It is FDA-approved for use in … WebMannitol lowers the intra cranial pressure through two effects in the brain. The first, rheological effect, reduces blood viscosity, and promotes plasma expansion and cerebral oxygen delivery. In response, cerebral vasoconstriction occurs due to autoregulation, and cerebral blood volume is decreased.

WebMannitol and furosemide are used to reduce increased intracranial pressure (ICP) and to reduce brain bulk during neurosurgery. One mechanism by which these changes might occur is via a reduction in brain water content. WebAug 11, 2015 · Mannitol is frequently used in the management of patients with spontaneous intracerebral hemorrhage (ICH), 1 particularly in China 2 and India. 3 It is an intravascular osmostic agent that establishes an osmotic gradient between plasma and neurons, thereby drawing water from the cerebral extracellular space into the vasculature to reduce ...
