Operating-room personnel exposed over a long period to trace concentrations of anesthetic gases may acquire both organic disturbances and impairment of cerebral function, though this has not been proven. However, the dangers of miscalculations due to disturbances of cerebral function and the fact that all working personnel should be breathing unpolluted air are sufficient indications to make scavenging of anesthetic gases mandatory. Scavenging has been carried out in many hospitals. At Vancouver General Hospital venting of the gases has decreased the nitrous oxide pollution to what is considered an acceptable level.
长期暴露于微量麻醉气体中的手术室工作人员可能会出现机体紊乱和脑功能损害，尽管这一点尚未得到证实。然而，由于脑功能紊乱导致计算错误的风险，以及所有工作人员都应呼吸未受污染空气这一事实，足以表明必须对麻醉气体进行清除。许多医院都已开展了清除工作。在温哥华总医院，气体排放已将一氧化二氮污染降低到了可接受的水平。
