摘　　要：目的探讨动态条件下洁净手术室空气质量的变化规律及其影响因素。方法采用自然沉降法对20个Ⅲ级洁净手术室空气进行采样检测,其中10个手术室作为对照组;每间手术室按手术区采样60份,周边区80份。结果Ⅲ级洁净手术室手术区自然菌平均菌落数(8.62±4.53)个,周边区(6.15±3.87)个,手术区空气中自然菌数量显著高于周边区(P<0.01),且随着手术室人数和手术时间的增加,沉降菌平均数明显增加。结论Ⅲ级洁净手术室手术过程中空气中细菌数量呈规律变化,手术间人员的活动及人员数量是影响沉降菌数量变化的主要因素之一。OBJECTIVE To study the dynamic changing rule and effective factors of in-door air quality of cleanliness in operating room. METHODS On-the-spot air sampling method was used to examine the efficacy in purifying bacteria in operating room. RESULTS The bacterial count in air of operation area was significantily higher than that of the peripheral area （P〈0.01）. As the time went on, the bacterial count in operating room was increased. CONCLUSIONS The air of grade-3 clean operating room is heavily contaminated, by bacteria in the course of operation. Activity and number of operating staff are the main factors influencing the change in concentration of settling bacteria.
