摘要
目的 评价国产XF 980 1型麻醉废气吸附器对氮氧化物、氟化物的吸附效果。方法 选择两个条件基本相同手术间 ,安氟醚或异氟醚 /氧化亚氮静吸复合麻醉的全麻病人 30例。在用国产XF 980 1型麻醉废气吸附器的前、后 ,对麻醉机废气排出口处氮氧化物及氟化物浓度进行监测。结果与使用麻醉废气吸附器前相比 ,使用麻醉废气吸附器后麻醉机废气排出口处氮氧化物、氟化物明显降低 (P <0 0 1)。结论 使用挥发性麻醉药时采用国产XF 980 1型麻醉废气吸附器可明显改善手术室内空气质量。
Objective To evaluate the effects of applying XF-9801 type of anesthetics waste gas absorber, an activated carbon filter,to removing nitrogen oxides (NOx) and fluoride. Methods Thirty patients, undergoing general anesthesia with enflurane or isoflurane/nitrous oxide, were enrolled in this study.The gas samples were taken at the waste gas outlet of anesthetic machine,to identify the concentrations of nitrogen oxides and fluoride before and after the application of anesthetics waste gas absorber. Results Compared with those before the absorber application, nitrogen oxides and fluroide concentrations in anesthetic waste gas decreased significantly following the absorber application (P<001). Conclusions The application of XF-9801 type of anesthetics waste gas absorber can greatly improve the air quality in operating room.
