Neuroleptanalgesic anesthesia
editNeuroleptanalgesic anesthesia from Greek, neurolepsis - seizure and analgos - without pain.
First neuroleptanalgesia is produced by a combination of an opioid analgesic such as fentanyl and a neuroleptic like droperidol or haloperidol. After administering nitrous oxide with oxygen neuroleptanalgesia can be converted to neuroleptanesthesia.
