They observed changes to the convexity of cat's brain upon IV injection, specifically, they noted that Hypertonic Saline IV injection resulted in maximum shrinkage of the brain in 15-30 mins, while administration of hypotonic solutions resulted in protrusion and rupture of the brain tissue.
Central pontine myelinolysis; Other names: Osmotic demyelination syndrome, central pontine demyelination: Axial fat-saturated T2-weighted image showing hyperintensity in the pons with sparing of the peripheral fibers, the patient was an alcoholic admitted with a serum Na of 101 treated with hypertonic saline, he was left with quadriparesis, dysarthria, and altered mental status
Hypertonic saline and mannitol are the main osmotic agents in use, while loop diuretics can aid in the removal of the excess fluid pulled out of the brain. [ 1 ] [ 3 ] [ 7 ] [ 43 ] Hypertonic saline is a highly concentrated solution of sodium chloride in water and is administered intravenously . [ 3 ]
Saline solution for irrigation. Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm/L or 9.0 g per liter. Less commonly, this solution is referred to as physiological saline or isotonic saline (because it is approximately isotonic to blood serum, which makes it a physiologically normal solution).
In severe or acute hypoosmolar hyponatremia, swelling of brain cells causes various neurological abnormalities, which in severe or acute cases can result in convulsions, coma, and death. The symptoms of chronic syndrome of inappropriate antidiuresis are more vague, and may include cognitive impairment, gait abnormalities, or osteoporosis. [2]
If there is an intact blood–brain barrier, osmotherapy (mannitol or hypertonic saline) may be used to decrease ICP. [33] It is unclear whether mannitol or hypertonic saline is superior, or if they improve outcomes. [34] [35] Struggling, restlessness, and seizures can increase metabolic demands and oxygen consumption, as well as increasing ...
If the sodium level is <120 mEq/L, the person can be treated with hypertonic saline as extremely low levels are associated with severe neurological symptoms. [14] In non-emergent situations, it is important to correct the sodium slowly to minimize risk of osmotic demyelination syndrome.
