Abstract

There is controversy on the toxic level of anesthetic gases in the operating room air. Therefore, scavenging system for anesthetic gases should be established in busy operating rooms. The level of waste anesthetic gases should be monitored and relieved if there is leakage. The changing of technique of anesthesia, diet for liver protection and optimal resting may enhance the health condition of medical personnel in operating rooms. In order to salvage of ozon layer, halogenated agents and nitrousprotoxide should be restricted. Low flow and closed system and techniques other than general anesthesia (eg. spinal, regional...) should be prefered in suitable cases.
