摘　　要：目的研究手术切口类型和连台手术对I级层流手术室手术过程中空气细菌总数的影响。方法用空气微生物采样器法采集1 000 L空气样本进行细菌培养,对手术过程中的空气浮游菌总数进行检测和评价。结果Ⅰ类和Ⅱ类手术切口手术,手术区空气细菌总数差异性分析:t=0. 40,P=0. 69,周边区空气细菌总数差异性分析:Z=-1. 70,P=0. 097;连台手术与非连台手术,手术过程中手术区空气细菌总数差异性分析:Z=-0. 31,P=0. 76,周边区空气细菌总数差异性分析:Z=-1. 04,P=0. 30.以上差异均无统计学意义。结论Ⅰ类和Ⅱ类手术切口及连台手术对层流手术室动态空气细菌总数均无明显影响。Objective To study the effect of incision type and continuous operations on the total number of bacteria in air during the operation of Grade I laminar flow operating room. Methods During operation,air microbial sampler was used to collect 1 000 L air sample for bacterial culture which was used to detect and evaluate the total number of floating bacteria in air. Results Analysis on the differences of air bacterial counts in surgical area between typeⅠand Ⅱincisions was t =0. 40,P = 0. 69,and that of air bacterial counts in peripheral area was Z =-1. 70,P = 0. 097. Between continuous and discontinuous operations,the difference of total number of bacteria in air of surgical area was Z =-0. 31,P = 0. 76,and that in peripheral area was Z =-1. 04,P = 0. 30. The differences were all not statistically significant. Conclusion There were not obvious effects of incision type and continuous operations on the total number of air bacteria in dynamic air of laminar flow operating room.
