Neuroprotective Effects of Dexmedetomidine in the Gerbil Hippocampus after Transient Global Ischemia

Abstract

The present data demonstrate that dexmedetomidine effectively prevents delayed neuronal death in CA3 area and in the dentate hilus in gerbil hippocampus when the management is started before the onset of ischemia and continued for 48 h after reperfusion. Inhibition of ischemia-induced norepinephrine release may be associated with neuroprotection by dexmedetomidine.
