We studied the degree of pollution in the operating room by nitrous oxide gas used in anesthesia when the extracorporeal circulation (ECC) for open heart surgeries was employed.Measurement of the gas was performed by placing the sampling inlet at 20 cm from the gas exit of artifical lung of the ECC.Levels over 2000ppm of the nitrous oxide gas were detected at the start of the ECC, and 300 to 500ppm observed during the course. The measured values were influenced mainly by the amount of gas flow to artifical lung, perfusion flow, and the time elapsed between the cessation of N_2O administration and the beginning of ECC.We concluded that the pollution we detected when ECC was in use could not be ingnored.We recommend installation of anesthetic gas scavenging system to all extracorporeal circulation apparatus.
