Introduction Fluid management is an important part of care for haemodialysis patients Wizemann et al. Bioimpedance-guided fluid management in maintenance hemodialysis: Bioimpedance measurements with the Body Composition Monitor BCM fresneius been shown to improve fluid management in haemodialysis.

Discussion Rationale for the need for flexible measurement protocols At a population level, it is becoming well accepted that using BCM as an aide in guiding fluid management in haemodialysis improves outcomes Onofriescu et al.

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. Biomed Phys Eng Express. Effect of change in fluid distribution in segments in hemodialysis patients at different ultrafiltration rates on accuracy of whole body bioimpedance measurement.

The use of measurement time as an interaction term in the models for dialysis patients showed that measured-OH changed by a different amount between the paths. To examine each model, plots of standardised residuals against fitted values were used to check the assumption of homoscedasticity and a Q-Q plot of the residuals was used to assess normality.

American journal of kidney diseases: Statistical analysis 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.

Significance levels were set at 0. The results here confirm that the presence of a vascular access does tend to increase OH. 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. Bioimpedance-guided fluid management in hemodialysis patients.

Body composition monitor (BCM)

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 not appropriate. A larger sample would allow better estimates of these different estimates. Table 3 Model for OH in dialysis patients. By making 8-lead BCM measurements on healthy controls and dialysis patients, the effect of a number of simple alterations to BCM measurements are characterised which will allow these measurements to be made with greater confidence.

The effect of vascular access modality on changes in fluid content in the arms as determined by multifrequency bioimpedance. For haemodialysis patients, height was taken from their clinical notes and pre- and post-dialysis weights were obtained as part of normal care. In principle the models that were generated and validated for the standard path can be employed with alternate paths. Table 4 Relative segmental resistances as a proportion of standard whole body path resistances.

Data are presented for a 60 year old female, where the adjustment for OH with age was Please review our privacy policy. The American journal of clinical nutrition. However, dialysis has been shown to perturb fluid distributions Shulman et al. Journal of renal care. This is related to the effect that ultrafiltration Abbas et al. This is supported by looking at the segmental impedance data.

Assessment of fat-free mass using bioelectrical impedance measurements of the human body. Support Center Support Center.

Sum of segmental bioimpedance analysis during ultrafiltration and hemodialysis reduces sensitivity to changes in body position. One of the implications of preferential removal of fluid from the legs than arms could be that the legs are the last segment that fluid is recruited from. Where accurate monitoring of body composition is important, the standard pathway is preferred and consistency is important. For measurements of R Esubstituting limbs and trunk paths does not significantly alter fgesenius overall path R Efor any of the whole body paths except the leg to leg path which is noticeably lower, consistent with results from the regression model.

Fluid management is an important part of care for haemodialysis patients Wizemann et al. Patient characteristics can be seen bcn table 1.

Bioelectrical impedance analysis–part I: The data from healthy controls suggest that there is no bcn in BCM-measured OH between all the whole-body paths other than the foot-to-foot measurement.

The study was not powered to address the multiple comparisons made by the models – the sample size was fredenius on comparisons between the two primary whole-body paths only. Comparison of intradialytic changes in weight and fluid status.

Clinical journal of the American Society of Nephrology: Pilot work comparing BCM measurements from hand-to-hand and from hand-to-foot showed standard deviations of the mean difference in Ncm of around 1. The evidence supporting this recommendation comes from studies using different bioimpedance with freseenius analysis techniques to the BIS used in the BCM. Preserving central blood volume: However, in practice these requirements would exclude a relatively large number of patients from having BCM measurements.

National Center for Biotechnology InformationU. 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.

The paths included in the model were limited to the 6 whole-body paths: Clinical nutrition Edinburgh, Scotland ;
