hypoosmolality

hypoosmolality

Etymology: Gk, hypo + osmos, impulse
a state or condition of abnormally reduced osmolality. The normal serum concentration (millimoles per liter) is 0.43-0.50 times the serum osmolality (milliosmoles per kilogram). A decrease in this ratio is caused by an increase in other osmolutes such as glucose or ketone bodies in diabetes mellitus, urea in uremia, or salicylate in salicylic poisoning. See also osmolality.

To minimize hemolysis after possible fluid absorption, these solutions always contain solutes such as mannitol and sorbitol to reduce their hypoosmolality (1, 2).
The definition criteria by Loh and Verbalis included the following: decreased effective osmolality of the extracellular fluid (plasma osmolality less than 275 mOsm/kg H2O), inappropriate urinary concentration (urine osmolality greater than 100 mOsm/kg H2O with normal renal function), clinical euvolemia, elevated urinary sodium excretion on a normal salt and water diet, absence of other potential causes of euvolemic hypoosmolality (1).
