One goal in the treatment of dialysis is to
achieve and maintain a euvolemic state. Currently euvolemai and “Dry
weight”
assessment is performed on a trial and error basis. Direct
measurement with BioScan of TBW and EcW can provide additional
qualitative information for assessing volume status.
Estimating optimal Dry weight is important but
difficult to establish with only clinical criteria. Under and over
estimation of dry
weight has been shown to impair the survival and
quality of life of HD patients. Expansion of extracellular volume has
been
associated with hypertension, left ventricular hypertrophy and a
higher mortality rate.
Likewise, underestimation of dry weight results in episodes of
hypotension, cramps and faintness effecting dialysis
adequacy and
contributing to the development of angina and ischemic cerebrovascular
disease.
