However, clinical experience with thoracic bioimpedance in patients on dialysis is limited. To test the reproducibility of whole body and thoracic bioimpedance measurements and to compare their relationship with hemodynamic changes during hemodialysis, these parameters were measured pre- and end-dialysis in 54 patients during two sessions. The resistance from both bioimpedance techniques was moderately reproducible between two dialysis sessions (intraclass correlations of pre- to end-dialysis whole body and thoracic resistance between session 1 and 2 were 0.711 [0.58-0.8] and 0.723 [0.6-0.81], respectively). There was a very high to high correlation between changes in ultrafiltration volume and changes in whole body thoracic resistance. Changes in systolic blood pressure negatively correlated to both bioimpedance techniques. Although the relationship between changes in ultrafiltration volume and changes in resistance was stronger for whole body bioimpedance, the relationship with changes in blood pressure was at least comparable for thoracic measurements. These results suggest that thoracic bioimpedance, measured by a wearable device, may serve as an interesting alternative to whole body measurements for continuous hemodynamic monitoring during hemodialysis. | Notes: | Schoutteten, MK (corresponding author), Hasselt Univ, Fac Biomed & Life Sci, Limburg Clin Res Ctr, Mobile Hlth Unit, Diepenbeek, Belgium.; Schoutteten, MK (corresponding author), Ziekenhuis Oost Limburg, Dept Future Hlth, Genk, Belgium.; Schoutteten, MK (corresponding author), Imec Netherlands, Dept Hlth Res, Eindhoven, Netherlands. melanie.schoutteten@uhasselt.be |
