Microdialyse et agression cérébrale : importance des études animales

Brain microdialysis allows the exploration of brain extracellular medium. This review discusses the main contribution of brain microdialysis for the knowledge of the pathophysiology of brain ischemia and trauma. We describe fundamental principle of microdialysis, limits, and validated metabolic parameters as the lactate/pyruvate ratio or glycerol. The interest to use microdialysis for testing metabolic hypothesis and potential scientific research ways will also be discussed.
