The present report is a research on air samples taken in the operating theatres environment in the hospitals of Umbria to control in order the concentration of anaesthetics in use and to define ambient pollution and to propose changes. The A.A. have divided operating theatres in for groups to analyze the data: 1) operating theatres where there were both systems: air change system and air intake system; 2) operating theatres where there was only the air-change system; 3) operating theatres where there was only the air intake system; 4) operating theatres where there were no systems. These data have been compared with the limit values advised by N.I.O.S.H. The lowest value of pollution have been recorded in those operating theatres with both systems. The A.A. have also compared the ethrane or other alogenated anaesthetics values in the air-change system equipped operating theatres with those (values) found in the intake-air system equipped operating theatres. The lowest values have been recorded in those operating theatres with normal air-change system. Where changes have been made to improve the operating theatres environment, the A.A. have effectuated new controls and found lower values of the anaesthetics levels. The concentration of anaesthetics appeared lower then before.
本报告是一项关于在翁布里亚地区医院手术室环境中采集空气样本的研究，目的是控制所用麻醉剂的浓度，确定环境污染情况并提出改进建议。研究人员将手术室分为四组来分析数据：1）同时具备空气交换系统和进气系统的手术室；2）仅有空气交换系统的手术室；3）仅有进气系统的手术室；4）没有任何系统的手术室。这些数据已与美国国家职业安全与健康研究所（NIOSH）建议的限值进行了比较。污染值最低的是那些同时具备两个系统的手术室。研究人员还比较了配备空气交换系统的手术室中乙烷或其他卤化麻醉剂的值与配备进气系统的手术室中的值。在配备正常空气交换系统的手术室中记录到的值最低。在对手术室环境进行改进后，研究人员进行了新的检测，发现麻醉剂水平的值更低了。麻醉剂的浓度似乎比以前更低了。
