The purpose of this study was to determine the timing and type of surgical field contamination in 50 consecutive resections for advanced head and neck cancer with same-stage tissue reconstruction and to analyze the relationship between contamination and the surgical site infection.
Swabs from the surgical field and from surgical drapes close to the field were taken every 2 hours (at 0 hour, 2 hours, 4 hours, and 6 hours) and sent for a standard microbiological diagnostic procedure. Results were recorded in Microsoft Excel and analyzed with SPSS.
We collected 336 swabs of which 71% were contaminated. Polymicrobial contamination was observed in 153 samples (45%). Twenty-six species of pathogens were found, the most frequent was Streptococcus species. Surgical site infection with positive culture occurred in 3 patients.
In head and neck surgery for advanced cancer, standard aseptic procedures do not prevent contamination of the surgical field with physiological bacterial flora of the skin and oral cavity. Although contamination was common, surgical site infection was rare.
本研究旨在确定50例连续进行的晚期头颈癌切除并同期进行组织重建手术中手术区域污染的时间和类型，并分析污染与手术部位感染之间的关系。
每2小时（0小时、2小时、4小时和6小时）从手术区域及靠近该区域的手术单上采集拭子，送去进行标准微生物诊断程序。结果记录在Microsoft Excel中并用SPSS进行分析。
我们共采集了336份拭子，其中71%受到污染。153份样本（45%）观察到多种微生物污染。发现了26种病原体，最常见的是链球菌属。3例患者发生了培养结果为阳性的手术部位感染。
在晚期癌症的头颈外科手术中，标准无菌操作不能防止手术区域被皮肤和口腔的生理性细菌菌群污染。虽然污染很常见，但手术部位感染很少见。
