Hypermagnesemia does not prevent intracranial hypertension and aggravates cerebral hyperperfusion in a rat model of acute hyperammonemia
Peter Nissen Bjerring, Martin Eefsen, Fin Stolze Larsen, William Bernal, Julia Wendon – 7 March 2011 – Intravenous infusion of magnesium sulfate prevents seizures in patients with eclampsia and brain edema after traumatic brain injury. Neuroprotection is achieved by controlling cerebral blood flow (CBF), intracranial pressure, neuronal glutamate release, and aquaporin‐4 (Aqp4) expression. These factors are also thought to be involved in the development of brain edema in acute liver failure.
