Pollution of the atmosphere with halothane has been measured during general anaesthesia for outpatients undergoing dental extractions. The level of contamination was far in excess of that recorded in surgical operating theatres, and halothane was inhaled at similar concentrations by both the anaesthetist and the dental surgeon. The room air-changing system and a local fan had little effect on contamination. Scavenging devices on the exhalation valve of the anaesthetic circuit were only moderately effective in reducing the concentration of halothane in the atmosphere.
在为接受拔牙手术的门诊患者进行全身麻醉期间，对大气中的氟烷污染情况进行了测量。污染水平远远超过外科手术室记录的水平，麻醉师和牙科医生吸入的氟烷浓度相似。房间换气系统和局部风扇对污染影响很小。麻醉回路呼气阀上的清除装置在降低大气中氟烷浓度方面效果一般。
