Similar effects of hypertonic saline and mannitol on the inflammation of the blood-brain barrier microcirculation after brain injury in a mouse model.
Summary of "Similar effects of hypertonic saline and mannitol on the inflammation of the blood-brain barrier microcirculation after brain injury in a mouse model."
There has been substantial debate regarding the efficacy of hypertonic saline (HTS) versus mannitol (MTL) in treating moderate and severe traumatic brain injury (TBI). HTS blunts polymorphonuclear neutrophil (PMN) and endothelial cell (EC) activation and reduces tissue edema after resuscitated shock in systemic microvascular beds. MTL also modulates PMN activation markers. It remains unknown if either of these osmotherapies exert similar anti-inflammatory effects along the blood-brain barrier (BBB). We hypothesized that HTS, as compared with MTL, would more greatly reduce PMN-EC interactions, thereby reducing BBB permeability and tissue edema after simulated TBI.

Medical and Biotech [MESH] Definitions
Saline Solution, Hypertonic
Hypertonic sodium chloride solution. A solution having an osmotic pressure greater than that of physiologic salt solution (0.9 g NaCl in 100 ml purified water).
Phosphoric acid esters of mannitol.
Sugar alcohol dehydrogenases that have specificity for MANNITOL. Enzymes in this category are generally classified according to their preference for a specific reducing cofactor.
Solutions that have a greater osmotic pressure than a reference solution such as blood, plasma, or interstitial fluid.
An alkaloid ester extracted from the leaves of plants including coca. It is a local anesthetic and vasoconstrictor and is clinically used for that purpose, particularly in the eye, ear, nose, and throat. It also has powerful central nervous system effects similar to the amphetamines and is a drug of abuse. Cocaine, like amphetamines, acts by multiple mechanisms on brain catecholaminergic neurons; the mechanism of its reinforcing effects is thought to involve inhibition of dopamine uptake.
Object The purpose of this study was to compare the effects of mannitol and hypertonic saline in doses of similar osmotic burden for the treatment of intracranial hypertension in patients with severe...
Purpose The use of hypertonic saline injection in trauma patients is discussed. Summary Patients with hemorrhage, burns, and traumatic brain injury (TBI) may develop hypovolemic shock and require resu...

Hypertonic solutions are mainstay of osmotherapy to cerebral edema. How hypertonic solutions affect healthy brain homeostasis, however, is not fully understood. Using rat model of cerebral edema induc...
The effects of hypertonic saline on hypothalamic paraventricular nucleus (PVN) parvocellular neurons were examined using whole-cell patch-clamp technique. Under current-clamp, 50% (41/82) of parvocell...
The study goal is to compare the management of increased intra-cranial pressure (ICP) using 3% hypertonic saline vs. mannitol (given in same osmolar loads). Primary hypothesis: 1....
The purpose of this study is to evaluate the effect of Hypertonic Saline 7.5% vs Mannitol 20% on brain bulk (using a 4 point scale), intracranial pressure (subdural catheter)and the change...
This is a clinical study comparing the physiologic effects of two hypertonic solutions (mannitol, hypertonic saline) with a particular emphasis on changes in cerebral blood flow in patient...
The purpose of this study is to determine whether hypertonic saline is as much effective as mannitol to treat intracranial hypertension after traumatic brain injury and has at least the sa...
