neuroleptanesthesia /-lept′anəsthē″zhə/ [Gk, neuron + lepsis, seizure, anaisthesia, lack of feeling] , a form of anesthesia achieved by the administration of a neuroleptic agent, a narcotic analgesic, and nitrous oxide with oxygen. Induction of anesthesia is slow, but consciousness returns quickly after the inhalation of nitrous oxide is stopped.
