Abstract

Anesthetic recovery can be a critical period since neurocognitive problems such as agitation and delirium are often seen during the early recovery phase. We recently demonstrated that an α2-adrenergic agonist dexmedetomidine-induced unconsciousness and accompanying brain dynamics changes were completely and instantly reversed by the α2-adrenergic antagonist in the nonhuman primate model. Active awakening from general anesthesia using its antagonism can contribute to facilitating post-anesthesia recovery and discharge in various patients, and also potentially prevent the neurocognitive problems that are associated with anesthetic emergence and recovery. The latter possibility should be investigated in the translational animal models.
