title: Exposure to anesthetic waste gas in oral surgery.
abstract: Exposure to nitrous oxide and halothane during oral surgery was monitored using a Miran infrared analyzer. A "typical" time-weighted analysis exposure was established for the surgeon, assistant, and anesthetist. Values for halothane ranged from 7.5 to 59 ppm, and for nitrous oxide, from 280 to 90,000 ppm.
