Solute-Free versus Electrolyte-Free Water Clearance in the Analysis of Osmoregulation

Abstract

E-CH2O is a more correct parameter than CH2O with regard to the regulation of both plasma sodium and plasma osmolality. However, there is the opinion that the concept of E-CH2O is difficult to understand and that E-CH2O is still not a generally accepted parameter. It is expected that the results of the present study will lead to more general acceptance.
