背景：层流手术室应用于人工关节置换，提高了无菌条件，使关节置换后感染得到有效的预防。 　　目的：比较层流手术室与传统手术室环境下人工关节置换手术室菌落数。 　　方法：选择百级层流手术室进行人工关节关节置换手术患者300例，在外院传统手术室进行人工关节置换患者300例，所有患者均未出现感染。随机抽取在百级层流手术室进行人工关节置换患者100例和传统手术室行关节置换者100例，比较两组患者关节置换前后手术室平均菌落数。 　　结果与结论：两组患者关节置换前菌落数比较，差异无显著性意义，百级手术室患者关节置换后沉降菌数明显少于传统手术室(P<0.05)。提示与传统手术室相比，百级层流手术室进行人工关节置换安全性更高，更能有效预防人工关节置换后的感染。

BACKGROUND:Laminar flow operating room used in artificial joint replacement can improve the aseptic conditions and can effectively prevent the infections after joint replacement. OBJECTIVE:To compare the number of colonies during artificial joint replacement in laminar flow operation room and traditional operation room. METHODS:300 patients with artificial joint replacement in hundred-level laminar flow operation room and 300 patients with artificial joint replacement in traditional operation room were selected, and al the patients had no infection. Then 100 patients with artificial joint replacement were randomly selected from the hundred-level laminar flow operation room and traditional operation room respectively. The number of colonies in operation room of two groups was compared before and after replacement. RESULTS AND CONCLUSION:There was no significant difference in the number of colonies between two groups before replacement, and the settling bacteria number of the artificial hip replacement patients in the hundred-level laminar flow operation room was significantly smal er than that in the traditional operation room (P<0.05). The results indicate that compared with the traditional operation room, the hundred-level laminar flow operation room for artificial joint replacement has higher safety and can effectively prevent infections after replacement.
