Rapid plasma volume decline upon quiet standing reflects large filtration capacity in dependent limbs. Fresenius Medical Care; Calf bioimpedance spectroscopy for determination of dry weight in hemodialysis patients: This characterises the individual differences in fluid status and body composition and accounts for this when describing the differences between the paths at the cohort level.

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. This is supported by looking at the segmental impedance data.

Current opinion in clinical nutrition and metabolic care. Introduction Fluid management is an important part of care for haemodialysis patients Wizemann et al.

The effect of vascular access modality on changes in fluid content in the arms as determined by multifrequency bioimpedance. Fluid shifts from the limbs into the trunk manifest as an apparent decrease in ECF when measured by whole-body techniques and shifts from the trunk to the limbs as an increase in ECF Lundvall et al.

Measurements over the first 75 minutes of dialysis using BIS Shulman et al. This gave the possibility of making BCM measurements across a number of paths and also allowed the isolation of individual segments for measurement see figure 1. Unlike controls, there was no difference in LTM or ATM between the sides Appendix 3despite the fact that vascular access is usually on the non-dominant side.

Does the presence of an arteriovenous fistula alter changes in body water following hemodialysis as determined by multifrequency bioelectrical impedance assessment? In bc, uncomplicated individual with relatively common characteristics, standard measurement protocols – from hand to foot on one side of the body avoiding vascular access sites – and decision making algorithms are likely to be beneficial.

In principle the models that were generated and validated for the standard path can be employed with alternate paths. Support Center Support Center. Journal gcm Applied Physiology. To investigate the validity of post-dialysis measurements, the agreement between change in BCM-measured OH from the reference path and change in weight was assessed using Bland-Altman analysis.

The 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. Use of hand-to-hand measurements for body composition monitoring in patients freseenius inaccessible or amputated feet.

This is deemed an acceptable sample size; differences below 0. Effect of change in fluid distribution in segments in hemodialysis patients at different ultrafiltration rates on accuracy of whole body bioimpedance measurement. Measurements of resistance, reactance and phase angle were made at the same 50 frequencies as in the standard BCM, for seventeen combinations of voltage ncm current see fig.

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. However, dialysis has been shown to perturb fluid distributions Shulman et al. 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.

This is related to the effect that ultrafiltration Abbas et al. Difference is relative to the dominant path.

The American journal of clinical nutrition. Heavily bandaged limbs, damaged skin and amputations can prevent the use of the standard measurement path, while some complications may not prevent a measurement but will significantly affect the quality of the measurement — e.

Study limitations The study was not powered to bvm the multiple freseniu made by the models – the sample size was based on comparisons between the two primary whole-body paths only. Assessing fluid change in hemodialysis: Validated alternative pathways would allow measurements fresenus be made on patients who would have otherwise have been managed without BCM or managed based on poor quality data.

Bland Altman analysis was done using Analyse-it for Microsoft Excel version 2. Clinical journal of the American Society of Nephrology: This would suggest that relatively more fluid is recruited from the legs than the upper body which is largely in agreement with previous work.

The haemodialysis population is highly comorbid and is disproportionately prone to amputations and tissue viability problems. The effect of arteriovenous fistulae in haemodialysis patients on whole body and segmental bioelectrical impedance.
