Abstract Objective To investigate the pollution conditions of anestheic waste gas inhalation in Harbin operation room and develop protective measures accordingly. Methods From January to May 2015, 180 operation room in Harbin were selected from 20 hospitals by convenient sampling method and divided into inhalation group and non-inhalation group according to inhalation anesthesia. The detection rate of exhaust gas and the exhaust gas exceeding rate were compared between the two groups. The self-designed questionnaire was used to assess the congnitive of the operating room staff. Results The detection rate of exhaust gas in inhalation group (98.2%) was higher than that of non-inhalation group (72.8%), with statistically significant difference (P < 0.05). The exhaust gas exceeding rate in inhalation group (58.2%) was higher than that of non-inhalation group (22.4%), with statistically significant difference (P < 0.05). The proportion of choosing anesthetic exhaust gas (98.0%) as the potential risk factors was significantly higher than biological risk factor (80.0%), physical factors (56.0%) and chemical factors (73.0%) in operating room staff. Conclusion Inhalation anestheic waste gas can cause the pollution of the operation room. The staff in the operating room have higher awareness of anesthetic waste gas. It is necessary to take active and effective protective measures.
