Abstract: © 2015 International Society for Hemodialysis. Multifrequency bioelectrical impedance assessments (MFBIAs) aid clinical assessment of hydration status for hemodialysis (HD) patients. Many MFBIA devices are restricted to whole body measurements and as many patients dialyze using arteriovenous fistulas (AVFs), we wished to determine whether AVFs affected body water measurements. We reviewed pre- and post-HD segmental MFBIA measurements in 229 patients attending for midweek HD sessions. Up to 144 were dialyzed with a left arm AVF (L-AVF), 42 with a right arm AVF (R-AVF), and 43 by central venous access catheter (CVC). Water content and lean tissue were greater in the left compared to right arm in those patients with L-AVFs both pre and post dialysis (pre 2.1±0.7 vs. 2.0±0.7L, and post 1.9±0.6 vs. 1.8±0.6L and pre 2.65±0.9 vs. 2.56±0.8kg, and post 2.34±0.8 vs. 2.48±0.8 vs. 2.34±0.8kg, respectively) and were also greater in the right compared to left arm for those patients dialyzing with R-AVFs (pre-HD 1.92±0.5 vs. 1.86±0.6L and post-HD 1.79±0.5 vs. 1.7±0.5L, and pre-HD 2.47±0.6 vs. 2.38±0.7kg and post-HD 2.3±0.74 vs. 1.28±0.7kg, respectively), all Ps<0.05. There were no significant differences in arm volumes or composition pre or post dialysis in those dialyzing with CVCs. Segmental MFBIA detects differences in arm water and lean mass in patients with AVFs. The presence on an AVF increases the water content in the ipsilateral arm both pre and post HD. This increased water content of the fistula arm will not be detected by whole body bioimpedance devices.
