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.
