OBJECTIVES
The goals were to determine the environmental levels of desflurane waste anesthetic gas and the desflurane occupational exposure of operating room staff during the anesthesia of large animal veterinary patients.
METHODS
Active environmental sampling was performed using single-beam infrared spectrophotometry. Passive sampling with dosimeter badges was used to measure the occupational exposure of anesthesia and operating room staff.
RESULTS
Higher concentrations of desflurane (n = 16) were measured at all recovery timepoints relative to the concentrations measured at all locations and timepoints at the start of anesthesia and surgery ( P < 0.05). Time-weighted average desflurane concentrations from dosimeter badges (n = 310) were higher for anesthesia staff than for other operating room personnel ( P < 0.0001).
CONCLUSIONS
The anesthetic recovery of large animal patients is a period of increased exposure to desflurane waste anesthetic gas for veterinary staff.
目的
本研究旨在确定大型动物兽医患者麻醉期间，废气麻醉剂地氟烷的环境水平和手术室工作人员的地氟烷职业暴露情况。
方法
采用单光束红外分光光度法进行主动环境采样，使用剂量计徽章进行被动采样，以测量麻醉和手术室工作人员的职业暴露情况。
结果
与麻醉和手术开始时所有地点和时间点测量的浓度相比，在所有恢复时间点均测量到更高浓度的地氟烷（n = 16）（P < 0.05）。剂量计徽章（n = 310）记录的地氟烷时间加权平均浓度，麻醉工作人员高于其他手术室人员（P < 0.0001）。
结论
大型动物患者的麻醉恢复期是兽医工作人员接触废气麻醉剂地氟烷增加的时期。
