neuroleptanesthesia

General anesthesia induced by the intravenous administration of neuroleptic drugs in combination with inhalation of a weak anesthetic.

A state of neuroleptanalgesia and unconsciousness produced by the simultaneous administration of a narcotic analgesic agent and a neuroleptic agent, e.g. a mixture of methadone and acepromazine for dogs and a mixture of pethidine and acepromazine in horses, supplemented by the inhalation of nitrous oxide and oxygen.
