目的 探讨哈尔滨手术室吸入麻醉废气污染情况,为制订相应的防护措施提供依据.方法 采用便利抽样法选择2015年1～5月哈尔滨市20家医院的180个手术间.按照是否采用吸入麻醉分为吸入组(55间)和非吸入组(125间).比较两组废气检出率和废气超标率.采用自制的调查问卷对医护人员对麻醉废气的认知情况进行调查.结果 吸入组的废气检出率(98.2％)高于非吸入组(72.8％),差异有统计学意义(P＜0.05).吸入组的废气超标率(58.2％)高于非吸入组(22.4％),差异有统计学意义(P＜0.05).手术室医护人员中选择麻醉废气为手术室潜在危险因素的比例(98.0％)明显高于生物性危险因素(80.0％)、物理性因素(56.0％)和化学性因素(73.0％).结论 吸入麻醉可造成手术间麻醉废气的污染,手术室医护人员对麻醉废气的认知度较高,采取有效的防护措施至关重要.%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.
