用全自动电动麻醉机进行低流量麻醉的临床观察

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落充量麻醉观察。方法 将４８例胸外科 手术病人随机分成两组，分别给予４Ｌ．ｍｉｎ＾－１和０．８Ｌ．ｍｉｎ＾－１流量麻醉，采用Ｃａｐｎｏｍａｃ 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（Ｎ２０、０２、ＣＯ２、Ｉｓｏ），并记录各气体（Ｎ２Ｏ、Ｏ２、Ｉｓｏ）及钠石灰消耗量，将两监测系统监测值

Clinical study of low flow anesthesia with electronic universal anesthetic apparatus

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
