Suspended particulate matter in an office and laser smoke particles in a laser operative room of the Otolaryngology Department, Ramathibodi Hospital were compared. Suspended particulate matter sizes of PM15, PM10 and PM2.5 were selected due to their impact on health. The amount and sizes of the particles were measured by a laser diode portable dust monitor. The mean and standard deviation were measured every hour for 6 periods and calculated by specific computer software. The amount of suspended particulate matters in the office were within the accepted safety level. The amount of suspended particulate matter including laser smoke particles in the operative room before, during and after each laser evaporative procedure was much higher than that of the office. The amount of suspended particulate matter was dangerous for all personnel in the operative room. Risk management for patients in the operative room should be stressed. The ventilation system of the operative room will be assessed further.
对拉玛蒂博迪医院耳鼻喉科办公室的悬浮颗粒物与激光手术室中的激光烟雾颗粒进行了比较。由于PM15、PM10和PM2.5等悬浮颗粒物大小对健康有影响，因此对其进行了选择。通过激光二极管便携式粉尘监测仪测量颗粒的数量和大小。每小时测量6个时间段的平均值和标准差，并通过特定的计算机软件进行计算。办公室内悬浮颗粒物的数量在可接受的安全水平之内。每个激光蒸发手术前、手术中和手术后，手术室中包括激光烟雾颗粒在内的悬浮颗粒物数量远高于办公室。手术室中悬浮颗粒物的数量对所有人员都有危险。应强调手术室患者的风险管理。将进一步评估手术室的通风系统。
