最低流量循环紧闭式异氟醚麻醉中气体浓度及用量的研究

THE STUDY OF ISOFLURANE CONCENTRATICN AND AMOUNT IN THE LOWEST FLOW CLOSE-CIRCUIT ANESTHESIA

最低流量循环紧闭式异氟醚麻醉８９例开胸手术报道，载体新鲜气流量为０．５Ｌ／ｍｉｎ。的纯氧，使用异氟醚挥发罐刻度浓度为１．５～２％，均达到满意的效果。平均使用液体异氟醚为１１．４ｍｌ／人次。此为一种经济，无污染手术室符合我国具体国情的良好的气体麻醉方法。

Using the lowest flow closed-circuit isoflurane anesthesia in chest operation,carrier is oxygen (0.5L/min) and isoflurane anesthetic vaporizer dial is 1.5-2%,get a satisfied result.The mean amounts of isoflurane is 11.4ml.This mothod is non-pollutian operation room inhale anesthesia.
