Interventions

72 MHD patients were randomly divided into an observation group and a control group (36 each). Computer-generated block randomisation (block size 6) was used with allocation concealed with sequentiall

if it plateaued, the current weight was set as provisional DW. The study compares the overhydration (OH), total body water (TBW), extracellular water (ECW), intracellular water (ICW), as well as the s

Design outcomes

Primary

Measure	Time frame
Achievement rate of dry weight measured using thoracic bioelectrical impedance analysis (NICaS BIA) at baseline and 3-month follow-up	—

Secondary

Measure	Time frame
Incidence of intradialytic hypotension (IDH) measured using real-time bedside blood pressure monitoring at each 4-hour dialysis session over 3 months;Overhydration (OH), total body water (TBW), extracellular water (ECW), intracellular water (ICW), ECW/TBW and ECW/ICW ratios measured using NICaS BIA at baseline and 3-month follow-up;Systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) measured using electronic sphygmomanometer at dialysis initiation, end of ultrafiltration and completion of blood reinfusion per session;Mean ultrafiltration volume and relative blood volume (RBV) fluctuation measured using Fresenius 4008S dialysis machine BVM monitoring system at each dialysis session for 3 months	—
