The incidence of postsurgical clean wound infection in 101 consecutive operations was 1.98%. Staphylococci were the predominant bacteria cultured from the anterior nares of the patients and attending surgical personnel--and were found to colonize the wounds. The nasal carriage rates of Staphylococcus aureus amongst the patients and surgical staff were 12.1% and 17.% respectively. Group III and non-typeable (NT) S. aureus strains accounted for about 65% of S. aureus isolates cultured from the anterior nares. A low incidence of nasal carriage of S. aureus isolates correlated with low incidence of wound sepsis. The operating room air seemed considerably contaminated but this did not reflect in high incidence of postsurgical wound sepsis. Our results suggest patients microflora and operating room air were the major sources of intra-operative bacterial colonization of wound at this centre.
在连续101例手术中，术后清洁伤口感染的发生率为1.98%。葡萄球菌是从患者和手术医护人员前鼻孔培养出的主要细菌，且发现其在伤口处定植。患者和手术人员中金黄色葡萄球菌的鼻腔携带率分别为12.1%和17%。从患者前鼻孔培养出的金黄色葡萄球菌分离株中，III组和不可分型（NT）金黄色葡萄球菌菌株约占65%。金黄色葡萄球菌分离株鼻腔携带率低与伤口脓毒症发生率低相关。手术室空气似乎受到相当程度的污染，但这并未反映在术后伤口脓毒症的高发生率上。我们的结果表明，患者的微生物群和手术室空气是该中心手术伤口术中细菌定植的主要来源。
