Two hundred and seventeen total hip replacements were performed during a trial designed to assess the influence of a surgical isolator upon postoperative wound infection. The trial was controlled by performing 108 of the replacements in a standard plenum-ventilated theatre with twenty air changes/hr, which also housed the isolator procedures. Comparative postoperative wound infection rates were 6·4% for the isolator patients and 4·6% for those operated on in the plenum-ventilated theatre. There was intraoperative wound contamination in both groups of patients and, although the isolator reduced wound contamination at operation, this bore no relationship to eventual wound sepsis.
在一项旨在评估手术隔离器对术后伤口感染影响的试验中，共进行了217例全髋关节置换手术。通过在一个每小时换气20次的标准通风手术间进行108例置换手术来进行对照，该手术间也进行隔离器操作。隔离器组患者术后伤口感染率为6.4%，在通风手术间进行手术的患者为4.6%。两组患者术中均有伤口污染，尽管隔离器在手术时减少了伤口污染，但这与最终的伤口脓毒症并无关联。
