Study limitations The study was not powered to address the multiple comparisons made by the models – the sample size was based on comparisons between the two primary whole-body paths only. Predicting body cell mass with bioimpedance by using theoretical methods: Unlike controls, there was no difference in LTM or ATM between the sides Appendix 3despite the fact that frsenius access is usually on the non-dominant side.

The mortality risk of overhydration in haemodialysis patients. The 8-lead device does not display Cole-plots or body composition data to allow real-time assessment of artefacts or consistency, so repeat measurements were not made.

Fresenius Medical Care; All BCM measurements were checked visually for artefacts, and repeated fresehius the difference in measured OH was no greater than 0. The estimate of R E from the curve-fitting routine was used as a marker of relative changes in fluid status during dialysis for comparisons between the five body segments, where the whole-body analysis models are fresebius appropriate. To examine each model, plots of standardised residuals against fitted values were used to check the assumption of homoscedasticity and a Q-Q freseniue of the residuals was used to assess normality.

Bcn BCM validation literature also suggests that a bias is introduced into measurements of LTM and ATM when measurements are made immediately after dialysis but within 30 minutes this becomes non-significant. The effect of vascular access modality on changes fresfnius fluid content in the arms as determined by multifrequency bioimpedance. To present the data, results for a 60 year old freseniuus measured on the standard path acted as a reference standard path was taken as hand-to-foot on the dominant side of the body for controls and on and the contralateral side of the body to the most recently used vascular access VA for dialysis patients.

Specifications of an 8-lead BCM measurement. Considering the model results for LTM and ATM in controls, it is important to note that the equivalence of OH across different paths does not translate to these compartments. In particular, there was a significant difference in pre-dialysis BCM-measured OH between the side of the body where vascular access was situated as compared to the contralateral side 0.

The data from healthy controls suggest that there is no difference in BCM-measured OH between all the whole-body paths other than the foot-to-foot measurement. The only investigation to consider alternative paths with BIS measurements was in preliminary work for this study, where it was shown that BCM-measured overhydration OH from the hand-to-hand path is an acceptable alternative to the standard path Keane and Lindley, Recruiting 48 subjects into each cohort would allow differences of 0.

A whole-body model to distinguish excess fluid from the hydration of major body tissues.

Effect of change in fluid distribution in segments in hemodialysis patients at different ultrafiltration rates on accuracy of whole body bioimpedance measurement. Changes in hydration following haemodialysis estimated with bioimpedance spectroscopy.

Methods Subjects Ethical approval was granted by a local ethics committee and all participants provided informed consent. Making BCM measurements post-dialysis introduces a negligible bias to OH measurements but does increase measurement uncertainty, which should be accounted for when interpreting such data.

Any of the whole body paths other than foot-to-foot can bc used as an alternative to the standard path for measurement of OH, with an acknowledgement of the additional uncertainty when interpreting the results. Use of alternate paths The data from healthy controls show that there is no difference in BCM-measured OH between all the whole-body paths other than the foot-to-foot measurement, which had a difference of 0.

The use of mixed-effects regression allowed a model to be built that could account for the repeated measures on an individual from the 8-lead BCM. Assessing fluid change in hemodialysis: Support Center Support Center. European journal of clinical nutrition.

Data are presented for a 60 year old female, where the adjustment for OH with age was 0. Standard and 8-lead BCM measurements were made on healthy subjects on one occasion while dialysis patients had measurements made pre- and post-dialysis.

The American journal of clinical nutrition. For healthy controls, subject was taken as the random effect and path, sex and age were taken as ffesenius effects. Using the segmental resistances in table 4the different path resistances can be built from the segments and referenced to the standard path figure 3.

If that is true, techniques for fluid management based on normalising calf ECF Seibert et al. One of the implications of preferential frseenius of fluid from the legs than arms freseniua be that the legs are the last segment that fluid is recruited from.

Using the 8-lead BCM, the impedances of each limb individually can be isolated bvm 1which can support the results of the regression models. Probing the dry weight by bioimpedance: For measurements of R Esubstituting limbs and trunk paths does not significantly alter the overall path R Efor any of the whole body paths except freseniuss leg to leg path which is noticeably lower, consistent with results from the regression model.

Bioimpedance measurements with the Body Composition Monitor BCM have been shown to improve fluid management in haemodialysis. Significance levels were set at 0. These results suggest BCM protocols can be flexible regarding measurement paths and timing of measurement to ensure as many patients as possible can benefit from the technology.

However, neither BIA or SBIA can adequately distinguish excess fluid from lean and adipose tissue, which left the possibility that the differences observed relate to differences in lean tissue alone rather than excess fluid, particularly given that fistulae fdesenius to be placed in the non-dominant arm of patients. American journal of kidney diseases: Results Model results Patient characteristics can be seen in table 1.

Ethical approval was granted by a local frdsenius committee and all participants provided informed consent. This is consistent with previous work using BIA on controls that demonstrated decreased resistance in the dominant arm compared to the non-dominant arm Bedogni et al. However, in practice these requirements would exclude a relatively large number of patients from having BCM measurements. Bland Altman analysis of the agreement of change in weight and change in OH.
