Dexmedetomidine
Conditions
Brief summary
Neuroapoptosis is induced by the administration of anesthetic agents to the young brain. Recent studies showed that the a2-adrenoceptor agonist, dexmedetomidine plays a trophic role during development and is neuroprotective in several settings of neuronal injury in animals. We hypothesized that neuroprotective effect of dexmedetomidine would be associated with evidence of brain injury detected by elevation of plasma concentration of glial fibrillary acid protein in children undergoing general anesthesia.
