Effectiveness of operating room environment in preventing artificial joint replacement infection / 中国组织工程研究

ABSTRACT

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.
