients were either on time-averaged fluid overload target or at least closer to target than at study start. The number of intradialytic symptoms did not change significantly in any of the subgroups.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Active fluid management guided by bioimpedance spectroscopy was associated with an improvement in overall fluid status and BP.<\/jats:p>\n
