In a prospective study including 112 patients sources and routes in postoperative wound infections were traced by comparing wound cultures with cultures from the patient, other patients, personnel and from the environment in the operation unit, intensive care unit and in the ward. A total number of about 10 000 cultures was taken. The wound infection rate was 9.8% (8.1% in clean surgery and 13.2% in potentially contaminated surgery). The patient was a source of the bacteria in all cases of wound infection after potentially contaminated surgery and the wounds were probably contaminated intraoperatively. A possible intraoperative wound inoculation was registered at four instances and a postoperative wound inoculation at four instances in clean surgery. It is concluded that surgical wounds can be contaminated both at surgery and postoperatively. Postoperative wound contamination seems to be most important in clean surgery.
在一项纳入112例患者的前瞻性研究中，通过比较手术切口培养物与患者自身、其他患者、医护人员以及手术单元、重症监护病房和病房环境中的培养物，追踪术后伤口感染的来源和途径。总共采集了约10000份培养物。伤口感染率为9.8%（清洁手术为8.1%，可能污染手术为13.2%）。在可能污染手术术后所有伤口感染病例中，患者是细菌的来源，伤口可能在术中被污染。在清洁手术中有4例记录到可能的术中伤口接种，4例记录到术后伤口接种。结论是手术伤口在手术时和术后均可被污染。术后伤口污染在清洁手术中似乎最为重要。
