title: Control of occupational exposure to nitrous oxide in the oral surgery office.
abstract: Occupational exposure to inhalation anesthetics can be substantially reduced by control measures that have been recently developed. The incentive for their use should be the suspected relationship between chronic exposure to trace concentrations of agents, such as nitrous oxide, and health hazards. Control measures include the use of a newly developed scavenging nasal mask, relatively gastight anesthetic equipment, and vented suction machine, supported by an air monitoring program. With these measures, the concentration of nitrous oxide inhaled by the oral surgeons studied was reduced 97%.
