The anesthetic apparatus are equipped with waste gas scavenger valves ; Scaveng-OR Gas Evacuator, Air Products and Chemicals Inc., and Ohio Gas Evacuator Relief Valve, Ohio Medical Products Airco Inc. Halothante vapor trapped into pyridine was analysed by the modification of Lugg's ultra-violet spectroscopy. Nitrous oxide gas was measured by ECD gaschromatography. After the induction of anaesthesia, the concentrations of two inhalation anesthetics were under the level of NIOSH recommended value (halothane : 0.5 ppm, nitrous oxide : 30 ppm). But we obtained higher value in some places of the operation rooms during induction of anesthesia. As the most obvious cause of room air contamination, we suggested the leakage from anesthesia apparatus, and emphasized the necessity of further attention on the maintenance of good air condition for the health of operating room personnel.
