[Initial colloid-osmotic status of plasma as a criterion of the severity of gestosis and the selection of hemodilution solution].

Major determinants of the colloid osmotic plasma status have been followed up in 90 pregnant women with various types and severity of toxemia. Toxemia of pregnancy was associated with normo-, hypo- and hyperosmotic states, and severe forms of it, such as pre-eclampsia, most typically coexisted with either increased or decreased osmolality. Toxemia of pregnancy was most severe in preexisting hypoosmotic states. Identification of abnormalities in the osmolality and colloid oncotic pressure may allow differential qualitative and quantitative selection of solutions for fluid therapy and appropriate infusion rates.
