摘要
目的探讨在万级以上手术室延长手术台使用时间的可行性,提出新的符合手术室洁净分级的无菌手术台使用时间标准。方法采用平板暴露法及物体表面涂抹法分别对医院万级洁净手术室进行空气微生物检测及无菌手术台上物体表面微生物检测的采样,取样时间为开台即刻、5、6、7、8 h,取样后立即送细菌培养并计算每个时点的污染率。结果在万级洁净的手术室铺好的无菌手术台可保持较长时间的无菌状态,各时点的污染率分别为0、0、1.19%、1.19%、0.85%,各组差异无统计学意义。结论在现今万级洁净手术室的条件下,新铺设的无菌手术台即使>4 h后仍能保持较长时间的无菌状态。
OBJECTIVE To study the possibility of extending the usage time of the operating table in the clean operating room which degree is 10,000 and above. We proposed a new classification time standard of the operating table which is in line with the use of clean operating room. METHODS We used the plate exposition law transitive table to smudge the law to carry on air microorganism examination and on separately the aseptic surgery table to our ten thousand levels of pure operating rooms the table microorganism examination sampling, the sampling time to begin a performance instantly, 5, 6, 7, 8 h. After the sample, delivers the bacillicuhure immediately. RESULTS In 10000 clean operating room, the paved sterile tables can rhaintain longer sterile, and each time point in infection rates were 0%, 0%, 1.19%, 1.19% and 0.85M, respectively. No significant difference （P〈0.55） between each groups. CONCLUSION Under today＇s 10,000 clean operating room conditions, the time of the new sterile operating table laid sterile state is longer, even if the time of the new paved sterile operating table more than 〉4h, it can maintain a longer period of sterile state.
