摘　　要：目的 :观察低流量麻醉的安全性及其优点。方法 :110例全麻病人随机分低流量麻醉 (LFA)组 (n =88)和高流量麻醉 (HFA)组 (n =2 2 )。LFA组接受半紧闭系统N2 O -O2 -异氟醚低流量麻醉 ,并与 2 2例HFA进行对比研究。整个麻醉过程中连续监测呼末N2 O浓度 ,呼末异氟醚的浓度 ,FiO2 、SpO2 、EtCO2 、HR和MAP。结果 :两种麻醉方法的安全性相同 ,低流量麻醉可以节省挥发性麻醉药和载气 74%～ 90 % ,减少污染。结论 :在麻醉机性能可靠的情况下实施低流量麻醉安全可靠 ,麻醉平稳 ,苏醒快 ,可节省大量的麻醉药 ,减少污染 。Objective: The purpose of this study was to observe the safety and the advantage of the low-flow anesthesia (LFA). Methods: One hundred and ten patients undergoing general anesthesia were randomly divided into two groups: LFA group(n=88) and high-flow Anesthesia(HFA) group(n=22).The patients of LFA group were undergone semi-closed circuit LFA with N 2O-O 2-Isoflurane and compared with HFA group. The end expiratory nitrous oxide and Isoflurane cencentration, FiO 2, SpO 2, EtCO 2, HR and MAP were monitored continuously during the whole procedure Results: The safety of the two groups was much the same. 74%～90% of volatile anesthetic and carrier gas can be saved in LFA group, and it can decrease pollution in operation room. Conclusion: In view of the reliable function of the anesthesia machine, the advantages of the LFA are as follows the anesthesia is safe, reliabe and stable; patients regain consciousness quickly; large amount of anesthetic can be saved and the condition of the inhalating gas can be improved.
