洁净手术环境中控制颗粒污染物的必要性——《医院洁净手术部建筑技术规范》修订组研讨系列课题之二
Necessity of particulate pollutant control in clean operating environment
摘要：
手术感染控制以微生物为首要控制目标，但非生命颗粒污染物（非生物微粒）同样会导致某些手术并发症，如慢性腹痛、腹膜粘连、肉芽肿、女性不育、人工关节松动甚至失效等。引发上述并发症的颗粒污染物尺寸小至不足0.1 μm，大至数mm。0.3～10 μm尺度范围内的颗粒物被认为最具生物刺激性。因此，手术室净化空调系统的功能不应仅满足微生物的控制要求，还必须满足非生物颗粒污染物的控制要求。
Abstract：
The control of the airborne microorganism is always the top object based on the need of surgical infection control. Nevertheless, the aseptic particulate pollutant, i.e. nonbio-particle, causes numerous surgery complications as well, including chronic abdominal pain, peritoneal adhesion, granuloma, female infertility, and implanted artificial joint loosening or failing etc. The size of the particulate pollutant causing complications ranges from smaller than 0.1 μm to several millimeters. The particles of 0.3-10 μm in size are considered to be the most biologically active. So the clean air conditioning system of operating environment must meet the requirements of controlling both of the airborne microorganism concentration and the aseptic particulate pollutant.
