title: Laryngeal incompetence during neuroleptanalgesia in combination with diazepam.
abstract: In eight patients, following carotid angiography under neuroleptanalgesia, a radiopaque dye was instilled into the pharynx. The chest was x-rayed 15 min later. All eight patients were observed to have aspirated the dye. The technique of neuroleptanalgesia described should not be used without safeguarding the airway in patients liable to regurgitate and inhale gastric contents.
