关节置换术相关感染监测和分析

The monitoring and analysis of arthroplasty related infection

目的:对我院关节置换术的相关感染情况进行监测和分析,为预防关节置换术后感染提供依据。方法:2008年7-8月对我院进行的9台关节置换手术进行了相关感染监测。采用5点采样法对面积约30m2的手术室空气进行了4次采样和细菌培养。通过棉拭子采样法对手术医师手部和手术器械(止血钳、手术剪、拉钩)分别进行14人次、76次采样并细菌培养。结果:手术间空气中浮游菌总数平均值为88.2cfu/m3。对参与关节置换手术的医师手部检测中有8人次的细菌培养为阳性。暴露于空气中不同时间的未使用手术器械和使用不同时间后的手术器械细菌培养结果中有11次样本为阳性。结论:在关节置换手术中,手术人员要尽力维护手术间的空气洁净度,遵守外科洗手规则,减少无菌台在空气中的暴露。

Objective ：To monitor and analyze the arthroplasty related infection situations of Drum Tower Hospital, so as to provide evidences for the prevention of infection after arthroplasty. Methods： Monitoring of infection situations of nine arthroplasty operations were carried out from July to August in 2008. Five sampling methods were used to monitor the air of the 30 m2 surgery for 4 times. Through the cotton swab sampling, hands of 14 surgeons and 76 samples of surgical instruments（forceps, surgical scissors, retractors） were collected and then for bacterial culture. Results：The average amount of the total number of free-floating bacteria in our surgery was 88.2 cfu/m3. For the germicnlture, 8 samples of hand detections were positive ; 11 samples of surgical instruments including those used and unused and exposed at different times were positive.Concluslon：In the surgery of arthroplasty, all operation personnels should protect the air cleanliness degree, obey the surgical hand-washing rules and diminish the exposed time of aseptic table.
