安氟醚低流量紧闭麻醉的临床观察

Clinical Observation of Micro-flow Close Circuit Anesthesia with Enflurane

目的和方法：采用低流量（０．２Ｌ／ｍｉｎ）新鲜气体（氧）与安氟醚麻醉，并与高流量（２Ｌ／ｍｉｎ）安氟醚麻醉者比较。监测气管插管后５ｍｉｎ、１０ｍｉｎ、１５ｍｉｎ、３０ｍｉｎ和６０ｍｉｎ直至术终的ＭＡＰ、ＨＲ、ＳｐＯ２、ＦＩＯ２、ＰＥＴＣＯ２、ＦＩＥｎｆ、ＦＥＴＥｎｆ及新鲜气体流量。记录手术结束至拔管的时间及清醒程度。结果：两组差异均无显著性意义（Ｐ＞０．０５）。结论：低流量新鲜气体麻醉与高流量同样安全，且麻醉过程平稳，节省挥发性麻醉药，不污染手术室环境。

bjective and Methods:34 patients,ASAⅠⅡ,undergoing elective surgical operations under enflurane anesthesia were studied.Enflurane anesthesia with low oxygen flow.(02L/min) was practiced in 19 surgical patients,which was compared with high oxygen flow (2L/min) in 15 patients.MAP,HR,SpO2,FIO2,PETCO2,FIENF and FETENF were monitored at 5,10,15,30,60 min and end of operation after intubation. The time from the end of operation to extuhation and the degree of awakening were observed as well.Results:The monitored parameters had no any significant deference between two groups (P>005).Conclusion:Low flow enflurane anesthesia is safe and more steady in maintenance of anesthesia than high flow .It may save anesthetics and doses not pollute the environment.
