It has been suggested that the oxides of nitrogen (NO_x) are produced as the result of the use of energy-releasing devices during surgical procedures, such as electric cauteries and portable X-ray machines, under the anesthesia with nitrous oxide. In the first, we have tried it in the experimental conditions, and next in the surgical operating theater. In the experimental condition, placing a chop of beef on the patient plate electrode (disposable) in separable flask, and in which flowing through the nitrous oxide and air mixed gas, we collected the gas, after turning on for 2 second several times in cutting condition (CSV Bovie, Ritter Co., U.S.A.), into 100m1 syringe. And during the electrical cutting of fascia and muscle in the operation of arthro-plasty of hip joint, the gas of the operating field was collected into the steril syringe. Using the analysis of chemical colour reaction, the concentration of the nitrogen oxide was 3.3 times higher than the controle value (before the electrical cutting). It was far more smaller value than the Air Quality Standard of Japan (as NO_2,0.04-0.06ppm).
