Kim H, et al. - Segmental bioimpedance analysis (BIA) can identify fluid volume changes in the arms of patients on hemodialysis (HD) after vascular access surgery. Herein, it was investigated if the difference in fluid volumes between the arms of the patients using segmental BIA was related to vascular access outcome. It was concluded that by calculating the relative difference in fluid volume between the arms of the patients with and without vascular access, segmental BIA could predict vascular access failure in patients on HD.
