摘　　要：目的　采用高精密度监测设备和手段对全自动电动麻醉机物理性能测定后进行低流量麻醉观察。方法　将４８ 例胸外科手术病人随机分成两组，分别给予４ Ｌ·ｍ ｉｎ－ １ 和０．８ Ｌ·ｍ ｉｎ－ １流量麻醉，采用Ｃａｐｎｏｍ ａｃ Ｄａｔｅｘ ＡＳ／３ 多功能麻醉气体监测仪与麻醉机自身监测系统同时监测环路内各气体浓度（Ｎ２Ｏ、Ｏ２、ＣＯ２、Ｉｓｏ），并记录各气体（Ｎ２ Ｏ、Ｏ２ 、Ｉｓｏ）及钠石灰消耗量，将两监测系统监测值进行相关性分析。结果　除低流量麻醉超过３小时Ｅａｓ ９０１０ 监测系统对ＣＯ２ 监测与Ｄａｔｅｘ ＡＳ／３有明显误差外，对其它各种气体均可准确监测，所测值与Ｄａｔｅｘ ＡＳ／３ 高度相关。低流量麻醉所消耗Ｏ２ 、ＮＯ２、Ｉｓｏ 量约为高流量的１／３。钠石灰消耗约为高流量３倍。结论　低流量麻醉可节省大量麻醉气体，降低费用，减少环境污染。该麻醉机电子控制系统技术精密，可安全地进行低流量和最低流量麻醉。Objective To evaluate the efficacy of low flow anesthesia with Engstrom Eas 9010 electronic universal anesthetic apparatus Methods Forty eight patients undergoing chest operation,were divided into two groups:high flow anesthesia (HFA) and low flow anesthesia (LFA) Anesthesia gases were monitored with Capnomac Datex AS/3 and Eas 9010 monitor system synchronously.The consumptions of N 2O,O 2,isoflurane,and soda lime were measured Results The apparatus had high accuracy gas and anesthetic agent monitor devices except for measuring CO 2, with the time of anesthesia passing by (over three hours),the end of expired carbon dioxide concentration monitored by the apparatus was less correlative with by Datex AS/3,the accuracy of monitoing the expired CO 2 concentration decreased The consumptions of N 2O,O 2 and isoflurane of LFA were one third as much as those of HFA,otherwise soda lime consumption was three times as much as the later Conclusion This apparatus can be used in low flow or even minimal flow anesthesia safely and reliably with a large amount of anesthetic agent being saved and air polution being reduced
