title: Sevoflurane postconditioning ameliorates oxygen-glucose deprivation-reperfusion injury in the rat hippocampus.
abstract: BACKGROUND
  Sevoflurane is well known to exert a neuroprotective effect through anesthetic preconditioning. However, its effects on postconditioning, a neuroprotective phenomenon following an insult, have not been well studied.
  
  
  OBJECTIVE
  In this study, we examined the ability of sevoflurane to induce postconditioning in rat hippocampal slices, in vitro.
  
  
  RESULTS
  2%, 4%, and 6% sevoflurane reduced neurophysiologic and morphologic neuronal injury following oxygen-glucose deprivation (OGD) and reperfusion. The quantity of damaged neurons was significantly reduced on immunofluorescence staining; excitatory amino acids (Asp, Glu) increased and inhibitory amino acids (GABA) decreased significantly. The effect was concentration-dependent.
  
  
  CONCLUSIONS
  Postconditioning with sevoflurane reduces neuronal damage after OGD-reperfusion injury in the CA1 area of rat hippocampus, in vitro.
