摘　　要：指出手术室需要通风,需要净化通风和空调。采用什么样的净化标准和措施,应根据手术室卫生学标准确定。100级洁净手术室采用传统的全面层流其性价比不高,建议采用低湍流度置换流的局部集中顶送风,将原来乱流散布的风口集中于手术台上方布置,并适当扩大其面积,当送风面积达到手术室面积的1/10~1/8时,可实现手术区100级、周边区1 000级的洁净度目标。详细分析了这种送风方式的特性、参数、经济性及实测效果。Points out that an operating room needs ventilation, purified ventilation and air conditioning. Purification standards and measures should be determined according to the hygienic standard of operating rooms. It is not cost efficient to adopt the traditional comprehensive laminar flow in a 100 level clean operating room. Recommends using the local top centralized air supply with low turbulence intensity displacement flow. The cleanliness goal of 100 level in the operating zone and 1 000 level in the surrounding area can be achieved if the supply air outlet is arranged on the top of the operating table and its area is expanded to 1/10 to 1/8 of the operating parameters, economics and measured effectiveness of
