A prospective study was undertaken to investigate the occurrence and possible sources of microbial contamination in association with open meniscectomy of the knee. Sixty patients were randomized into three closed suction drainage regimens of 12, 24 and 48 hours' postoperative suction drainage, respectively. Specimens for bacterial culture were taken from the joint at the time of surgery, from the surgical suction tips, from the subcutaneous part of the drain surface and from the drain-contained fluid at the time of drain removal. The airborne bacterial contamination showed no marked role in this bacterial invasion into the joint, nor did the use of suction increase the risk. The vacuum suction drain, on the other hand, appeared to carry an obvious risk of bacterial invasion, as a parallel of time. In the present comparison this risk was minimal when the drain was removed 12 hours postoperatively.
进行了一项前瞻性研究，以调查与膝关节开放性半月板切除术相关的微生物污染的发生情况及可能来源。60例患者被随机分为三组，分别进行术后12小时、24小时和48小时的闭式吸引引流方案。手术时从关节、手术吸引头、引流表面的皮下部分以及拔管时引流管内的液体中采集细菌培养标本。空气传播的细菌污染在这种细菌侵入关节过程中未显示出显著作用，使用吸引也未增加风险。另一方面，随着时间推移，负压吸引引流似乎存在明显的细菌侵入风险。在本比较中，术后12小时拔管时这种风险最小。
