Use of body composition measurements to guide the assessment of dry weight in anuric dialysis patients: improvements in blood pressure control

Fluid management using a body composition monitor (BCM) based on bioimpedance spectroscopy has been found to be beneficial for maintenance hemodialysis (MHD) patients. Our purpose was to provide a management procedure for the adjustment of post-dialysis overhydration (OH ) and to evaluate whether this approach could improve blood pressure. Post-dialysis fluid status was assessed weekly using the BCM. The reference value of OH and the flow procedure for post-dialysis target weight (PDTW) adjustment were established via measurements of OH in 60 normotensive MHD patients. In the interventional study, we adjusted the PDTW of hypertensive patients to the optimal OH range, with a 0.2-0.5 kg change in PDTW per week. This observational study included 130 anuric MHD patients, of whom 60 were in the pre-dialysis systolic blood pressure (sBP )
