How does mannitol decrease icp
WebMannitol causes compensatory cerebral vasoconstriction and vasodilation in response to blood viscosity changes There is no proof that osmotic agents such as mannitol lower intracranial pressure (ICP) by decreasing brain water content. An alternative mechanism might be a reduction in cerebral blood volume through vasoconstriction.
