Edema is defined as a palpable swelling produced by expansion of the interstitial fluid volume; when massive and generalized, the excess fluid. and generalized edema. The causes of generalized edema in childhood are diverse. Formation of generalizededema involves retention of sodium and water in. Generalized edema is a major presenting clinical feature of children with nephrotic syndrome (NS) exemplified by such primary conditions as.

Conflict of Interest Statement The author declares that the research was conducted in the absence of any commercial or financial relationships that could anssarka construed as a potential conflict of interest. Other observations in experimental animals as well as in humans undergoing repeated plasmapheresis to intentionally produce modest reductions in edemq albumin concentrations show that the transcapillary oncotic gradient is preserved; only with greater degree or more rapid achievement of hypoproteinemia does blood volume fall and edema develops 22 Blood Volume Status Based on clinical observations and theoretical grounds, the long held prevailing opinion has been that children and adults presenting with NS anasarja, are in a state of intravascular volume depletion.
